Priocera denticarea Opitz 2021, nov.sp.
No full textPriocera denticarea OPITZ nov.sp. (Figs 41, 93, 127) HOLOTYPE: ♂. Type locality: HONDURAS: Dept. Atlantida, Tela, Lancetilla Botanical Gardens, 28- V-1993, M. C. Thomas (FSCA). PARATYPE: 5 specimens. Honduras: Departamento de Atlantida, Tela, Lancetilla Botanical Gardens, 28-V-1993, M. C. Thomas (CUIC, 1; FSCA, 1; WOPC, 2); idem, 28-V-1993, R. Turnbow (RHTC, 1). D i a g n o s i s: Specimens of this species are similar to those of Priocera stictica GORHAM and P. costaricana WOLCOTT, from which they can only be distinguished by examination of the aedeagus. In P. stictica GORHAM, the phallic plate is set with serrations and in P. costaricana the phallic apex is uncinate. Neither of these phallic characteristics are present in specimens of P. denticarea. D e s c r i p t i o n: Size: Length 8.0 mm; width 2.0 mm. Form: As in Fig. 127. Head: Frons about as wide as length of antennal pedicel (EW /FW 45/10). Thorax: Pronotum finely punctate, with 2 tumescenses (PW /PL 90/145); elytra slightly concave at middle, disc sculptured with striate asetiferous punctures that extend beyond basal 1/2, elytral apex rounded (EL /EW 340/60); metathoracic leg gradually increasing in diameter towards apex. Abdomen: Aedeagus as in Fig. 41. V a r i a t i o n: Size: Length 8.0-9.0 mm; width 2.0- 2.2 mm. Other than body size, the available specimens are quite homogeneous. N a t u r a l h i s t o r y: The available specimens were collected in May. D i s t r i b u t i o n (Fig. 93): This species is known from Honduras. E t y m o l o g y: The trivial name, denticarea, is a Latin compound name that stems from denti (= tooth) and careo (= to be without). I refer to the lack of serrations on the phallic plates.Published as part of Opitz, Weston, 2021, Taxonomic revision of the West ern Hemisphere checkered beetle genus Priocera KIRBY (Coleoptera, Cleridae, Clerinae), pp. 1145-1255 in Linzer biologische Beiträge 52 (2) on pages 1174-1175, DOI: 10.5281/zenodo.503885

Etymology. The specific epithet, acutipennis, is a Latin compound name that stems from acuti (= sharp) and penna (= wing). I refer to the sharply tapered elytral apex.Published as part of Opitz, Weston, 2020, Taxonomic revision of the Western Hemisphere checkered beetle genus Axina Kirby (Coleoptera: Cleridae: Clerinae), pp. 1-70 in Insecta Mundi 2020 (793) on page 38, DOI: 10.5281/zenodo.456494

Pronotum finely punctate, with 2 tumescences, concave at middle; PW/PL 100/123; elytra, few asetiferous punctures, not striate, punctures mostly present in elytral basal ½, width of interstitial spaces variable; EL/EW 410/85. Abdomen. Aedeagus, phallobasic lobes spatulate, widely separated; edge of phallic plates serrate; phallobasic apodeme abbreviated. Variation. Size. Length 8.5–12.0 mm; width 2.0–3.0 mm. Other than body size, the available specimens are quite homogeneous. Natural history. Specimens were collected in Bolivia during October through December, some at altitudes that range from 400–1,025 m. In Peru, they were collected during May, and in Brazil during October. Distribution (for map see Fig. 70). This species is known from Bolivia, Peru, and Brazil. Etymology. The specific epithet, oligocheia, is a Greek compound name that stems from oligo (= few) and cheia (= hole in ground), with reference to the comparatively few asetiferous punctures on the elytral disc.Published as part of Opitz, Weston, 2020, Taxonomic revision of the Western Hemisphere checkered beetle genus Axina Kirby (Coleoptera: Cleridae: Clerinae), pp. 1-70 in Insecta Mundi 2020 (793) on pages 18-19, DOI: 10.5281/zenodo.456494

Axina orcastomata Opitz 2020, new species
No full textAxina orcastomata Opitz, new species Figures 41, 69, 80. Type material. Holotype. Male. Type locality: BOLIVIA: Santa Cruz, Potrerillos del Guenda, 400 m, 6-8/ XII/2011, Morris & Wappes (FSCA). Paratypes. 17 specimens. Bolivia: Departamento de Santa Cruz, Potrerillos del Guenda, 6-8/XII/ 2011, 400 m, Morris & Wappes (RFMC, 2); 3.7 km SSE Buena Vista, Hotel Flora & Fauna, 405 m, 5-15-XI-2011, M. C. Thomas & B. K. Dozier, tropical transitional forest (FSCA, 1). Brazil: Estado do Mato Grosso,?-?-1886, P. Germain (AMNH, 1: BMNH,1; CMNH, 1; MNHN, 5; WOPC, 2); idem,?-?-1885, P. Germain (USNM, 1); Estado do Bahia, Villa Victoria,?-?-1890, Ch. Pujol (MNHN, 1); Estado do Minas Gerais, Pedra Azul,?- XI-1971, F. M. Oliveira (CUIC, 1); idem,?- XII-1970, F. M. Oliveira (SDEI, 1). Diagnosis. In members of this species, the elytral basal castaneous marking is restricted to the humeral angle. This characteristic will distinguish the members of this species from superficially similar specimens of A. lobispinula, in which the castaneous making in question traverses the entire length of the elytral basal margin. Description. Size. Length 9.2 mm; width 2.2 mm. Form. As in Fig. 80. Color. Cranium bicolorous, frons and epicranium light castaneous, remainder dark castaneous; antenna testaceous; thorax black, except center of pronotum disc and pronotum arch light castaneous; elytra bicolorous, mostly flavotestaceous, humerus and epipleural margin widely dark brown, dark brown region extended medially near apex and near elytron middle, preapical brown marking extends towards base near sutural margin; legs bicolorous, distal ½ of femora and proximal ½ of tibiae black, remainder of legs testaceous; abdomen brown. Head. Cranium finely punctate, frons about as wide as length of antennal pedicel; EW/FW 45/18. Thorax. Pronotum finely punctate, with 2 paralateral spheroid tumescences, one narrow linear short tumescence behind middle, disc concave near middle; PW/PL 100/150; elytra, asetiferous punctures scattered, punctures extend posteriorly to elytral 3/4, interstitial spaces very wide; EL/EW 410/60. Abdomen. Female visible abdominal sternite V emarginate; female pygidium with recurved flap; aedeagus (Fig. 41), phallobase abruptly narrowed near base of phallobasic lobes; phallobasic lobes long, narrow; phallic plates not serrate; phallobasic apodeme abbreviated. Variation. Size. Length 8.0–12.0 mm; width 2.0– 2.5 mm. Except for body size, the available specimens are quite homogeneous. Natural history. Specimens were collected in Bolivia during November and December, at altitudes that range from 400– 405 m. During the same months these beetles were captured in Brazil at 800 m. Distribution (for map see Fig. 69). This species is known from Bolivia and Brazil. Etymology. The specific epithet, orcastomata, is a compound name that stems from the Latin orca (= whale) and the Greek stoma (= mouth). I refer to the peculiar construction of the distal 1/3 of the phallobase/phallobasic lobes.Published as part of Opitz, Weston, 2020, Taxonomic revision of the Western Hemisphere checkered beetle genus Axina Kirby (Coleoptera: Cleridae: Clerinae), pp. 1-70 in Insecta Mundi 2020 (793) on page 15, DOI: 10.5281/zenodo.456494
