Type locality. Ouarsangueli [=Warsangeli Sultanate], Somalia.

Diagnosis. Male cephalic horns with coarse granules internally at apex ( Fig. 52View FIGURES 47 – 54. 47, 49, 51, 53); males with pronotal anterior angles surface deeply concave, simply round anteriorly ( Fig. 51View FIGURES 47 – 54. 47, 49, 51, 53); FLP sclerite ventral portion with a single carinae ( Fig. 179View FIGURES 171 – 182); SA sclerite apex interrupted much before apex of apical portion of FLP sclerite ( Figs. 177–178View FIGURES 171 – 182).

Description. Holotype ♂ ( Fig. 21View FIGURES 19 – 22). Measurements. Length 13.5 mm, width 8.0 mm. Head ( Figs. 51–52View FIGURES 47 – 54. 47, 49, 51, 53). Anterior clypeal edge sinuous on median seventh in dorsal view; clypeofrontal carina broadly arcuate and interrupted at gena; vertex lacking median tubercle, surface with fine and minute punctures; fine, simple punctures separated by one to three diameters. Horns rather long, arcuate and slightly divergent in frontal view apical third more abruptly curved internally, parallel sided on basal two-thirds, and tapering into a point on apical third; posterointernal edge unmodified, internal surface with numerous coarse granules; genal edge upturned and simply arcuate, almost in line with clypeal edge. Pronotum ( Fig. 69View FIGURES 63 – 70). Surface with rather small, granulate punctures restricted to anterior half medially, with smaller scattered simple or slightly scabrous punctures on posterior half of disc; punctures scattered and obsolete posterolaterally, with minute punctures throughout. Anteromedian tubercle well developed, produced into small acute denticle on each side of midline; median longitudinal sulcus deep; surface behind the eyes concave, surface of anterior angles with a deeply concave, anterior angles unmodified; anterior half of lateral edge arcuate in dorsal view and slightly sinuous in lateral view; posterior angles slightly lobate in dorsal view. Anterior hypomeral ridge nearly straight posteriorly and strongly arcuate on anterior third, anterior hypomeral depression surface slightly darker in color medially. Elytra ( Fig. 21View FIGURES 19 – 22). Intervals 2 and 4 with odd, fine granules on apical declivity only. Legs. Protibial apicointernal tooth enlarged, with dorsal ridge extending to apex. Aedeagus ( Fig. 133View FIGURES 119 – 134). Parameres with dorsal and ventral edges diverging toward apex in lateral view. Internal sac sclerites ( Figs. 177–179View FIGURES 171 – 182). Axial sclerite strongly sclerotized, abruptly bent ventrally on apical third. Subaxial sclerite, extending straight and interrupted in line with right lateral fold apical portion, with villi on apical third. Frontolateral peripheral sclerite basoventral apophysis moderately developed; a single medioventral carina present, carina distinctly folded and angulate in ventral view; right lateral fold produced into a large everted and open apically conical process with sinuous apical edge located behind oblique right lateral edge of apical lobe; left lateral lobe well sclerotized; subapicodorsal lobe membranous, narrow, not reaching anterior edge, apex set medially in dorsal view; apical lobe truncate apically and approximately in line with the axis frontolateral peripheral sclerite, ventral portion produced into and additional fold separating two concavities, ventral portion of additional lobe more-or-less parallel to apex of ventral portion of apical lobe, apical villi regular in shape; subapicoventral lobe small, not reaching apical edge of apical lobe, oriented ventrally and in line with ventrally folded left edge of apical lobe.

Variation. Measurements (96 ♂♂, 92 ♀♀). Length: male 9.0– 13.5 mm (11.7 ± 0.9 mm), female 8.0–13.0 mm (11.1 ± 1.0 mm). Female allotype. Cephalic outline in dorsal view as in Fig. 85View FIGURES 79 – 86; vertex with a broadly arcuate, transverse carina, dorsal edge broadly arcuate in frontal view, lateral portion gradually sloping down posteriorly; anterior pronotal tubercles well developed, external lateral edges parallel sided in dorsal view, anterolateral surface simply convex, anterosuperior edge arcuate in dorsal view (Fig. 115), lateral portion of anterosuperior edge slightly upturned (Fig. 116). Protibia short, with external teeth more robust.
