    Deltochilum acanthus Kohlmann & Solís, new species Figs. 6, 7, 15 Diagnosis. This species is distinguished from other Costa Rican Deltochilum species by the following combination of characters: Pygidium with apex thickened, very acutely angled (90 °) and outwardly produced (Fig. 7 f). Apical half of metatibia bent inward. Description. Holotype. Male (Fig. 6): Length 11.9 mm. Humeral width 8.0 mm. Body color black, head and pronotum distinctly punctate. Head approximately as long as wide; clypeus with two distinct, narrowly separated, upwardly reflexed, pointed teeth, pointed anterior teeth; each clypeal-genal margin with low obtuse teeth; vertex closely punctate, nearly flat; dorsal eyes large. Pronotum with lateral margin angulate at middle, otherwise straight to slightly sinuate before and behind; pronotal surface densely punctate, giving the appearance of a honeycomb. Elytral striae indicated by a double line, line expanded by widely separated, shallow strial punctures; disc intervals opaque, with numerous shallow, very close punctures (Fig. 7 h); humeral umbone and apices of third to seventh intervals carinate; elytral surface shagreened. Epipleural upper carina interrupted (Figs. 7 b, d). Pygidium with apex thickened, very acutely angled and outwardly produced (Fig. 7 f); disc nearly flat, shallowly and densely punctate, punctures umbilical. First abdominal sternite forms a rearward projection at the middle of the posterior border. Profemur with margin unmodified; protibia with three apical teeth (the middle one smaller) and numerous serrations on outer margin. Apical half of metatibia bent inwardly. Allotype. Female. Length 11.2 mm. Humeral width 7.6 mm. Similar to male, but the first abdominal sternite is evenly arched at the middle of the posterior border. Variation. Fifty-eight specimens examined, 38 males and 20 females. Length 10.4–13.0 mm. Humeral width 7.3–8.0 mm. Examined material (58 specimens). Holotype, male: COSTA RICA. Prov. Puntarenas. Res. Biol.

The species has been collected with flight interception traps in tropical rain forest, ranging from 0– 100 m altitude, during the months of April to November. Geographical distribution (Fig. 15). This species is known so far from the Pacific rain forest of Costa Rica and the Canal Zone of Panama. Chorological affinities. Deltochilum acanthus seems to show a geographic vicariant pattern in relation to the similar species D. valgum acropyge, which inhabits the Caribbean slope of Costa Rica. Taxonomic relationships. It would appear that the new species originated from a vicariant event, when the Talamanca range rose up approximately 3 million years ago, isolating the rain forest on the Pacific coast from the rainforests on the Caribbean coast. This mechanism seems to account for the origin of a great number of other animal vicariant species, examined in Kohlmann & Wilkinson (2007). We believe that D. valgum needs to be studied, and that its different subspecies represent a species complex in need of hierarchical revaluation. We therefore describe D. acanthus as a species and not as a subspecies, in anticipation of this process. Deltochilum acanthus can be easily separated from D. valgum by its pygidium, which has the thickened apex, very acutely angled and outwardly produced (Fig. 7 f), whereas D. valgum has a much less thickened and projected pygidium (Fig. 7 e). There are also differences in dorsal punctation: the pronotum in D. acanthus is very densely punctured, producing the effect of a honeycomb, whereas in D. valgum the punctures are more spaced, by at least the length of one puncture. The elytral punctures are also different, in D. acanthus punctation is dense and the elytral striae are broad (Fig. 7 h), whereas D. valgum is less densely punctured and the striae are thin (Fig. 7 g). Etymology. Acanthus (ĸανθοζ = acanthos), a Latinized Greek noun in apposition, meaning thorn, making reference to the spiny pygidial apex.Published as part of Kohlmann, Bert & Solís, Ángel, 2012, New species and revalidations of scarab beetles (Coleoptera: Geotrupidae: Athyreini and Coleoptera: Scarabaeidae: Scarabaeinae) from Costa Rica and Panama, pp. 28-52 in Zootaxa 3193 on pages 36-38, DOI: 10.5281/zenodo.21112

    <i>Canthidium margaritae</i> Kohlmann & Solís sp. nov. (Figs. 1–3) <p> <b>Diagnosis.</b> This species is distinguished by the following combination of characters: body globose; head and pronotum uniformly and strongly punctate; frons swollen; frontoclypeal region with a small, smooth swelling medial to each eye; eye dorsally at posterior end of gena narrow, eight to ten facets wide, interocular distance separated by approximately 8–10 times maximal eye width; basal pronotal border not margined; elytra with eight striae, surface lightly shagreened, microsculpture coarser towards apex; hind wing brachypterous.</p> <p> <b>Description of Holotype.</b> Male. Length: 4.5 mm, humeral width: 2.9 mm. Body form globose (Fig. 1). Head and pronotum coppery­red, elytra dark brown (Fig.1). Head and pronotum strongly punctate and devoid of setae.</p> <p>Clypeus rugosely punctate, apex strongly bidentate, median emargination broadly Vshaped (Fig. 2 a); eye dorsally at posterior end of gena narrow, eight to ten facets wide, eyes separated by approximately 8–10 times maximum eye width (Fig. 2 a). Frons and vertex of head strongly punctate, frons swollen; two small, black, smooth swellings between eyes (Fig. 2 a).</p> <p>Pronotum on disc and posterior angles slightly shagreened; surface strongly and uniformly punctate; lateral fovea oval; posterior margin lacking elongated punctures or groove.</p> <p>Elytral striae consisting of clear indented lines interrupted by fairly evenly spaced oval punctures (approximately the maximum length of one puncture); intervals shiny, finely punctate; surface shiny and slightly shagreened especially towards apex. Elytra globose; hindwing brachypterous (Fig. 2 h).</p> <p>Pygidium distinctly punctate, more coarsely so in basal half, surface shiny and slightly shagreened at base. Genitalia as in Fig. 2 g.</p> <p>Protibia with three teeth on external border (Fig. 2c), inner apical margin of protibia produced into a rounded anterior projection and slightly bent downwards (Fig. 2c), apical spur with incurved apex (Fig. 2c). Pro­, meso­ and metafemora with ventral surface finely punctate and finely shagreened.</p> <p> <b>Allotype.</b> Female. Length: 4.6 mm, humeral width: 3.1 mm. Differing from male in the following major characters: clypeus slightly more transversely rugose (Fig. 2 b), apical spur not forming incurved apex and claw­bearing protarsus not as thick (Fig. 2 d), pygidium broader and less heavily punctate (Fig. 2 f), last abdominal segment broader, inner apex of protibia not forming a rounded lobe (Fig. 2 d).</p> <p> <b>Variation.</b> Elytral surface can range from completely shagreened to shagreened only on the apical third.</p> <p> <b>Material examined</b> (8 specimens). <b>Holotype</b> male: MÉXICO.

They are both globose in body shape and brachypterous, they also have a swollen frons, clearly punctate pronotum, shagreened elytra, evenly impressed striae, and they both inhabit cloud forests. This species pair apparently represents a vicariant speciation event between the Sierra Madre del Sur (<i>C</i>. <i>riverai</i>) and the Neovolcanic Axis (<i>C</i>. <i>margaritae</i>).</p> <p> <i>C. margaritae</i> will key to <i>C. riverai</i> Kohlmann and Solís in couplet 12 in the Kohlmann and Solís (2006) key for the <i>Canthidium</i> of Mexico. The two species are very similiar, but <i>C. margaritae</i> can be easily separated from <i>C. riverai</i> by having bigger eyes (8–10 eye facets versus 2–3 eye facets), head and pronotal punctures less coarse, elytra less shagreened, a different metatibial form (internal apical angle projected like a tapering rectangle versus apically obliquely truncated), and differences in the form of the parameres (parameres taper evenly towards apex versus parameres with a small hump at apical two­thirds).</p> <p> <b>Etymology.</b> We dedicate this species to Margarita Castillo, who has always supported Luis Leonardo Delgado in his entomological studies and also helped collect this new species. The name is derived from the latinized (<i>margarita</i>) Greek word μαργαρίτη, meaning a pearl.</p>Published as part of <i>Kohlmann, Bert & Solís, Ángel, 2006, New species of dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) from Mexico and Costa Rica, pp. 61-68 in Zootaxa 1302</i> on pages 62-65, DOI: <a href="http://zenodo.org/record/173658">10.5281/zenodo.173658</a&gt
