Diagnosis. In the presence of a ventral process on sternite VIII and foliaceous preanal appendages, D. punjpullaensis sp. nov. closely resembles D. elongata Kimmins 1955 from Myanmar and D. malickyi sp. nov. However, D. punjpullaensis can be distinguished from D. elongata in that the basal segment of each inferior appendage is about 1.5X as long as the apical segment in D. elongata , whereas it is about 1.25X as long as the apical segment in D. elongata . Apical segment of inferior appendages is much shorter but broader in D. punjpullaensis whereas this segment is long and narrow in D. elongata . Preanal appendages are longer than segment X in D. punjpullaensis whereas these appendages are almost equal to segment X in D. elongata in dorsal view. Moreover, the apices of the lobes of segment X are pointed mesad in D. punjpullaensis but the lobes are smooth in D. elongata . Also, the shape and number of phallic spines clearly separate D. punjpullaensis sp. nov. from allied species.

Description. Adult male: Color in alcohol entirely fuscous except legs fulvous, maxillary and labial palpi yellowish brown. Body covered with inconspicuous, sparse and fuscous pubescence except head with mixture of golden and fulvous setae. Antennae almost equal to length of forewings; length of each forewing 7.5–9.0 mm; apical forks I–V present in each forewing; fork I with petiole about 1.75X as long as fork; discoidal cell somewhat longer than in all other species observed; median cell 1.5X discoidal cell; hind wings each with apical forks I–III and V present and 3 anal veins extending freely to wing margin.

Male genitalia ( Figs. 3–4 & 19 ). Sternite VII without ventral process. Sternite VIII with well developed ventral process. Segment IX reduced to narrow sclerotized band dorsally, anterolateral margins strongly convex and posterolateral margins each with large concavity near its base to accommodate inferior appendages in lateral aspect. Inferior appendages 2-segmented, elongate, in lateral aspect basal segment almost 1.5X as long as apical segment, apical segment broad at its base, having inferior side concave and tapering toward narrow rounded apex, clothed with spinules internally. Segment X gourd-shaped, dorsally with narrow cleft about 1/5th of median length, apices of lobes so formed nearly triangular with pointed inner margins, these lobes projecting slightly obliquely downward in side view and with membranous central area in dorsal view. Preanal appendages foliaceous in side view; slightly incurved, with inner basal margins each produced inward in rounded setose lobe and indented, slender in dorsal view, longer than the segment X and divergent. Phallus large, membranous, cylindrical, pointed apically with following spines: 1 long spine with basal plate, spine curved, almost semicircular and longer than basal plate, no small spines visible in lateral as well as dorsal view.

Etymology. This species is named for its type locality, Punjpulla near Dalhousie.

Distribution. India: Himachal Pradesh, Uttrakhand.
