No full textCymatodera monticola Rifkind, n. sp. (Figs. 34–36) Type specimens. Holotype male: México, Oaxaca, 3 mi N. Suchixtepec, 9500 ’, km 144, Rt. 175, S. Oaxaca, VI- 4- 6 -[19] 71, H. Howden. Holotype deposited in CMNC. Paratypes: MEXICO, OAXACA: 1, same data as holotype; 1, Hwy. 175, 3 mi. N. Suchixtepec, 9500 ’, VI- 4 -[19] 71, D. E. Bright, collector. Paratypes are deposited in JNRC and WFBM. Diagnosis. Separable from other Mexican brachypterous Cymatodera species by virtue of a singular combination of relatively large size (> 10 mm), elongate, subflattened, partially translucent elytra with a strongly bisinuate posterior margin (Fig. 34), and unique pygidial characteristics. Cymatodera monticola is similar to C. barri Rifkind, also a Oaxacan endemic, but in that species the elytral apices are rounded, with the male abdominal tergite 5 deeply incised at the posterior margin, and tergite 6 with the posterior margin usually transverse rather than emarginate. Description. (Holotype). Length: 12.0 mm. Form: elongate, dorsoventrally compressed, brachypterous. Color: reddish brown; head and pronotum a little darker; elytra testaceous and partially translucent, with indistinct brown markings (Fig. 34) as follows: on each elytron a small, oblique macula posterior to base and a small, irregularly sinuate, transverse fascia posterior to middle. A random scattering of elytral punctations are similarly infuscate. Head: measured across eyes, wider than pronotum; surface rather finely punctate and roughened; vestiture inconspicuous, pale, and mostly reclinate; antennae of moderate length. Pronotum: widest at anterior margin; longer than broad (ratio of length to width 3: 2); surface shining, finely, transversely rugulose, coarsely but shallowly punctate anteriorly; vested as on head. Elytra: typical brachypterous form; elongate (ratio of length to width 7: 3); widest at posterior 4 / 7; disk subflattened above; anterior margin narrow, arcuately emarginate; humeri obsolete; posterior margin bisinuate, apices subacuminate; surface shining, with rather deep, moderately to significantly coarse punctures, subserially arranged but not regularly assorted by size; vestiture inconspicuous, rather sparsely arrayed, composed of fine, pale, suberect and erect setae of moderate length. Metaventrite: short, sulcate posteriorly, subconical on either side; surface shining, finely, sparsely, punctulate. Abdomen: ventrite 5 (Fig. 35) with sides oblique; posterior margin deeply, arcuately emarginate; ventrite 6 (Fig. 35) with sides slightly inflected at middle, bowed outwardly posteriorly, each side with a sinuate, posteriorly divergent carina forming a flange distally that narrows to become part of a slightly downcurved, blunt tipped, lateral projection; surface rugose, without a longitudinal carina at middle; posterior margin rather broadly, arcuately emarginate at middle, extended laterally to form interior border of the lateral projections; tergite 5 (Fig. 36) with hind margin bisinuate, slightly, arcuately inflected at middle; tergite 6 (Fig. 36) with sides broadly arcuate, hind angles subacute, hind margin with a broadly V–shaped emargination. Aedeagus: apex of phallus rather sharply upturned. Variation. The female has the abdominal sternites partially infuscate. Ventrite 5 has the posterior margin broadly, shallowly, arcuately emarginate; ventrite 6 has its sides slightly oblique, its hind margin shallowly, triangularly inflected, with a distinct depression at middle; tergite 6 is also shallowly, triangularly inflected at posterior margin, which appears to be folded downward along its length. Etymology. The specific epithet refers to this species’ montane habitat. Distribution. Known only from the Sierra Sur of Oaxaca, México, in the vicinity of San Miguel Suchixtepec. Biology. Specimens were collected at 9500 ’ (2895 m) in early June.Published as part of Rifkind, Jacques, 2015, New species of Cymatodera Gray (Coleoptera: Cleridae: Tillinae) from México and Central America, with notes on others, pp. 519-552 in Zootaxa 3946 (4) on pages 536-537, DOI: 10.11646/zootaxa.3946.4.3, http://zenodo.org/record/23860
Enoclerus melissae Rifkind, n. sp.

Parker, coll. Paratypes are deposited in CSCA, WFBM and JNRC. Diagnosis. Separable from congeners on the basis of coloration, elytral markings and surface sculpturing. The new species' small size, shining metallic blue pronotum and shining deep metallic purple elytra marked with two sets of cream colored maculae make it easily identifiable. Its closest affinity is almost certainly with the species described immediately below, which, however, displays three sets of pale elytral markings. Enoclerus melissae is also somewhat similar to the Brazilian E. lateluteus Pic, though that species is larger, has black antennae and pronotum, and differently shaped median elytral markings. Description (Holotype). Length: 5.60 mm. Color: Head, pronotum and venter dark metallic blue; antennae, mouthparts and legs, reddish testaceous; elytra dark metallic purple–brown, with two sets of cream colored maculae arranged as in Fig. 12, incomplete at lateral margins. Head: shining; sparsely, finely punctulate; set with short and medium length suberect, posteriorly directed ashy setae, intermixed with longer, erect dark setae. Pronotum: a little longer than broad, narrower than elytra at base; transverse impression U–shaped at middle; disk subflattened above; surface shining, punctulate as on head; shallowly, minutely rugulose at sides; moderately but inconspicuously clothed with fine, suberect ashy setae and fewer longer, more robust, erect dark setae. Elytra: elongate (ratio of length to width 17: 10); broadest posterior to middle; umbones prominent; subbasal tumescences obsolete; posterior slope gradual; surface shining, a little more densely and distinctly punctulate than pronotum, punctures appearing dark against cream–colored maculae; vestiture inconspicuous, consisting of fine, suberect, pale setae over pale maculae, and fine, suberect dark setae over darkened integument, intermixed with robust, infuscate, erect setae. Mesosternum: posterior median process slightly raised at apex. Metasternum: convex; shallowly, minutely granulate–punctate; vested with rather long, fine, ashy setae; anterior median process not elevated distally. Abdomen: shining; coarsely, sparsely and shallowly punctate; vested as on metasternum; visible sternite 6 with sides oblique, hind angles rounded, posterior margin slightly inflexed at middle. Visible tergite 6 slightly longer than visible sternite 6; posterior margin narrowly rounded. Legs: robust. Variation. Size ranges from 4.40 mm to 6.20 mm. The female has visible sternite 6 and visible tergite 6 with their posterior margins contiguously rounded. Specimens are otherwise similar. Etymology. I am delighted to name this beautiful beetle for my friend Melissa Brady. Distribution.

Enoclerus regnadkcin Rifkind, n. sp.
No full textEnoclerus regnadkcin Rifkind, n. sp. (Fig. 17) Type specimen. Holotype female: Guatemala, Zacapa, San Lorenzo, 17 –vi– 1993, 1500 m, B. D. Gill, coll. Holotype deposited in CNC. Diagnosis. Distinguishable from congeners based on a unique combination of surface sculpturing, body proportions and elytral color pattern. The new species can be distinguished from E. venator group species and E. signifer Barr by its broad, complete, stramineous median fascia (fascia interrupted internally before suture in the others), and its lack of a sagittate patch of cinereous pubescence on the elytral anterior 1 / 2. From E. crabronarius group species, it can be separated by virtue of its pale basal elytral maculae (absent in E. crabronarius species complex) and by its lack of a basal elytral band of pale setae. Description (Holotype). Length: 7.40 mm. Color: black; antennomeres 1 and 2 (in part) testaceous; terminal labial palpomeres castaneous; elytra with a pair of elongate–ovate stramineous maculae on either side of suture at base, and a broad stramineous fascia at middle, fascia irregularly sinuate at anterior and posterior margins, complete to sides, a bit inflexed anteriorly at suture, complete internally. Head: shining, rather densely, shallowly punctate, moderately densely but inconspicuously clothed with very fine, subrecumbent silvery setae, interspersed with fewer, more robust, erect dark setae. Pronotum: a little broader than long, narrower than elytra at base; anterior margin broadly arcuate at middle; transverse impression distinct, broadly, shallowly U–shaped at middle; disk subflattened above; surface shining, rather densely, deeply and minutely punctate; minutely transversely rugulose at sides; vestiture composed as follows: a rather thin band of fine silvery setae at anterior margin; a dense but inconspicuous covering of short, suberect, dark setae intermixed with longer, more robust, erect, dark setae on disk; a thin concentration of suberect and erect silvery setae of varying lengths on sides and posterior slope. Elytra: elongate (ratio of length to width 7: 4), broadest at posterior 1 / 3; umbones prominent; posthumeral margin gibbose to middle; subbasal tumescences shallow, broadly rounded above; apices separately rounded, slightly dehiscent; surface shining, rather densely, deeply and irregularly punctate, punctures rather fine on either side of suture, more coarse laterally above, growing obscure posterior to median fascia; posterior 1 / 3 shallowly granulate; vestiture mostly inconspicuous, black bands densely set with short, suberect black setae, intermingled with fewer long, erect, black setae; pale median fascia set with short, fine, suberect, stramineous setae and a few long, erect, black setae; elytral apices covered with a conspicuous wedge–shaped band of subrecumbent silvery setae. Mesosternum: posterior median process slightly elevated apically. Metasternum: finely, shallowly and densely punctulate, set with thin, silvery setae; anterior median process not apparently elevated. Abdomen: shining, occasionally set with shallow, coarse impressions; thinly setose; visible sternite 5 with posterior margin broad, subtruncate, very slightly inflexed at middle; visible sternite 6 with sides tapering, hind margin subtruncate at middle. Etymology. The specific epithet is a random agglomeration of letters in honor of economist Peter Bergman (1939–2012), inventor of the "love–in." Distribution. Known from the type locality in eastern Guatemala.Published as part of Rifkind, Jacques, 2012, New Central American and Mexican Enoclerus Gahan (Coleoptera: Cleridae: Clerinae): Part II, pp. 1-27 in Zootaxa 3397 on pages 16-17, DOI: 10.5281/zenodo.21305

No full textEnoclerus gilli Rifkind, n. sp. (Fig. 8) Type specimens. Holotype male: Guatemala, Zacapa, 6 km S. La Unión, 1550 m, May 27, 1997, E. Giesbert, coll. Holotype deposited in CNC. Paratype: 1, Guatemala, Zacapa, 3 km S. La Unión, 6 –vi– 1991, B. D. Gill, coll. Paratype deposited in JNRC. Diagnosis. Most similar to E. semiochraceus (Chevrolat), its probable sister species. Enoclerus gilli, by comparison, has a broader, more transverse midelytral fascia, and lacks the distinctive band of rusty pubescence that encircles the elytral basal tumescences in E. semiochraceus. Description (Holotype). Length: 8.0 mm. Color: black; antennomeres 1 and 2 in part reddish testaceous; mouthparts castaneous; elytra with a broad, transverse, pale orange fascia at middle, complete to lateral margins and across sutural bead. Head: antennae robust; eyes moderate in size; surface densely, minutely but shallowly granulate-punctate, rather densely covered with short, subrecumbent orangish setae, intermixed with fewer longer, erect orangish setae. Pronotum: campanulate; about as long as broad, narrower than elytra at base; anterior margin shallowly emarginate at middle; transverse impression moderately distinct, broadly U–shaped at middle; disk subflattened above; basal collar broad; surface sculpted as on head, rather densely vested with short and medium length, anteriorly oriented, suberect orangish setae, interspersed with a few medium length black setae; vestiture somewhat more thinly arrayed posteriorly at sides. Elytra: elongate (ratio of length to width 31: 16); anterior margin bisinuate; humeri distinct, with umbones prominent, rounded; sides subparallel, slightly inflexed at anterior 1 / 3, widest at middle, arcuately rounded posteriorly to separately rounded, slightly dehiscent apices; subbasal tumescences gibbous, prolonged posteriorly but rounded above, without tubercles; disk subflattened, apical slope moderately precipitous; surface on black integument shallowly granulate, rugulose and occasionally dimpled; surface of pale median fascia rugulose and rather densely, minutely and deeply punctulate; each elytron bearing 3 or 4 longitudinal striae; vestiture as follows: scutellum densely set with stramineous setae; anterior margin with a sparse array of short reclinate and medium length erect, pale orange setae that extends posteriorly at middle beyond scutellum; lateral margins posterior to umbones with a small triangulate patch of reclinate orangish setae; basal black band with a dense covering of short, erect black setae and somewhat fewer longer, erect black setae; median orange band with a moderately dense covering of short, subrecumbent, pale orange setae, intermingled with longer, suberect and erect setae of the same color; posterior 2 / 5 anteriorly with a transverse, hourglass–shaped fascia of dark pilosity similar in composition to basal black band, posteriorly with a covering of orange setae as on median band, complete to apices. Mesosternum: posterior median process distinctly elevated apically. Metasternum: convex; surface roughened, densely set with white setae; anterior median process sulcate. Abdomen: shining; sparsely set with white setae; visible sternite 6 with hind angles rounded, posterior margin slightly emarginate at middle, surpassed by visible tergite 6, which has posterior margin rounded. Legs: robust. Variation. The paratype female measures 8.35 mm in length. It has visible sternite 6 rounded at apex, but is otherwise similar to the holotype. Etymology. The specific epithet is a patronymic honoring its discoverer, my fellow coleopterist Bruce Gill.Published as part of Rifkind, Jacques, 2012, New Central American and Mexican Enoclerus Gahan (Coleoptera: Cleridae: Clerinae): Part II, pp. 1-27 in Zootaxa 3397 on pages 8-9, DOI: 10.5281/zenodo.21305

S. Ross, coll. Paratypes are deposited in ARC, CASC, CNCI, CNIN, EMEC and JNRC. Diagnosis. Most similar to C. discoidalis Chevrolat, with which it is probably sympatric, the new species can be distinguished as follows: it lacks a diamond–shaped postmedian elyral marking; male abdominal ventrite 5 less deeply emarginate by comparison; male abdominal tergite 6 with posterior margin feebly rounded rather than slightly inflexed; elytral apices nearly conjointly rounded (rather broadly dehiscent in C. discoidalis). Description. (Holotype). Length: 10.80 mm. Form: elongate, subcylindrical. Color: testaceous; head, antennae, pronotum, legs and venter (except abdomen), reddish brown to piceous; abdomen mostly chocolate brown medially, lateral sensory depressions and pygidium pale testaceous; elytra (Fig. 63) with a pattern of irregular, rather disrupted, brownish markings, the most distinct of which is a broad, postmedian transverse band. Head: measured across eyes, wider than pronotum; surface deeply, finely punctate and rugulose, densely but inconspicuously clothed with short, fine, adpressed yellowish setae, arranged in whorls, interspersed with a few longer, suberect and erect setae. Pronotum: elongate (ratio of length to width 11: 7); anterior transverse impression distinct, V–shaped at middle; antescutellar impression distinct; subbasal tumescences prominent; surface shining, sculpted as on head. Elytra: elongate (ratio of length to width 13: 5); humeri distinct; sides nearly parallel; apices very slightly dehiscent, almost conjointly rounded; disk subflattened above; surface shining, substriate, very densely covered with small, shallow punctures, and set rather sparsely and irregularly with larger, deeper, infuscate punctures, the latter loosely arranged in longitudinal series. Metaventrite: surface shining, sparsely punctulate, inconspicuously clothed with very fine, pale, subrecumbent setae of moderate length; posterior margin armed with a pair of small, short, sharp, infuscate tubercles at middle. Abdomen: shining; ventrites 1–5 with broad, shallow, rounded depressions laterally; ventrites 1–3 punctured as on metasternum; ventrites 4–6 very densely, finely, granulate–-punctate; ventrite 5 (Fig. 64) short, hind angles subacute, tumid posterior margin rather broadly, arcuately emarginate; ventrite 6 (Fig. 64) with sides slightly curved, hind angles moderately produced, posterior margin deeply incised in an ogee shape; tergite 6 subrectangulate, arcuately inflexed laterally, posterior margin rather broadly, arcuately rounded, surpassing hind angles of ventrite 6 posteriorly. Variation. The female lacks tubercles on the metaventrite; it has ventrite 6 and tergite 6 with the sides rounded and the posterior margin subtruncate, tergite 6 slightly surpassing ventrite 6 posteriorly. The extent of elytral infuscation is moderately variable among the specimens on hand. Etymology. The specific epithet refers to the prevalence of cell–like shapes within the infuscate elytral bands of the new species. Distribution. Known from northeastern Oaxaca and the vicinity of Xalapa, Veracruz state, in México. Biology. Cymatodera cellulosa appears to be a species of cool, humid forests at moderately high elevations. One specimen was taken at blacklight.Published as part of Rifkind, Jacques, 2015, New species of Cymatodera Gray (Coleoptera: Cleridae: Tillinae) from México and Central America, with notes on others, pp. 519-552 in Zootaxa 3946 (4) on pages 548-549, DOI: 10.11646/zootaxa.3946.4.3, http://zenodo.org/record/23860
Enoclerus skillmani Rifkind, n. sp.
No full textEnoclerus skillmani Rifkind, n. sp. (Fig. 3) Type specimens. Holotype male: Panamá, Bocas d[el] T[oro], 8 ° 33 ' N, 81 ° 48 ' W, Quebrada Gato, 1400 m, 4 Aug. [19] 93, H. Stockwell. Holotype deposited in CSCA. Paratypes: PANAMÁ: 1, same data as holotype; 2, Chiriquí Prov., nr. Mina Cerro Colorado, 8 ° 32 ' N, 81 ° 48 ' W, 6 Aug. [19] 93, el. 1800 m, Gillogly–Stockwell; COSTA RICA: 1. Puntarenas Prov., Monteverde Reserve, 1500 m, 18 –viii– 1987, H. & A. Howden. Paratypes are deposited in USNM and JNRC. Diagnosis. Distinguishable from congeners by virtue of a unique combination of setation, pronotal and elytral sculpturing, and color. From the Costa Rican species E. puravida Rifkind, which it most closely resembles, it can be distinguished by its black legs, smoother pronotal posterior, somewhat more anteriorly situated elytral fascia, and absence of any patch of pale setae on the metasternum; from E. anctus, also from Costa Rica, it can be separated by the shape of its elytral fascia (not constricted or bisected apically), by its overall shinier aspect, by its lack of a concentration of pale setae on the elytral disk, and by the condition of its mesofemora, which are not swollen distally. Other small, black, antlike Enoclerus species in Panamá either bear prominent basal elytral tubercles, or have entirely smooth or distinctly carinate (rather than punctate/rugulose) elytral anterior surfaces. Description (Holotype). Length: 4.30 mm. Color: black; antennal scape and pedicel dark testaceous; mouthparts, trochanters, and coxae reddish; each elytron with a narrow, triangulate, slightly oblique, irregularly margined, raised eburneous fascia, placed anterior to middle; fascia interrupted by epipleuron laterally, and rather broadly internally (Fig. 3). Head: antennae elongate, club loosely composed and gradually expanded from eighth antennomere; surface densely, shallowly and rather coarsely punctate, moderately vested with suberect and erect, mostly silvery setae; width across eyes just slightly narrower than maximum pronotal width. Pronotum: campanulate, longer than broad (4: 3), feebly arcuate at anterior margin, subflattened on disk; transverse impression broadly U–shaped; surface rather finely, shallowly punctulate, shallowly granulate and subrugosely roughened anteriorly and laterally; vestiture composed of mostly long, robust, erect, pale and black setae, most evident laterally, and a moderately sparse but conspicuous array of medium–length, subrecumbent, anteriorly directed white setae that form an indistinct transverse band at middle. Elytra: 2 X as long as wide; widest at posterior 1 / 3, slightly inflated from there posteriorly; basal 1 / 3 of elytra very coarsely, deeply punctate; punctures large, irregularly elongate–faveolate, oriented longitudinally and coalescing into indistinct rows; vestiture sparse and mostly coarse, with a concentration of finer, pale setae along suture; subbasal tumescences shallow, rounded above and produced anteriorly; each elytron bearing a narrow, raised, eburneous, transverse fascia at about anterior 1 / 3; fascia scalloped along margins, expanded laterally where it is interrupted by epipleuron, rather broadly interrupted internally before elytral suture; elytral posterior 2 / 3 shining; integument very obscurely dimpled, rather sparsely set with mostly suberect, medium length, mostly pale, posteriorly directed setae, most conspicuous on posterior 1 / 4; apical slope acute, apices rounded, very slightly dehiscent. Metasternum: shining, moderately convex posteriorly; very sparsely, inconspicuously setose, without a dense patch of pale setae at sides. Legs: elongate, mesofemora not notably expanded distally. Variation. Length of the few available specimens ranges from 3.90 mm to 4.30 mm. They are otherwise rather similar. Etymology. I take pleasure in naming this beetle for Fred W. Skillman, Jr., who has for many years generously made available to me the cleridological bounty of his prodigious collecting efforts. Distribution. Known from the provinces of Bocas del Toro and Chiriquí in Panamá, and the Monteverde Cloud Forest Reserve in Puntarenas Province, Costa Rica. This is apparently a montane species: all specimens were collected between 1400 m and 1800 m elevation.Published as part of Rifkind, Jacques, 2012, New Central American and Mexican Enoclerus Gahan (Coleoptera: Cleridae: Clerinae): Part II, pp. 1-27 in Zootaxa 3397 on pages 4-5, DOI: 10.5281/zenodo.21305

Can be distinguished from the nominotypical subspecies by the complete and broad internal separation of its median elytral fascia. In Enoclerus s. silbermannii (Chevrolat) the fascia is more or less transverse, or at most slightly constricted posteriorly at middle, and always complete internally to suture. In the new subspecies, the fascia is broadly interrupted internally (where it is rounded in contour) and usually somewhat narrowed laterally towards the epipleura, thus taking the form of two ovate maculae. Two specimens from Honduras exhibit a condition that could be interpreted as transitional between the nominate Mexican subspecies and the new subspecies, having the median fascia constricted at the suture both anteriorly and posteriorly, and somewhat infuscate at the sutural margin. These phenotypic differences may represent a north/south geographical cline, but since the Costa Rican and Salvadoran specimens only display the fully separated condition of the elytral fascia, I feel justified in assigning them subspecific status. Description (Holotype). Length: 8.10 mm. Color: black; terminal 3 antennomeres and tarsi dark brown; each elytron with a large, yellowish ovoid macula at middle, complete to lateral margins, incomplete internally well before suture. Head: densely granulate–punctate, densely set with short, suberect, rust–colored setae. Pronotum: convex, about as broad as long, narrower than elytra at base; posterior slope precipitous; transverse impression mostly obscured by vestiture; surface densely granulate–punctate, rather thickly set with suberect rust–colored setae of moderate length, interspersed with a few longer, rust colored and black setae; middle of disk with a large, transverse, ovoid patch of densely arrayed, suberect, black setae. Elytra: elongate (ratio of length to width 7: 4), widest posterior to middle; humeri pronounced; sides sinuate posterior to humeri, broadly, arcuately convergent posterior to middle; apices dehiscent; subbasal tumescences prominent, each crowned with a shining tubercle; surface deeply, coarsely and subconfluently reticulate–punctate anteriorly; punctures a little smaller and more separated at middle; posterior rather finely, shallowly granulate–punctate; vestiture as follows: base set with a thinly arrayed but distinct triangular patch of erect and subrecumbent pale setae of moderate length; pale maculae inconspicuously vested with short, suberect and longer, erect pale setae; posterior 1 / 4 densely covered with subrecumbent pale orange setae, interspersed with a few longer, erect setae of the same hue; other black integument inconspicuously but rather densely covered with mostly short, mostly suberect, black setae. Mesosternum: posterior median process strongly elevated. Metasternum: densely covered with rather long, cinereous pubescence; anterior median process elevated at apex. Abdomen: shining, sparsely pubescent, rather smooth; visible sternite 5 with hind margin slightly arcuately inflexed; visible sternite 6 small, with hind angles rounded, slightly inflexed at middle of posterior margin; visible tergite 6 surpassing sternite 6, sides oblique, hind margin feebly arcuately emarginate, bearing setal daggers. Legs: robust. Variation. Size ranges from 7.70 mm to 11.75 mm. Some specimens have the elytral anterior orangish; one Salvadoran specimen has the elytral apices orange as well. The elytral posterior pubescence ranges from cinereous to pale orange, often with a narrow fringe of rusty setae at its anterior margin. The female has visible sternite 6 and visible tergite 6 with their hind margins conjointly rounded, and lacking setal daggers. Etymology. The subspecific name is Latin for "eternity" or "permanence." Distribution. Known from western El Salvador and northern and central Costa Rica. Biology. This appears to be an upland species: most specimens were taken above 500 m elevation. One example was collected on flowers of Casearia aculeata Jacq.; another was beaten from Aphelandra scabra (Vahl.) Sm. in bloom.Published as part of Rifkind, Jacques, 2012, New Central American and Mexican Enoclerus Gahan (Coleoptera: Cleridae: Clerinae): Part II, pp. 1-27 in Zootaxa 3397 on pages 18-19, DOI: 10.5281/zenodo.21305

Heffern, E. van den Berghe, colls. (TAMU). Description. Length: 6.0 mm. Color: black. Pronotum with dorsal anterior 1/4 and sides rather broadly reddish; elytra with an uninterrupted reddish line extending along lateral margins from umbone to umbone, merging at midelytra into a narrow, feebly arcuate transverse fascia (Fig. 1–2). Head: surface finely, densely punctulate, moderately densely covered with short and medium length suberect silvery setae, and a few long, more robust, black setae; antennae medium length; club distinct, composed of terminal 3 antennomeres. Pronotum: broader than long, subflattened on disk above; anterior depression rather shallow; surface shining, densely, shallowly, granulate punctate, moderately densely but inconspicuously vested with short, suberect, silvery setae, intermixed with longer, more robust, erect, black setae, and posteriorly with long, erect, silvery setae. Elytra: less than 2× as long as broad, humeri prominent, umbones distinct; subbasal tumescences shallow, indistinct; sides subparallel, arcuately convergent posteriorly to conjointly rounded apices; dorsum subflattened; integument densely, shallowly granulate, rather sparsely but uniformly set with fine punctures; vestiture rather dense, composed as follows: anterior 1/2 with a broad scutiform patch comprised of short, fine, adpressed, silvery setae, intermixed with fewer longer, more robust, suberect, black setae; a narrow zone on either side of midelytral fascia composed of short, reclinate, black setae; elytral posterior 1/2 uniformly set with short, fine, adpressed, silvery setae, intermixed with fewer longer, more robust, suberect, black setae. Mesosternum: posterior process shallow. Metasternum: shallowly, finely roughened; sides clothed with medium length, fine, silvery setae. Abdomen: ventrites shining, shallowly dimpled, sparsely clothed with fine, silvery setae; ventrite 5 with hind margin broad, broadly, feebly emarginate; ventrite 6 small, hind margin arcuate; tergite 6 with hind margin conjointly rounded with ventrite 6. Variation. Only the holotype is known. Etymology. The specific epithet is patronymic, honoring Daniel Heffern, collector of the holotype. Distribution. The new species is known only from the holotype locality in Francisco Morazán Province, Honduras. It was collected in June. Natural history. According to Dan Heffern and Eric van den Berghe (personal communication), co-collectors of the holotype, the specimen was captured with an aerial tropics net by sweeping yellow flowers of a leguminaceous tree (Fabaceae). Diagnosis. Enoclerus hefferni can be distinguished from congeners by its unique pronotal and elytral color pattern, and details of its elytral vestiture. It resembles no other described species of Middle American Enoclerus, and its affinities are not apparent.Published as part of Rifkind, Jacques, 2021, Enoclerus hefferni, a new species of checkered beetle (Coleoptera: Cleridae: Clerinae) from Honduras, with additions to the Honduran Enoclerus Gahan fauna, pp. 1-4 in Insecta Mundi 2021 (847) on page 3, DOI: 10.5281/zenodo.504141

Paratypes are deposited in CASC, CIUM, CJSC, CNIN, CSCA, EMEC, FMNH, JNRC, KSUC, LACM, RHTC, SEMC, TAMU, UCRC, and WFBM. Diagnosis. Specimens of Cymatodera from the southern half of México can be reliably assigned to this species if they possess the following combination of characters: integument dark brown, with at most a faintly indicated pale median elytral fascia; 8.0 mm or greater in length; pronotum transversely wrinkled; pubescence fine, short, silvery; elytral punctures serially arranged, obsolete before apices. In addition, the males have a uniquely shaped pygidium (Figs. 5–7) and a distinct pattern of scarlike metasternal carinae (Fig. 8). Females of C. mexicana and C. kolbei are superficially similar, but the latter are generally paler and have the pronotum coarsely, very densely punctate rather than shining and transversely wrinkled. Description. (Holotype). Length: 13.0 mm. Form: elongate; elytra subparallel. Color: dark brown; umbones and an indistinct median elytral band, paler; apical 1 / 2 of antennomere 11 testaceous. Head: shining, densely, very finely punctate, sparsely setose; antennae moderately elongate; antennomeres as follows: 2 slightly shorter than 3; 3 and 4 subequal; 5 slightly longer than 4; 6 and 7 subequal, each slightly shorter than 5; 8 slightly shorter than 7; 9 and 10 subequal, each slightly shorter than 8; 11 elongate-ovate, as long as 10. Pronotum: elongate (ratio of length to width 26: 17), subflattened on disk above; surface shining, rather inconspicuously vested with fine, mostly short, suberect silvery setae; integument distinctly transversely rugulose and very finely, moderately densely but inconspicuously punctate. Elytra: elongate (ratio of length to width 8: 3); humeri weakly rounded; anterior margin broadly V-shaped; sides subparallel, arcuately convergent posteriorly to separately rounded, slightly dehiscent apices; dorsum rather broadly subflattened with a gradual apical slope; integument shining, moderately densely but inconspicuously set with short and slightly longer fine, suberect, silvery setae, these somewhat more densely arranged and conspicuous on posterior 1 / 2; punctures arranged in longitudinal rows, moderately coarse and cribrate anteriorly but progressively finer and more shallow posteriorly until becoming obsolete at posterior 1 / 5; diameter of strial punctures smaller than width of interstrial integument on disk; surface of interstrial area extremely finely punctate. Metaventrite: with a broad, flat, triangulate area at middle, its surface asperate, pustulate and bearing a distinct pattern of scarlike carinae, arranged as in Fig. 8. Abdomen: ventrites 1–4 with surface shallowly, coarsely punctate and wrinkled, posterior margins membranous at middle; ventrite 5 with surface more deeply, distinctly punctate and roughened, sides obliquely convergent, hind margin as in Fig. 6; ventrite 6 with surface very coarsely, irregularly asperate–punctate, bearing a short longitudinal carina at base; shape complex: sides deeply furrowed and flanged, with posterior angle of each flange produced to a short, sharp, triangular point below, and a longer, slightly decurved apically blunted point above (Figs. 5–6); hind margin arcuately emarginate; tergite 6 densely, shallowly, rather coarsely asperate; form elongate, with broadly arcuate sides, posterior margin feebly emarginate (Fig. 5). Aedeagus: apex of phallus upturned. Variation. Length of available specimens ranges from 8.0 mm to 13.75 mm. Some specimens are reddish brown rather than dark brown. The pale median elyral fascia is obsolete in a small minority of examples. The female metaventrite is rugulose, and lacks the asperate sculpturing and carinae of the male. The pygidium of the female appears as follows: ventrite 5 with sides oblique, hind margin rather deeply, semicircularly emarginate; ventrite 6 rather short, with sides feebly convergent, surface slightly tumid anterior to hind margin, hind angles rounded, hind margin feebly, triangularly incised at middle; tergite 6 with sides oblique, hind angles rounded, hind margin slightly inflexed, minutely notched at middle. Etymology. I chose the specific epithet “ mexicana ” as an appropriate descriptor for this most widely distributed Mexican Cymatodera species. Distribution. As the extensive paratype series attests, the new species has been collected in numbers throughout the southern half of México. It is known from the following Mexican states: Michoacán, Colima, Morelos, San Luis Potosí, Estado de México, Guerrero, Puebla and Oaxaca. It will doubtless be found in other Mexican states where there is appropriate habitat. Biology. This species has been taken at light, and beaten from dead limbs and a variety of plants, including Acacia pennatula (Schltdl. & Cham.) Benth., Acacia cochliacantha Humb. & Bonpl. ex Willd., Haematoxylon sp., and Ziziphus amole (Sessé & Moc.) M.C. Johnst. Based on location and other label data, it seems to be associated with thorn forest, tropical deciduous forest and the tropical deciduous forest / oak forest ecotone, and ranges in elevation from near sea level to approximately 1100 m (Fig. 10). A male specimen I captured and photographed alive (Fig. 9) did not stridulate when held in the hand (see Rifkind 2006), but energetically and persistently attempted to “sting” with the downturned pygidium. Remarks. Relationships of the new species are unclear. Like Cymatodera cicatricula (described below), C. mexicana males have a flattened, roughly sculpted metaventrite bearing scarlike carinae; unlike the former, they possess an essentially concolorous, undecorated elytral integument. The new species has a similar habitus to C. tlahuica Rifkind, Toledo & Corona from Morelos and Guerrero, but that species lacks modifications of the metaventrite in the male. Another superficially similar species is C. kolbei, discussed above, but here again the male of that species has the surface of the metaventrite mostly smooth, and quite different pygidial modifications (Figs 1–3). The female of C. kolbei has a more coarsely punctate pronotum than in C. mexicana, and its sixth abdominal ventrite is not tumid basally. The relative phylogenetic significance of these characters must await a more complete descriptive catalog of the genus.Published as part of Rifkind, Jacques, 2015, New species of Cymatodera Gray (Coleoptera: Cleridae: Tillinae) from México and Central America, with notes on others, pp. 519-552 in Zootaxa 3946 (4) on pages 522-525, DOI: 10.11646/zootaxa.3946.4.3, http://zenodo.org/record/23860
