Type locality. Awaran , Khuzdar District, Pakistan.

Diagnosis. Male and female pronotal anteromedian tubercle similar, well developed, simply round in lateral view (Fig. 90); pronotal anterior median longitudinal sulcus wide and deep ( Figs. 56 , 89).

Description. Holotype ♂ ( Fig. 8 ). Measurements. Length 15.5 mm, width 9.0 mm. Head ( Figs. 25–26 ). Anterior clypeal edge straight on median fifth in dorsal view; clypeofrontal carina broadly arcuate and interrupted at gena; vertex with a median acute conical process approximately as high as wide, surface with rather dense, irregular granules. Horns long, strongly divergent on basal half in frontal view, gradually tapering from base to apex, posterointernal edge unmodified basally, internal surface with a few small, scattered granules. Genal edge slightly upturned and arcuate on anterior third, forming a broad angle with clypeal edge. Pronotum ( Fig. 56 ). Surface with granulate punctures extending slightly beyond posterior half, lacking simply umbilicate punctures; punctures smaller posterolaterally, with distinct minute punctures throughout. Anteromedian tubercle well developed, forming a simply convex projection in lateral view; surface of tubercles covered with rather regular and fine scabrous granules; median longitudinal sulcus very wide and deep. Surface behind the eyes with a small and shallow round depression, surface of anterior angles sloping laterally; anterior half of lateral edge sinuous in dorsal and lateral view; posterior angles produced into a obliquely oriented tooth in dorsal view; anterior hypomeral ridge broadly arcuate anteriorly with anterior most portion crenulate, anterior hypomeral depression surface darker in color. Elytra ( Fig. 8 ). Intervals 2 and 4 with irregularly scattered, fine granules from base to apex. Legs. Protibial apicointernal tooth enlarged, with dorsal ridge extending to apex. Aedeagus ( Fig. 120 ). Parameres with dorsal and ventral edges diverging toward apex in lateral view. Internal sac sclerites ( Figs. 138–140 ). Axial sclerite strongly sclerotized, abruptly bent ventrally on apical third. Subaxial sclerite, extending straight past apex of right lateral fold apical portion, with villi on apical half. Frontolateral peripheral sclerite basoventral apophysis moderately developed; two medioventral carinae present; right lateral fold produced into a rather large everted and open apically conical process with extremely irregular apical edge; left lateral lobe absent; subapicodorsal lobe membranous, narrow, not reaching anterior edge, apex set medially in dorsal view; apical lobe round and directed obliquely on left side, apical villi regular in shape; subapicoventral lobe short not reaching apical edge of apical lobe, oriented obliquely and in line with ventrally folded left edge of apical lobe.

Variation. Measurements (14 ♂♂, 36 ♀♀). Length: male 11.5–16.5 mm (14.5 ± 1.5 mm), female 11.5–17.0 mm (14.7 ± 1.1 mm). Female allotype. Cephalic outline in dorsal view as in Fig. 72 ; vertex with horns wide basally and regularly tapering to apex, posterointernal edge lacking acute tooth basally; anterior pronotal configuration (Figs. 89–90) similar to male. Protibia short, with external teeth more robust.

Etymology. Uks (ox) is a Sanskrit noun in apposition for bull, pertaining to the aspect of the cephalic horns in this species.

Natural history. The specimens collected in Iran are from pastures, no other data.

Remarks. In addition to the characters given in the description, the pronotal color pattern slightly differs by having the pale edging posterior portion less sharply defined medially, with the dark discal coloration extending further posteriorly compared to D. bonasus .
