Description.

Male genitalia. Uncus short, rectangular, anterior margin rounded. Gnathos asymmetrical, proximal part laminar, distal arm finger-like, apex rounded. Tegumen triangular. Phallus twice as long as tegumen, cylindrical, apex forked. Juxta almost as long as uncus, base narrow, apex broadened. Valvae two-thirds length of phallus, inwardly curved, apices asymmetrical, base quandrangular. Vinculum half as long as valvae, margin rounded. S8 triangular, apex bifid, with the points divergent and inwardly curved, and a deep, triangular notch at proximal margin. T8 unmodified, membranous.
Variation.
At present the species is known only from the male
holotype
.
Etymology.
The species was named after the Greek word
drepáne
(= sickle), in reference to the shape of the valvae.
Remarks.
The Kabul Gorge (or Tang-I-Gharoo) is located about
25 km
from Kabul, on the road to Jalalabad and Peshawar.
