Pandher, Manpreet Singh, Kaur, Simarjit & Parey, Sajad Hussain, 2020, Review of the genus Kisaura Ross 1956 (Trichoptera: Philopotamidae) from India, Zootaxa 4845 (2), pp. 225-238 : 228-229

Kisaura rotunda sp. nov.

( Figs 6–10 )

Material examined. Holotype: adult male, India: Sikkim; Singhik , 2000 m, 14-ix-2009, Pandher and Parey ( NPC).

Additional material examined. 1 female, collection data same as of holotype.

Diagnosis. This species is similar to Kisaura cina Malicky & Chantaramongkol 1993 reported from Thailand as well as K. intermedia ( Kimmins 1955) . However, in K. rotunda , the posterior margin of tergite VIII is rounded; tergum X and the phallus are not divided at their tips (divided into four parts in K. cina as per original description) and reaching almost to the apices of the basal segments of the inferior appendages; the very long lateral spiniform processes reach the apices of the terminal segments of the inferior appendages; the basal segment of each inferior appendage is slightly longer than the terminal segment; whereas, in K. intermedia , tegite VIII is without produced lobes and the basal segments of the inferior appendages are as long as the terminal segments.

Description. Adult male: Color in alcohol light brown, dorsum of head dark brown, maxillary and labial palps pale yellow. Length from tip of head to apices of folded forewings about 6 mm long, maxillary palps each 1.50 mm long; labial palps each 0.50 mm long. Forewings each 4.50 mm, fork I absent, discoidal cell about twice as long as wide. Hind wings each about 3.25 mm long, fork I absent.

Male genitalia ( Figs. 6–10 ). Sternite VIII without ventral process ( Fig. 6 ); tergite VIII with posterior margin slightly convex in dorsal view ( Figs 7, 9 ). Segment IX elongate, pentagonal, anterodorsally pointed in lateral view ( Fig. 6 ); posterolaterally with shallow excision; posteroventrally produced, in ventral view ( Fig. 8 ) anterior margin broadly concave, posterior margin covering bases of basal segments of inferior appendages. Inferior appendages each two-segmented: Basal segment slightly longer than terminal one, basally round, broad distally, stouter than terminal segment in lateral view ( Fig. 6 ), with two apical lobes: apicodorsal lobe broad, suboval, in lateral view ( Fig. 6 ); apicoventral lobe with tuft of long setae; in ventral view ( Fig. 8 ) broad basally, articulation sclerite directed posterad, slender, but broad at base and visible in ventral view, apicodorsal lobe and small articulation sclerite articulating with terminal segment; terminal segment with row of dark brush-like setae on mesal surface visible in both dorsal and ventral views. Tergum X membranous and fused with apex of phallus, extending to apices of basal segments of inferior appendages; lateral spiniform process and preanal appendage arising on each side of tergum X at base ( Figs 6, 7, 10 ); lateral spiniform process directed cephalad basally and then recurved caudad and slightly ventrad, with articulated spinelet at apex, reaching almost to apices of terminal segments of inferior appendages. Preanal appendages as long as segment IX, somewhat bird-head-like in lateral view and clavate in dorsal view. Phallus membranous, surrounded by tergum X, with single median spine visible in lateral view.

Distribution. India: Sikkim.

Etymology. This species is named ‘rotunda’ because of the slightly convex distal margin of tergite VIII.
