Sortosa obrussa Ross 1956: 57 (original designation).

Spurs: 2, 4, 4; wings with primitive venation except fork I variable: it may be near or considerably beyond sectorial cross vein s, or R₂ may be atrophied and 2A of forewing incomplete (Ross 1956). Male genitalia with pair of lateral processes between Xth tergite and preanal appendages; inferior appendages simple, with mesoventral plate developed between two segments; apical segment of inferior appendage with diagnostic longitudinal row of spine-like setae on its inside mesal surface.

Oriental and Palaearctic Regions.

The genus Kisaura can be easily separated from Dolophilodes Ulmer by a pair of elongate and sclerotized lateral processes of segment X and by the brush-like row of dark setae on the inner surface of apical segment of the inferior appendages which are lacking in Dolophilodes.

In superficial comparison, this species seems somewhat allied to Kisaura moselyi Kimmins, 1955 from North East Myanmar, but the combination of characters, including segment VIII with a deep median V-shaped indentation, clavate preanal appendages, and basal part of the apical segment of the inferior appendage with a stout spine like setae, sets Kisaura clavata sp. n. apart from Kisaura moselyi.

Adult. Color in alcohol entirely fulvous except mesoscutellum flavid; maxillary palp with pale annulations at the joints; head with golden and fulvous pubescence; antenna moderately long, scape:pedicel ratio = 1.66: 1; maxillary palp segments ratios 1: 2: 3: 4: 5 = 1: 2.4: 2.6 : 2.6: 5.3; labial palp segments ratios 1: 2: 3 = 1: 1.75: 3.1. Length of forewing 7 mm, sprinkled with white patches along the posterior margin and covered with moderate, sparse and brownish setae, pterostigma not prominent in both wings; discoidal cell very small in forewing; fork I absent in both wing.

Male Genitalia (Figs 1–5). Sternum VIII without ventral process; tergum VIII with deep median V-shaped zone of spines. Segment IX rather short, sclerotized, quadrate with median prominence on anterolateral side, posterolaterally with shallow, rounded excision, apically setose. Inferior appendages two-segmented; basal segment (coxopodite) little longer and stouter than apical segment (harpago), narrow at its base, broad and rounded towards apex, in lateral view, with two lobes, inferior lobe with tuft of long setae; apical segment with curved row of dark brush-like setae and stout spine-like setae at base on mesal surface in dorsal view. Tergum X membranous, extending beyond apex of segment IX, at base on each side arises blade-like, lateral spiniform process, with articulated spinelet at apex, recurved cephalad and then caudoventrad, reaching up to apex of segment IX. Preanal appendage as long as spiniform process of tergum X and clavate at apex. Phallus membranous, intimately surrounded by tergum X.

Because of the club-like, (i.e., clavate) apex of preanal appendage, this species has been named clavata.

This species is allied to Kisaura sura Malicky & Chantaramongkol, 1993 and Kisaura consagia Malicky & Chantaramongkol, 1993, both reported from Thailand, because of the presence of bilobed preanal appendages. However, Kisaura elongata is sufficiently distinct from these two species as the two lobes are unequal, i.e., one lobe of the preanal appendage is long while the second is very small, and also in having elongate and inwardly recurved lateral spiniform process of tergum X. In Kisaura sura and Kisaura consagia the two lobes of preanal appendage are almost equal and the lateral spiniform process of tergum X is not inwardly recurved.

Adult. Color in alcohol entirely fulvous excepting antenna with dark brown annulation at joints; body covered with moderate, sparse and fuscous setae excepting head with nigrescent pubescence. Antenna almost equal to length of forewing; scape:pedicel ratio = 1: 0.58; maxillary palp segments ratios 1: 2: 3: 4: 5 = 1: 2: 2.6: 1.6: 4.3 and labial palps segments ratios 1: 2: 3 = 1: 0.8: 1.8. Length of forewing 6 mm, sprinkled with yellow patches, in both wings pterostigma not prominent; discoidal cell almost triangular; apical fork I present in both wings, in forewing positioned considerably beyond sectorial cross-vein s.

Male Genitalia (Figs 6–10). Sternum VIII without ventral process, tergum VIII not indented, posterior margin widely excised with V-shaped mark dorsally. Segment IX sclerotized, short, anterolaterally much produced, posterodorsal corner rounded. Inferior appendages long and stout, basal segment (coxopodite) as long as apical segment (harpago), basal segment with small lobe on proximal end of superior side in lateral view, and distally bilobed with inferior lobe bearing long tuft of setae; apical segment curved upright and pointed apically in lateral view, with curved row of black comb-like setae on inner surface in dorsal view. Tergum X membranous, with long inwardly recurved or bent backward, broad ribbon-like lateral spiniform processes which are pointed apically. Preanal appendages long, with two lobes of unequal size, larger lobe thumb-like while smaller wart-like in lateral view. Phallus membranous, surrounded by tergum X.

This species name pertains to excessively long lateral spiniform process of segment X of male genitalia.

This species is close to Kisaura longispina Kimmins 1955 in having a very long lateral spiniform process of tergum X. It also resembles Kisaura intermedia Kimmins 1955 in the shape of the preanal appendages. In Kisaura eloct sp.n. segment IX is much shorter, but wider and the basal segment (coxopodite) of the inferior appendage is long, narrow basally, and broad and truncate apically in lateral view. In Kisaura longispina segment X is long and somewhat quadrate posterodorsally, and the basal segment of the inferior appendage is small, but uniformly wide in lateral view. Kisaura intermedia differsin having the lateral spiniform process of tergum X narrow basally, broad towards its apex, and pointed apically, and also in having the superior side of the basal segment of the inferior appendage convex in lateral view whereas in Kisaura eloct sp. n. the lateral spiniform process of tergum X is almost uniformly wide except with a pointed apex and the basal segment is without any convexity on its superior side in lateral view.

Adult. Color in alcohol entirely fulvous, except mesoscutellum flavid; maxillary palps with pale annulations at their joints. Body covered with dense and fuscous setae except head with fulvous pubescence. Antenna long, scape:pedicel ratio= 1: 0.6; maxillary palp segments ratios 1: 2: 3: 4: 5 = 1: 1.5: 2: 1.2: 2.5 and labial palp segments ratios 1: 2: 3 = 1: 0.75: 1.75. Length of forewing 7 mm; forewing with long discoidal cell; apical fork I absent in both fore- and hind wings.

Male Genitalia (Figs 11–15).Ventral process absent on sternum VIII, tergum VIII with diamond-shaped lobe medially on dorsal surface, with two small incurved depressions on posterior margin. Segment IX sclerotized, long, trapezoidal, stout in lateral view, with posterodorsal margin slightly setose and postventrally produced apically; anterior margin covered partially by sternum VIII. Inferior appendage with basal segment (coxopodite) stout, about as long as apical, narrow at base, broad and bilobed apically in lateral view, inferior lobe with long tuft of setae; apical segment (harpago) curved upwards, with curved row of strong black brush-like setae on inner surface in dorsal view, pointed apically. Tergum X short, narrow, membranous, with pair of long lateral spiniform processes placed medially, extending almost to middle of apical segment of inferior appendage in dorsal view. Preanal appendages narrow, finger-like, scarcely dilated apically, slightly longer than segment IX in lateral view. Phallus tubular, membranous, apparently fused dorsally with membranous tergum X.

This species name is based on an arbitrary combination of letters (i.e., Entomology Laboratory of Caddisfly Taxonomy - “eloct").

This species is close to Kisaura rossi Kimmins, 1955 from North East Myanmar, based on similarities in the shape of the preanal appendages in dorsal view. In Kisaura rossi segment IX is very short, quadrate in lateral view and the preanal appendages are not twisted at mid- length, but preapically twisted. In Kisaura gangtokensis sp. n. segment IX is long, trapezoidal in lateral view, and the preanal appendages are twisted at mid length.

Adult.Color in alcohol entirely fulvous and covered with moderate, fuscous setae excepting head with golden and fulvous pubescence. Antenna long, scape: pedicel ratio = 1: 0.5; maxillary palp segments ratios 1: 2: 3: 4: 5 = 1: 1.3: 2.6: 2.1: 5; labial palp segments ratios 1: 2: 3= 1: 1.5: 2. Length of forewing 7.5 mm; discoidal cell small, apical fork I lacking in both wings.

Male genitalia (Figs 16–19).Sternum VIII without ventral process; tergum VIII roundly produced dorsomesally. Segment IXsclerotized, long, trapezoidal in lateral view, anterodorsally pointed at apex, posteroventrally much produced. Inferior appendages short, stout and two-segmented, both segments subequal in length, basal segment narrow basally, with convex superior and inferior margins, apically bilobed, inferior lobe with long tuft of setae; apical segment vertically upright, its superior margin almost straight, inferior margin convex, rounded apically, mesally with black brush-like setae. Tergum X membranous, intimately surrounding phallus, lateral spiniform process blade-like, long, almost reaching posterodorsal margin of IX in lateral view, with spinelet at apex. Preanal appendagesas long as lateral spiniform process in dorsal view twisted at mid-length, broad and rounded apically. Phallus membranous, fused dorsally with tergum X.

In superficial comparison Kisaura himachalica sp. n. is allied to Kisaura rossi Kimmins and Kisaura cina Malicky & Chantaramongkol, 1993. However Kisaura himachalica is distinct as segment IX is long, the basal segment of the inferior appendage is almost oval in shape, and the preanal appendage is knob-like in dorsal view. In Kisaura rossi segment IX is small, the basal segment of the inferior appendage is quadrate, and thr preanal appendage is twisted preapically and not knob-shaped. The new species also differs in the shape of segment IX, which is broader, and the preanal appendages, which are bilobed and clavate in dorsal view in Kisaura cina.

Adult. Color in alcohol uniformly fulvous and body covered with inconspicuous, sparse and fulvous setae excepting mesoscutellum where is golden. Antenna long, scape:pedicel ratio = 1: 0.7; maxillary palp segments ratios 1: 2: 3: 4: 5 = 1: 1.5: 2.5: 2: 5; labial palp segments ratios 1: 2: 3= 1:1.2: 1.75. Forewing with golden irrorations; length of forewing 7 mm, dicoidal cell small, apical fork I lacking in both wings.

Male genitalia (Figs 20–24).Ventral process absent on sternum VIII; tergum VIII with apical margin produced into two small triangular extensions, separated by shallow excision, area between the two lobes slightly elevated. Segment IX roughly quadrate, anterodorsally pointed, anteromedially with excision, posterodorsally rounded. Inferior appendage with basal segment equal in length to apical segment but stouter than the later, roughly oval in shape, superior and inferior sides convex, divided into two lobes, inferior one with path of long setae, apical segment slender, incurved, with curved row of stout black comb-like setae on inner surface in dorsal view. Tergum X membranous with pair of sword-like lateral spiniform process, about as long as segment IX. Preanal appendage as long as segment IX, clavate in lateral view, apically bulbous and setose in dorsal view. Phallus tubular, membranous, apparently surrounded by Tergum X.

India, Himachal Pradesh.

This species is named after the state in which the holotype was found, Himachal Pradesh.

This species resembles Kisaura gangtokensis sp. n., based on the ratio of the lengths of the lateral spiniform process and preanal appendages, but differs in several aspects: the preanal appendages are long and slender, segment IX is broad anterolaterally and without rounded lobes at the posterolateral end, and the basal segment of the inferior appendage is long and the apical segment is directed upright and truncate apically.

Adult. Color in alcohol entirely fulvous excepting fuscous mesoscutellum. Antenna almost 1.2 × longer than forewing, scape:pedicel ratio = 1: 0.46; maxillary palp segments ratios 1: 2: 3: 4: 5= 1: 2.6: 3.3: 2.6: 5.6; labial palp segments ratios 1: 2: 3= 1: 1: 2. Forewing with white spots and covered with moderate and short setae; length of forewing 9 mm; discoidal cell small, triangular; apical fork I absent in both wings.

Male genitalia (Figs 25–29). Sternite VIII without ventral process, tergite VIII indented dorsomesally, with rounded median lobe. Segment IX long and broad, roughly pentagonal, anterodorsally with pointed median prominence in lateral view. Inferior appendage two-segmented, basal segment convex on lateral margin, broader, bilobed at apex with short inferior lobe and bearing tuft of long setae; apical segment nearly as long as basal segment, narrower, with curved row of spines, rounded at apex in dorsal view. Tergite X membranous, almost reaching apex of basal segment of inferior appendage, with lateral spiniform processes extending beyond apical margin of segment IX, with spinelet at apex. Preanal appendage almost equal to lateral spiniform process, rounded apically in lateral view. Phallus membranous and fused with tergite X.
