description: Kisaura acuta sp. nov.
(Figs 16–18)
Material examined. Holotype: adult male, India: Uttarakhand; Burnighat, 1400 m, 24-ix-2008, Pandher and Parey, (NPC).
Additional material examined. 1 female, collection data same as of holotype.
Diagnosis. Some broad genitalic characteristics of this species are similar to those of K. venusta Malicky & Chantaramongkol 1993 and K. ophir Malicky & Prommi 2009 (in Malicky 2009), both reported from Thailand. But K. acuta sp. nov. deserves the status of a distinct species as it is the only species so far recorded with a banded pattern on the apical half of each lateral spiniform process and the preanal appendages are uniquely pointed and dagger-like.
Description. Adult male: Color in alcohol brown, maxillary palps pale, wings hyaline yellowish, dorsum of head dark brown, thorax fuscous. Body covered with short fuscous pubescence. Length from tip of head to apices of folded forewings 6.25 mm; antennae each 4 mm long; maxillary palps each 1.50 mm long, segment III longer than II; labial palps each 0.50 mm long. Length of each forewing 5 mm; fork I present, with petiole; discoidal cell more than twice as long as wide; pterostigma prominent. Hind wings each 4.25 mm long; fork I present.
Male genitalia (Figs 16–18). Tergite VIII distal margin incised medially. Segment IX in lateral view quadrate and anterodorsally roundly produced; posterolateral margin nearly straight, anterior margin concave in ventral view. Each inferior appendage 2-segmented: basal segment small, stouter than terminal segment, uniformly wide, with two apical lobes, apicodorsal lobe suboval, broad in lateral view (Fig. 16), apicoventral lobe with tuft of long setae, articulation sclerite bent outward, apicodorsal lobe and small articulation sclerite articulating with base of terminal segment; terminal segment directed nearly dorsad, longer than basal segment, uniformly wide, with row of black comb-like setae on mesal surface visible in both dorsal and ventral views. Tergum X membranous and fused with apex of phallus, reaching apices of basal segments of inferior appendages. Lateral spiniform process and preanal appendage arising on each side of tergum X at base; lateral spiniform process directed cephalad basally then recurved caudoventrad, apical half with peculiar banded pattern, reaching middle of terminal segment of inferior appendage, with articulated spine at tip; preanal appendage rhomboidal, pointed apically dagger-like in lateral and dorsal views (Figs 16, 17), reaching apex of basal segment of inferior appendage. Phallus surrounded by tergum X and with pair of medial spines in lateral view (Fig. 16).
Distribution. India: Uttarakhand.
Etymology. The species is named acuta (Latin adjective) because of the acute apices of the dagger-like preanal appendages.
