Diagnosis. This subspecies
D. forficula
is most similar externally to the formerly described one due to the elongate shape and acute apex of forewings, however, these traits appear here in a more extreme form. Head, thorax and forewings are more unicolorous dark fuscous-grey with faint maculation and obsolescent blackish brown crosslines. Abdomen and hindwings are only slightly lighter. The expanse of both sexes are similar (
38–40 mm
).
The male genitalia (
Figs 50, 51
) are generally similar to those of the typical
D. forficula
, the valvae are, however, proportionally more elongate comparing to the relatively short clasper. Vesica projected ventrally and completely returned helicoidally, the subbasal diverticulum bears one or two needle-shaped cornuti.
In the female genitalia, the antrum is relatively weakly sclerotised and the appendix bursae is only slightly shorter and more saccate than the bursa.
Distribution. This subspecies, known in a few specimens only, seems to be confined to certain medium-high altitude areas in the eastern part of the Hindukush range.
Etymology. The name refers to the region of the
type
locality in Northern
Pakistan
.
