Type depository: holotype in NMPC , paratypes No. 1–12 in RSCV , paratypes No. 13–14 in MCSN . Description of holotype (male). Body length 13.1 mm , elongate, almost parallel-sided, strongly convex. Dorsal and ventral surfaces dull; head dark brown; pronotum pale brown, with yellow apical corner; elytra pale brown with darker suture and humeral umbones with pale, scale-like macrosetation ( Fig. 1A ). Dorsal surface of head, pronotum, scutellum, and elytra covered only with white, wide, recumbent, scale-like macrosetae; ventral surface of thorax and abdomen covered with white, wide, recumbent, scale-like macrosetae and with sparse, shorter, recumbent reddish-yellow macrosetae. Mouthparts, antennae, and legs covered with reddish-yellow, moderately long macrosetae. FIGURE 1A–L. Entyposis cordipenis Sehnal , new species , holotype male (A–E, I, J) and paratype female (F, G, H, K, L). A–B, G–H, habitus, dorsal and lateral views; C–D, aedeagus, dorsal and lateral views; E–F, inner protarsal claw; I–J, K–L, pronotum, dorsal and lateral views. Scale bar = 1 mm. Head with labrum transverse, deeply bilobed; lobes rounded, irregularly and weakly punctate; lobes covered with long, erect macrosetae. Head including clypeus smooth, glossy, fissured, densely coarsely punctate; each puncture with a semierect macroseta 2x longer than puncture diameter. Frontoclypeal carina broadly arcuate; surface behind carina densely but unevenly punctate except a narrow impunctate strip adjacent to frontoclypeal suture. Frontoclypeal suture curved, medially arched toward occipital carina. Occipital carina always present, prominent. Space posterior of frontoclypeal suture with a large impunctate area. Occiput sparsely, evenly, moderately punctate. Canthus narrow, short, with sparse long macrosetae. Width of both eyes combined approximately equal to maximum width of frons between eyes, eye distinctly extending beyond canthus. Antenna with 10 antennomeres; club with three antennomeres, almost straight, shorter than antennal shaft (antennomeres 1–7 combined). Antennomeres 1–7 with sparse, long macrosetae; club with sparse, short macrosetae. Terminal maxillary palpomere expanded apically, 1/3 shorter than palpomeres 2 and 3 combined. Pronotum transverse, widest behind middle; with a shallow, oval anteromedial depression narrower than head that weakly rises toward edge of crest. Anterior margin turned forward, medially elevated, extended into a columnal impunctate summit, laterally diminishing ( Fig. 1A–B, I–J ), with angles extended forward. Lateral margins crenulate and macrosetose. Posterior margin bordered, shallowly arched medially, with smooth margin paralleled by a row of coarse punctures and hind angles broadly rounded. Crest delimiting anteromedial depression prominent, with a wide V-shaped strip, at summit of crest impunctate. Depression densely covered by shallow, asperate punctures with setae 2x longer than puncture diameters. Punctation of remaining surface also shallow and irregular; setae yellow, scale-like, somewhat recumbent. Scutellum large, broadly triangular, sides and apex rounded; with circular punctures; each puncture bearing a short, narrow, white, scale-like, semirecumbent macroseta. Elytra weakly convex, parallel-sided, rounded apically; apical angle approximately rectangular. Striae absent except for a feeble sutural stria. Humeral umbones present, weakly swollen, impunctate, without scale-like macrosetae. Surface not microsculptured, moderately shiny; punctures shallow, regularly spaced, separated by 2 puncture diameters. Each puncture bearing a narrow, scale-like, semirecumbent yellow macroseta 3x longer than puncture diameter. Epipleuron distinct, complete, narrow, glabrous laterally. Macropterous. Legs with femora narrow, shiny, irregularly punctate, macrosetaceous. Protibia narrow, distinctly tridentate; terminal tooth inserted above medial spine. Mesotibia and metatibia slightly expanded distally, each with one incomplete longitudinal macrosetiferous carina. Upper terminal spur of metatibia flattened, slightly curved, acute apically 1/3 longer than lower, apically trunctate, chisel-shaped spur. Claws bifid, with ventrobasal teeth and entire ventral edge of lower claw finely serrate ( Figs. 1E ). Ventral surface covered by long, semierect, white macrosetae. Pygidium slightly transverse, convex, completely bordered, apically broadly rounded, irregularly covered by coarse, umbilicate, macrosetiferous, scale-like punctures. Male genitalia ( Figs. 1C–D ). Parameres symmetrical, longer than phallobase, regularly curved with a double hump apically in lateral aspect and a double apex in dorsal aspect; each paramere medially with apex rotated toward base, together forming a heart shape; covered by short, fine, semierect, yellow macrosetae. Variability in males. Paratypes somewhat variable in body length ( 11.5–13.8 mm , n = 11), slightly variable in dorsal punctation density and length and distribution of macrosetae. Sexual dimorphism . Females differ from male in the following characters: body length 11.8–13.8 mm ( Fig. 1G–H ), metatibia more strongly expanded distally; tarsomeres of all legs shorter. Geographic distribution . Ethiopia , Southern Nations , Nationalities and Peoples’ region: Turmi, Machi, and Oromia region : Arero. Differential diagnosis . Entyposis cordipenis Sehnal , new species is distinguished from all species of the genus using the following diagnostic characters in males: entire dorsal surface bearing only scale-like setae; pronotal crest delimiting anteromedial depression prominent, with a wide V-shaped strip, summit of crest impunctate ( Fig. 2A–B ); front margin turned forward, medially elevated, extended into a columnal impunctate summit, laterally diminishing, with yellow angles extended forward ( Fig. 1I –J ) and male genitalia with each paramere apex rotated medially toward base, together forming a heart shape ( Fig. 1C–D ). Etymology . Derived from medial rotation of paramere apices, which together form a heart shape. This name should be treated as an adjective in the nominative singular.
