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 : 230

Kisaura sangtam sp. nov.

( Figs 11–15 )

Material examined. Holotype: adult male, India: Nagaland; Pfutsero , 2200 m, 08-v-2010, Pandher and Parey, ( NPC).

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

Diagnosis. Due to the presence of a broad (outstanding) segment IX and long terminal segment of each inferior appendage, Kisaura sangtam sp. nov. is similar to Kisaura peleg Malicky & Laudee 2009 (in Malicky 2009) reported from Thailand. However, K. sangtam has long lateral spiniform processes reaching beyond the apices of the basal segments of the inferior appendages, and beak-like preanal appeadages; in contrast, the lateral spiniform processes are small (just crossing the bases of the basal segments of the inferior appenadages) and the preanal appenadages are bird-head-like in K. peleg .

Description. Adult male: Color in alcohol black, legs pale yellow, wings yellowish brown, dorsum of head black. Length from tip of head to apices of folded forewings about 8 mm; maxillary palps each 1.75 mm long; labial palps each 0.75 mm long. Length of each forewing about 6.75 mm; discoidal cell 3 times its width, fork I present with petiole about 1.5 times as long as fork I; hind wings each about 5 mm long, fork I present.

Male genitalia ( Figs 11–15 ). Sternite VIII without any ventral process ( Figs 11, 13 ); tergite VIII with pointed posterolateral and anterolateral edges ( Figs 11, 13 ). Segment IX rather short, trapezoidal, anterodorsally produced in lateral view ( Fig. 11 ), posterolaterally with rounded excision; posteroventrally produced, in ventral view ( Fig. 13 ) anterior margin concave, posterior margin covering basal parts of inferior appendages. Inferior appendages each two-segmented, basal segment small, oval, narrow basally, round and broad distally, stouter than terminal segment in lateral view ( Fig. 11 ), with two apical lobes: apicodorsal lobe broad, rounded apically, apicoventral lobe with tuft of long setae; in ventral view ( Fig. 13 ) broad basally, articulation sclerite broad at base, apicodorsal lobe and small articulation sclerite articulating with base of terminal segment; terminal segment long, slender, with row of dark brush-like setae on mesal surface visible in dorsal and ventral views ( Figs 12, 13 ). Tergum X membranous and fused with apex of phallus, extending beyond apices of basal segments of inferior appendages. Lateral spiniform process and preanal appendage arising on each side of tergum X at base ( Figs 11, 12, 15 ); lateral spiniform process directed cephalad basally and then recurved caudoventrad, with articulated spinelet at apex, reaching middle of terminal segment of inferior appendages; preanal appendage not reaching beyond segment IX, beakshaped in lateral view and clavate in dorsal view. Phallus membranous, surrounded by tergum X, with pair of pointed spines visible through tergum X.

Distribution. India: Nagaland.

Etymology. This species is named sangtam (noun in apposition) after the naga tribe ‘ Sangtam ’ which dominates the type district.
