Pandher, Manpreet Singh, Kaur, Simarjit & Parey, Sajad H., 2018, Three new species of the genus Kisaura Ross (1956) (Trichoptera: Philopotamidae) from Arunachal Pradesh, India, Zootaxa 4403 (3), pp. 586-593 : 589

Kisaura vikrami sp. n.

( Figs. 5–8 )

Material Examined. Holotype: male, India: Arunachal Pradesh; Dirang , 1700 m, 27°20'0"N, 92°16'0"E, 06-x- 2010, Parey & Vikram, deposited in NPC. Paratypes: 1 ♂, 1 ♀, same collection data as holotype .

Diagnosis. This species is very similar to Kisaura filiformis Mey 1996 , reported from Vietnam, due to the presence of long lateral spiniform processes of tergum X. However, tergum X+phallus reaches just beyond mid length (but not to the apex) of the basal segments of the inferior appendages in K. vikrami . In contrast, tergum X+phallus almost reaches the apex of the basal segments of the inferior appendages in lateral view in K. filiformis . The preanal appendages of K. vikrami are blunt apically and extend only to the dorsal apex of sternum IX, but those of K. filiformis are tapered to a blunt end and extend to the ventral apex of the oblique posterior margin of sternum IX. The basal segment of each inferior appendage is clavate apically in K. vikrami in lateral view, but parallel-sided in K. filiformis .

Description. Adult male; color in alcohol dark brown, wings yellow hyaline, antennae infuscated, dorsum of head dark. Length from tip of head to apex of folded forewings 6.25 mm; maxillary palps each 1.25 mm long; labial palps each 0.50 mm long. Length of each forewing about 5 mm; fork I absent, discoidal cell twice as long as wide; hind wings each 4.25 mm long; fork I absent.

Male genitalia ( Figs. 5–8 ). Sternite VIII with prominent apicoventral process; tergite VIII with posterior margin medially excised and with small triangular point in dorsal view ( Fig. 6 ). Segment IX long, in lateral view subrectangular, each side with small anteromedian prominence, acute anterodorsal point; posterodorsal and posterolateral excisions; prominently produced posteroventrally in lateral view. Inferior appendages each twosegmented: basal segment longer than terminal one, clavate in lateral view, with two apical lobes, smaller ventromesal lobe with tuft of long setae; terminal segment directed apicodorsad, parallel-sided in lateral view, with curved row of dark, long brush- like setae on mesal surface. Tergum X membranous, extending to middle of basal segments of inferior appendages, pair of lateral spiniform processes arising at its base on each side, each with articulated spinelet at apex; spiniform processes directed cephalad basally and then recurved apicoventrad and reaching almost to apex of terminal segment of inferior appendages in lateral view. Preanal appendages reaching to dorsal apex of segment IX but not ventral apex, apically expanded and rounded in lateral view and elliptical in dorsal view. Phallus membranous, enveloped by tergum X, with 2 median spines visible through tergum X in lateral view.

Distribution. India: Arunachal Pradesh.

Etymology. This species is named for my colleague Vikram Singh who collected the type specimens.
