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 : 589-592

Kisaura sainii sp. n.

( Figs.9–12 )

Material examined. Holotype: male, India: Arunachal Pradesh; Lumla , 2300 m, 27°54'44"N, 91°72'91"E, 07-x- 2010, Parey & Vikram,, deposited in NPC . Paratype. 1 ♀ (presumed to be the same species), same collection data as holotype.

Diagnosis. This species is similar to Kisaura vikrami sp. n., K. longispina Kimmins 1955 ( Myanmar, Thailand and Vietnam), and K. filiformis ( Bhutan, Thaliand and Vietnam), in the very long segment IX and lateral spiniform processes of tergum X. However, the two U-shaped excisions on the distal margin of tergum VIII and quadrangular segment IX in K. saini sp.n. make it distinct from all these species. The distal margin of tergum VIII is without such excisions in all three species. Segment VIII has its apicodorsal margin medially excised with a triangular point in dorsal view in K. vikrami sp. n.; segment VIII has a uniformly rounded distal margin in K. filiformis , and from lateral view segment VIII appears to have a rounded apex with a pair of slightly rounded subdorsal lobes distally in K. longispina . The basal segments of the inferior appendages are each oval in K. sainii in lateral view, versus clavate in K. vikrami and subrectangular in K. longispina and K. filiformis .

Description. Adult male; body color in alcohol dark brown, dorsum of head dark brown, maxillary palps yellow, wings brown, legs pale yellow. Length from tip of head to apices of folded forewings about 6.50 mm; maxillary palps each 1.50 mm; labial palps each 0.50 mm long. Length of each forewing about 5 mm; discoidal cell elongate, twice as long as wide, fork I absent; hind wings each about 3.75 mm long, fork I absent.

Male genitalia ( Figs. 9–12 ). Sternite VIII without ventral process; posterior margin of tergite VIII with pair of U shaped excisions on the apicomesal margin in dorsal view ( Fig. 10 ). Segment IX long, quadrangular, each side with anteromedian prominence, anterodorsally slightly pointed; posterolaterally with shallow excision. Inferior appendages, each two-segmented, basal segment almost equal to terminal one, elliptical and stouter than terminal segment in lateral view, with two apical lobes, small ventromesal lobe with tuft of long setae; terminal segment with curved row of dark brush-like spines on mesal surface, nearly parallel-sided and thicker basally in lateral view. Tergum X membranous, extending to apices of basal segments of inferior appendages, pair of lateral spiniform processes arising at its base on each side, each spiniform process with articulated spinelet at apex, directed cephalad basally and then recurved caudoventrad, reaching middle of terminal segments of inferior appendages in lateral view. Preanal appendages, each nearly as long as segment IX, slender, clavate, and apically blunt in dorsal and lateral views. Phallus membranous, completely surrounded by tergum X, having 3 median spines visible through tergum X in lateral view, apically notched medially.

Distribution. India: Arunachal Pradesh.

Etymology. This species is named in honor of my mentor, Dr. Malkiat Singh Saini, for his contributions to Insect Taxonomy.
