Pandher, Manpreet Singh & Saini, Malkiat Singh, 2014, New additions to the genus Kisaura Ross (Trichoptera: Philopotamidae) from the Indian Himalaya, Zootaxa 3793 (5), pp. 538-544 : 541

Kisaura golitarensis sp. nov.

( Figs. 5–8 )

Material examined. Holotype ♂. INDIA: Sikkim: Golitar, 2,200 m, 26-iv-2009, Pandher and Parey, deposited in NPC.

Paratypes: Collection data same as those of holotype, 1 ♂.

Other material examined. 1♀ (tentatively associated by similarities in wing venation).

Diagnosis. This species is very distinct from other species of this genus recorded from India due to the peculiar shape of the lateral spiniform processes, which are trifid apically, i.e., each has an apical spinelet and two other apical processes of the same length ( Fig. 8 ).

Adult male: General color in alcohol yellowish brown, head dark brown, thorax shining brown, wings and legs yellowish brown. Body covered with inconspicuous, sparse, light brown pubescence. Length of each antenna 5 mm; maxillary palps relatively short, each only 1.0 mm long, segment III slightly longer than II and sub-equal to IV, segment V almost twice IV; labial palps very short, each 0.5 mm long. Length of each forewing 6.25 mm, its discoidal cell relatively small; pterostigma not prominent in fore- and hindwings; apical fork I absent in both wings.

Male genitalia ( Figs. 5–8 ): Tergite VIII with shallow V-shaped notch at middle of distal margin; sternite VIII with small posteroventral process. Segment IX in lateral view quadrilateral, dorsally and anterolaterally straight, anterodorsally elongate and acute, posterolaterally concave, posteroventrally with prominent projection. Inferior appendages each 2-segmented; basal segment almost as long as apical segment, narrow at base and broad toward apex with two lobes, of which superior lobe unadorned and inferior lobe with tuft of long and stout setae; apical segment broad basally and rounded and narrow apically, mesal surface with long and stout basal spine and curved longitudinal row of long spines clearly visible in dorsal and ventral views. Tergum X membranous, extending almost to distal margin of segment IX, lateral spiniform process arising on each side at its base, recurved anterad and then caudoventrad, reaching to apex of basal segment of its corresponding inferior appendage, with articulated spinelet at apex and two other apical processes of same length. Preanal appendages almost equal to segment IX, each with apex blunt in lateral view and its inner margin serrate in dorsal view. Phallus membranous, intimately surrounded by tergum X and having blunt apex, scarcely distinguishable from tergum X when phallus in retracted position.

Distribution. INDIA: Sikkim.

Etymology. The species name pertains to its type locality Golitar.
