Pandher, Manpreet Singh & Saini, Malkiat Singh, 2015, Five new species of genus Kisaura Ross (Trichoptera: Philopotamidae) from Himachal Pradesh (India), Zootaxa 4021 (2), pp. 377-386 : 379-384

Kisaura sachensis sp. nov.

( Figs. 11–12 )

Material examined. Holotype male, INDIA: Himachal Pradesh; Traila, 2300 m, 17-vii-2010, Pandher and Parey, deposited in NPC.

Paratypes. Collection data same as of holotype, 2 males.

Diagnosis. This species is allied to K. madhyamika Schmid 1960 , reported from Pakistan, and K. monospinata sp. nov., as both of these species have reduced or rudimentary lateral spiniform processes of tergum X. However, the shape of the preanal appendages is slightly pointed apically and the apical segment of each inferior appendage is rounded apically in lateral view in K. sachensis sp. nov. Moreover, the phallus is very long as compared to other allied species.

Adult male: Body in alcohol fuscous, maxillary and labial palps yellow, dorsum of head and thorax black, wings hyaline light yellow. Body covered with golden yellow pubescence. Length from tip of head to apex of folded forewings 6.75 mm; maxillary palps each 1.75 mm long, segment III longer than II; labial palps each 0.75 mm long. Length of each forewing about 6 mm; fork I present with petiole about half as long as fork; discoidal cell elongate, about twice its width; pterostigma prominent. Hind wings each 4 mm long; fork I present.

Male genitalia ( Figs. 11–12 ): Segment IX reduced to short ring in lateral view. Inferior appendages each 2- segmented; basal segment (coxopodite) small, stouter than apical segment (harpago), oval, with two apicomesal lobes, inferior one with tuft of long setae; apical segment compressed, nearly uniformly wide, long, apically rounded, bearing subdorsal, longitudinal row of black comb-like spines on mesal surface visible in dorsal and ventral views. Tergum X membranous, reaching beyond bases of apical segments of inferior appendages, lateral spiniform processes reduced, indicated by tiny process attached to mesal base of each preanal appendage. Preanal appendages each, wide and truncate in lateral view. Phallus completely surrounded by tergum X and almost indistinguishable from tergum X when in retracted position, with three long, asymmetrical spines.

Distribution. INDIA: Himachal Pradesh.

Etymology. This species is named after Sach pass, which is just above the Traila village from where the type was collected.

Kisaura monospinata sp. nov. ( Figs. 13–14 )

Material examined. Holotype male, INDIA: Himachal Pradesh; Alha, 2200 m, 11-vii-2010, Pandher and Parey, deposited in NPC.

Paratype. Collection data same as of holotype, 1 male, 1 female.

Diagnosis. This species is a member of a group of Kisaura species in which the lateral spiniform processes of tergum X are reduced or rudimentary. It is very similar to K. madhyamika Schmid 1960 from Pakistan. However, the shapes of tergum X and the phallus are very different; tergum X is blunt apically in lateral view and the apical segment of each inferior appendage is oval and long in K. monospinata sp. nov., whereas tergum X and the phallus are slightly pointed apically in lateral view and the apical segment of each inferior appendage is truncate and smaller in K. madhyamika .

Adult male: Body color in alcohol fuscous, wings pale hyaline, antennae, maxillary and labial palps yellow, dorsum of head black. Body covered with golden, short pubescence. Length from tip of head to apex of folded forewings about 7.25 mm; antennae each 5 mm long; maxillary palps each 1.75 mm long, segment III about 1.5 times as long as II, segment V longest; labial palps each 0.75 mm long. Length of each forewing 6.25 mm; fork I present with petiole about 1.5 times length of fork; pterostigma prominent; discoidal cell long, triangular, about 3 times as its width. Hind wings each 5 mm long; fork I present.

Male genitalia ( Figs. 13–14 ): Segment IX short; its anterior margin convex, posteroventrally produced. Inferior appendages each 2-segmented, basal segment (coxopodite) small and stouter than apical (harpago) segment, narrow basally, wide and truncate apically, with two apicomesal lobes, inferior lobe with tuft of long setae; apical segment long, uniformly wide, its superior margin convex with curved row of black comb-like spines on mesal surface visible in ventral and dorsal views. Tergum X membranous, reaching to apices of basal segments of inferior appendages, lateral spiniform processes rudimentary, indicated by small processes below preanal appendages. Preanal appendages each wide, rounded, bluntly angled apicomedially in lateral view; resembling wheat spike in dorsal view. Phallus intimately surrounded by tergum X and almost indistinguishable from tergum X when in retracted position, wide apically, with single long spine at base.

Distribution. INDIA: Himachal Pradesh.

Etymology. The species is named monospinata due to the presence of a single spine at the base of the phallus.

Kisaura curvata sp. nov. ( Figs. 15–18 )

Material examined. Holotype male, INDIA: Himachal Pradesh; Chamba, 1,000 m, 22-v-2008, Pandher, deposited in NPC.

Paratype. Collection data same as of holotype, 1 female.

Diagnosis. This species is very distinct from all other species of this genus as its preanal appendages are curved (twisted at upper middle part) outward in dorsal view.

Adult male: Body color in alcohol brown, legs pale, wings hyaline yellow, dorsum of head dark brown. Length from tip of head to apex of folded forewings about 6 mm; maxillary palps each 1.50 mm long; labial palps each 0.50 mm long. Length of each forewing 5 mm; discoidal cell elongate, twice its width; hind wings each 4.25 mm long, fork I absent in both forewings and hind wings.

Male genitalia ( Figs. 15–18 ): Posterior margin of tergite VIII with median invagination in dorsal view; sternite VIII without ventral process. Segment IX quadrate, with rounded anteromedian margin, anterodorsally not pointed; posterolaterally with small excision; posteroventrally produced. Inferior appendages each 2-segmented, basal segment (coxopodite) slightly longer than apical segment (harpago), basally broad, oval, stouter than apical segment in lateral view, with two apicomesal lobes, its inferior lobe having tuft of long setae; apical segment compressed, directed somewhat dorsad, nearly uniformly wide in lateral view, with curved row of dark brush-like spines on mesal surface in dorsal and ventral views. Tergum X membranous, extending almost to middle of basal segments of inferior appendages, with lateral spiniform process arising on each side at its base, directed cephalad and then recurved caudoventrad, crossing middle of basal segment of corresponding inferior appendages, with articulated spinelet at apex. Preanal appendages, each longer than segment IX, rounded in lateral view and twisted at upper middle part in dorsal view. Phallus membranous, surrounded by tergum X and almost indistinguishable from tergum X when in retracted position, with 2 median spines visible through tergum X.

Distribution. INDIA: Himachal Pradesh.

Etymology. This species is named after its outwardly curved (twisted) preanal appendages.
