Description. Male. Forewing length 15−16 mm. Thorax and abdomen densely covered with grey hairs. Antenna bipectinate, comb length 4−5 times longer than diameter of rod of antenna. Forewing long, with pointed apex, grey, with dense pattern of dark transverse stripes throughout wing margin. Fringe unicolorous grey. Hindwing pale grey with thin undulated bands in submarginal and postdiscal areas. Fringe unicolorous grey.

Male genitalia. Uncus large, with rounded apex curved downwards; tegumen large; gnathos branches thick, short, strongly widened distally; gnathos poorly sclerotized, band-shaped; juxta very large, strongly sclerotized, with pointed abdominal process and long lateral processes with acute apex; valva very wide, strongly concave, proximal 3/4 of valva length sclerotized, distal fourth membranous, area between sclerotized and membranous parts delimited by strong subapical sclerotized ridge which continues into strong sclerotized process at costal margin and sclerotized roll-shaped harpe at dorsal margin; sacculus well developed; transtilla processes pyramid-shaped with wide rounded apices; saccus semispherical, large; phallus slightly shorter than valva, straight, thick, strongly sclerotized, pointed at apex (dorsal margin of phallus) and with two pairs of small tapered cornuti in vesica; vesica aperture in dorso-apical position.

Female slightly larger than male, with length of forewing 17−19 mm. Antenna with a short double-comb. Forewing darker than that of male, with developed dark margins at forewing base and in discal area of costal margin.

Diagnosis. The genus Dervishiya Yakovlev, 2006 was introduced for Cossus cadambae Moore, 1865 (Figs 10−12) (Type locality: Calcutta; distribution: Nepal, Pakistan, India) (Yakovlev 2006). Later D. vartianae Yakovlev, 2011 was described (Figures 13−14) (Type locality: Afgh[anistan]., Nimla, 40 km SW v. Dschelalabad; distribution: Eastern Afghanistan) (Yakovlev 2011). D. sindhi from other species by the features of wings pattern and male genitalia structure: the pale grey forewings of males, thin undulated pattern on the forewing of males, the strong costal ridge with caudally directed process, and the two pairs of tapered cornuti in vesica.
