François Génier & Patrick Arnaud, 2016, Dendropaemon Perty, 1830: taxonomy, systematics and phylogeny of the morphologically most derived phanaeine genus (Coleoptera: Scarabaeidae, Scarabaeinae, Phanaeini), Zootaxa 4099 (1) : 17-18

7. Dendropaemon (Coprophanaeoides) inflatus Génier & Arnaud , new species

( Fig. 7 , 156 )

Type locality. Rio Verde (400m), Goiás, Brasil

Diagnosis. The acutely notched external side of each clypeal tooth will place this species in Coprophanaeoides . Within Coprophanaeoides , the straight clypeal edge between clypeogenal junction and lateral emargination of clypeal teeth combined with the ill-defined elytral striae will separate it from all other species.

Description. Female holotype ( Fig. 7 ). Body. Body moderately large, length 18.0 mm, maximum width 9.5 mm; body subrectangular in dorsal view; dorsum slightly convex. Color. Dorsal surface dark brown to black, glossy, with green metallic sheen; head with green and coppery metallic sheen on posterior portion of clypeus, genae and frons; pronotum with green metallic sheen along margins and most of anterolateral declivities; elytra with faint greenish metallic sheen; ventrum with faint greenish and coppery metallic sheen; pygidium with green metallic sheen; legs with faint coppery sheen. Head. Clypeus gena arcuate, clypeus straight between clypeogenal junction and lateral emargination of clypeal teeth, anterior portion upturned; clypeal teeth ogival; clypeal median emargination narrowly v-shaped, clypeal edge acutely notched on external side of each clypeal tooth, clypeal teeth ventral surface lacking carina, clypeal margin ill-defined, bordered posteriorly by a more or less regular row of punctures, clypeal surface with transverse blunt rugulae; clypeogenal suture well-defined, bluntly carinate internally on anterior half; genal surface with fine tubercles anteriorly and minutely punctate posteriorly, lacking distinct transverse carina, flat; clypeofrontal carina low, more than 6 times wider than high, straight in dorsal view, simply carinate, clypeofrontal carina apical edge straight in frontal view; eyes small in dorsal view, interocular ratio 4.2. Pronotum. Pronotum transverse in dorsal view, pronotal width/length ratio 1.4; disc of pronotum minutely punctate basally, puncture becoming fine anteriorly and changing into fine isolated rugose tubercles on declivities, with an ill-defined shallow longitudinal depression on posterior half; pronotal anterior margin only slightly wider and flat lateral to eye; anterior portion with a simple anteriorly arcuate carina; anterior angles surface finely granulate, similar to lateral margin along posterior edge of anterior margin; lateral fossae ill-defined, bordered laterally by a sharp carina and anteriorly by a rather acute tubercle; lateral portions strongly explanate; pronotal basal fossae ill-defined, slightly concave; posterior margin well-defined, lacking crenulation and setae. Elytra. Elytra approximately as long as wide in dorsal view, elytral combined width/length ratio 1.2; elytral base distinctly marginate; elytral striae 1–4 fine and ill-defined, evenly impressed throughout, elytral striae 5 similar to 4 on disc, strial punctures minute, stria 1 weakly impressed apically, going straight to elytral apical margin; interstriae slightly convex, minutely punctate throughout, surface glossy. Thoracic sterna. Proepisternal carina absent; metasternal median lobe angularly produced anteromedially, ventral ridge well-defined, y-shaped. Legs. Profemur posterior surface slightly but distinctly convex and glabrous internally, posterointernal margin rather thin, uneven, internal edge rather wide, with a contiguous row of setae along anterointernal edge and few scattered long setae on anterior half, remaining surface smooth. Protibia with four teeth on lateral edge; internal basal angle lobate; anterior surface with long aligned row of setae internally, surface glossy or feebly microsculptured between punctures; posterior surface with rugose irregular punctures externally to median carina, surface finely and irregularly microsculptured between punctures, with a single interrupted setal row along lateral teeth. Mesofemur angularly produced on anterointernal edge apically. Mesotibia rather slender, gradually widening toward apex in anterior view; anteroapical edge slightly sinuate in anterior view, anteroapical row of setae complete; apicoanterior edge circularly indented internally; external edge more or less rounded, with several large elongate setiferous punctures. Mesotarsus similar in shape to metatarsus, 3-segmented, first segment short, approximately as long as wide at apex. Metafemur elongate, internal and lateral edges mostly parallel in ventral view, more than twice as long as wide, lacking distinct depressed area anterointernally before apex, apicoposterior edge unmodified, anterior surface with a well-defined sulcus on more than half the length. Metatibia rather slender, gradually widening toward apex in anterior view, anterior surface with distinct row of setae, with moderately dense minute punctures on a glossy surface, metatibial posterior surface flat between longitudinal row of setae and lateral edge, glossy between punctures. Metatarsus 3-segmented, first segment moderately elongate, approximately two times as long as wide at apex, with anterointernal carina well defined and almost reaching apical edge. Abdominal sternites. Sternites 3–6 longitudinally flat; sternites 4–6 with 1–3 unaligned rows of setae laterally, glabrous medially; sternite 7 approximately longitudinally flat medially, subequal in length to segment 6 along midline; pygidium minutely punctate on disc.
