Kisaura teestaensis sp. nov. (Figs 1–5) Material examined. Holotype: adult male, India: Sikkim; Singhik, 2600 m, 14-ix-2009, Pandher and Parey (NPC). Paratype. 1 male, collection data same as of holotype. Diagnosis. This species is very similar to K. longaria Mey 1996 and especially Kisaura filiformis Mey 1996 (both reported from Vietnam) as they all have very long lateral spiniform processes of tergum X and finger-like preanal appendages. However, in K. teestaensis tergite VIII is produced posteromedially; the lateral spiniform processes are very long, reaching beyond the apices of the terminal segments of the inferior appendages in both lateral and dorsal views, whereas, in K. filiformis, tergite VIII is not produced posteromedially; and the long lateral spiniform processes do not reach beyond the apices of terminal segments of the inferior appendages. 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 apex of folded forewings about 6.25 mm; each maxillary palp 1.50 mm long, each labial palp 0.50 mm long. Length of each forewing 4.50 mm; venation with fork I absent, discoidal cell about twice as long as wide. Each hind wing about 3.25 mm long, fork I absent. Male genitalia (Figs.1–5). Sternite VIII with small ventral process (Fig. 1); tergite VIII posteromedially produced in dorsal view (Figs 2, 4). Segment IX long, somewhat quadrate, anterodorsally pointed in lateral view (Fig. 1); posterolaterally broad, with shallow excision; posteroventrally slightly produced; in ventral view (Fig. 3) segment IX broad, anterior margin concave, posterior margin invaginated. Inferior appendages each two-segmented: Basal segment longer than terminal one, directed slightly upward, oval, narrow basally, round and broad distally, stouter than terminal segment in lateral view (Fig. 1), with two apical lobes, apicodorsal lobe sub-oval, broad, dorsal margin tapering towards apex; apicoventral lobe with tuft of long setae of nearly uniform width in ventral view (Fig. 3); articulation sclerite directed posterad, broad basally, narrower apically, apicodorsal lobe and small articulation sclerite articulating with base of terminal segment visible in ventral view (Fig. 3); terminal segment directed dorsocaudad, with row of dark brush-like setae on the mesal surface curved in lateral and ventral views (Figs 1, 3). Tergum X membranous and fused with apex of phallus, extending beyond middle of basal segment of inferior appendages (Figs 1, 2). Lateral spiniform process and preanal appendage arising on each side of tergum X at base (Figs 1, 2, 5); each lateral spiniform process directed cephalad basally and then recurved caudad and slightly ventrad, with articulated spinelet at apex, reaching beyond apices of terminal segments of inferior appendages. Preanal appendages as long as segment IX, somewhat bird-head-like in lateral view (Fig. 1) and clavate in dorsal view (Figs 2, 5). Phallus membranous, surrounded by tergum X, having three median spines, two spines arranged dorsally (Fig. 2) and one median spine below them (Fig. 1) visible through tergum X. Distribution. India: Sikkim. Etymology. This species is named after the Teesta River, on the bank of which the type locality in Singhik is located. |
