( Figs. 11–12 & 17–18 )

Holotype 3: INDIA: Himachal Pradesh: Punjpulla, 2,100 m, 20-vi-2011, Pandher, deposited in ( PUPM). Paratype: Collection data same as of holotype, 1Ƥ, deposited in PUPM.

Diagnosis. This species is distinct and allied to Dolophilodes elongata Kimmins 1955 , D. punjpullaensis sp. nov. and D. morsei sp. nov in the presence of a ventral process on sternite VIII. However, it can be clearly distinguished from these species by the shape of segment IX, preanal appendages are much broader and the subapicomesal margins of segment X processes are concave in dorsal view whereas the preanal appendages are almost digitate and the subapicomesal margins of segment X processes are nearly straight or convex in its allied species. Moreover the structure and number of phallic spines clearly distinguishes this species from allied ones.

Description. Adult male: Color in alcohol brownish white, antenna dark brown, longer than forewing, head black, thorax brownish black, maxillary and labial palpi pale. Body covered with inconspicuous, sparse and pale pubescence. Length of each forewing 6.79 mm; each forewing with forks I–V present, fork I with petiole almost 2X as long as fork; discoidal cell well developed; median cell almost 2X as long as discoidal cell; hindwings each with forks I–III and V present; 3 anal veins extending freely to wing margin.

Male genitalia ( Figs. 11–12 & 17–18 ). Sternite VII without ventral process. Sternite VIII with well developed ventral process. Segment IX reduced to narrow sclerotized band dorsally; middle of each anterolateral margin convex, dorsal aspect oblique, posterolateral margins each with large concavity near base to accommodate inferior appendages. Inferior appendages each 2-segmented, elongate, basal segment more than 1.5X as long as apical segment, somewhat concave medially on dorsal and ventral margins; apical segment broad at base in lateral view, ventral margin concave, dorsal margin convex near base, tapering and narrowing to rounded apex. Segment X swollen dorsally, narrowed centrally, and bifid apically in dorsal view, apices of lobes so formed nearly triangular with pointed inner edges, subapicomesal margins concave; lobes projecting obliquely downward, pointed apically in lateral view. Preanal appendages each foliaceous in dorsal view, broad and rounded dorsally, setose in lateral view, longer than segment X and divergent. Phallus large, membranous, with following spines: Longer spine with basal plate, this basal plate more than half as long as spine; pair of anterior spines visible in lateral view, with curved anterior margins in dorsal view; one small semicircular spine also visible posterior to basal plate in dorsal view.

Etymology. This species is named in honour of Dr. Hans Malicky for his contribution to caddisfly systematics.

Distribution. India: Himachal Pradesh.
