http://zoobank.org/urn:lsid:zoobank.org:act:D66876EF-FA95-493B-B87B-1D88858C8406 (Figs. 11, 31–32, 59, 75, 95–96, 123, 147–149, 187; Map 6)
Type locality. Toulfé (13°53’33”N 01°53’39”W), 325 m, Loroum, Burkina Faso.
Diagnosis. Species distributed from Oman westward; left lateral apophysis of FLP sclerite large (Fig. 147).
Description. Holotype ♂ (Fig. 11). Measurements. Length 11.5 mm, width 6.5 mm. Head (Figs. 31–32). Anterior clypeal edge straight on median fourth in dorsal view; clypeofrontal carina broadly arcuate and interrupted at gena. Vertex lacking median tubercle; surface with punctures moderate, scabrous anteriorly, separated by less than a diameter. Horns moderately long, parallel on apical half in frontal view, parallel sided on basal four-fifths, slightly tapering externally before apex; posterointernal edge produced into a low, angular projection; apicointernal surface lacking granules, with a few small scabrous punctures; genal edge upturned and distinctly angulate on anterior third, forming a broad angle with clypeal edge. Pronotum (Fig. 59). Surface with granulate punctures restricted to anterior half medially, with smaller, irregularly-scattered, simple punctures on posterior half of disc; punctures lacking posterolaterally, with more-or-less distinct minute punctures throughout; anteromedian tubercle atrophied, simply round in lateral view, median longitudinal sulcus well defined; surface behind the eyes slightly concave, surface of anterior angles concave, anterior angles unmodified; anterior half of lateral edge arcuate in dorsal and slightly sinuous anteriorly in lateral view; posterior angles simply arcuate in dorsal view. Anterior hypomeral ridge straight, abruptly curved before anterior angle, anterior hypomeral depression surface light in color medially. Elytra (Fig. 11). Intervals 2 and 4 with few fine granules on apical declivity only. Legs. Protibial apicointernal tooth enlarged, with dorsal ridge extending to apex. Aedeagus (Fig. 123). Parameres with dorsal and ventral edges slightly diverging toward apex in lateral view. Internal sac sclerites (Figs. 147–149). Axial sclerite moderately sclerotized, shorter than subaxial sclerite and almost straight. Subaxial sclerite, larger basally and abruptly tapering in line with apex of axial sclerite, extending straight and interrupted approximately at apex of frontolateral peripheral sclerite apical portion, with fine villi on apical sixth. Frontolateral peripheral sclerite basoventral apophysis moderately developed, angular in lateral view; with a single acute medioventral carinae; right lateral fold produced into a uneven bifurcate process, lateral edge straight; left lateral apophysis present, large; left lateral lobe absent; subapicodorsal lobe well sclerotized, entirely covering apical lobe, with villi much shorter than apical lobe villi, right edge obliquely truncated before apex; apical lobe truncated apically, apical villi regular in shape; subapicoventral lobe atrophied, oriented ventrally
Variation. Measurements (107 ♂♂, 118 ♀♀). Length: male 7.0– 12.5 mm (10.4 ± 1.0 mm), female 8.0– 12.5 mm (10.6 ± 1.0 mm). Female allotype. Cephalic outline in dorsal view as in Fig. 75; vertex with a broadly arcuate transverse carina, dorsal edge straight in frontal view, lateral portion subangular and sloping down posteriorly; anterior pronotal tubercles well developed, external lateral edges rather strongly widening in dorsal view (Fig. 95), anterolateral surface deeply, obliquely concave, anterosuperior edge slightly arcuate in dorsal view, lateral portion of anterosuperior edge slightly upturned (Fig. 96). Protibia short, with external teeth more robust.
