Hydropsyche kangra Oláh & Barnard , new species

Fig. 168–172

This species is close to H. kaznakovi Martynov from Tadzhikistan. The new species is separated from H. kaznakovi by the presence of a parallel-sided, not triangular median keel on segment IX; a wide interlobular gap on segment X; the dorsum of phallotheca being concave and subapically curving dorsad; the phallotremal sclerites that are longer than the ventral sclerous lobe of phallotheca; and the endophallus that is attached to the dorsum of the phallotheca. Like all known species in the H. pluvialis species group, except H. kaznakovi , this species has a free endophallus running slightly dorsad forming a narrow tube unattached to the dorsum of the endotheca.

Male. Large, body and wings brown with light pubescence. Forewing membranes almost uniformly brown, only with indistinct, pale dots. Maxillary palp formula I-II-(III, IV)-V, segment V as long as segments I–IV together. Dorsum of head dark brown, with 9 paler warts. Swollen setal wart present on proepisternum. Pretarsal claws asymmetrical, laterally flanked by setal bundle. Spur formula 244. Both protibiae with posteroapical spur smaller than anteroapical spur.

Wings. Venation typical for the genus. Forewing crossveins m-cu and cu separate. Sc and R, and Cu2 and A run separately before costa. Hind wing Sc and R meeting before costa about at crossvein r. Stem of M and Cu1 running closely. Median cell closed. Fork 1 present. Forewing length 13.0 mm, hind wing length 9.0 mm.

Male genitalia. Abdominal segment IX fused annularly, moderately long; median keel long, parallel-sided in dorsal view ( Fig. 169); dorsal surface granulose; lateral surfaces flat, glabrous; anterior margin arciform, with short dorsum and half as long ventrum ( Fig. 168). Antecosta on lateral sides well developed, forming double line narrowing dorsally before margin; with well developed external groove of antecostal suture ( Fig. 168). Apical lobe on posterolateral margins broadly triangular ( Fig. 168). Both posterior spine rows continuous, except for short area at dorsum of apical lobes and on dorsum. Depression between segments IX and X deeply V-shaped. Dorsal margin of segment X short, ventral margin long ( Fig. 168); rounded triangular in lateral view; quadrangular in dorsal view ( Fig. 169); slightly constricting basally. Lateral setose areas (preanal appendages) forming compact, pale pigmented and elliptical surfaces centrally on lateral surfaces, and more distally located, loosely packed, groups of setae. Apicoventral setose lobes modified into pair of short, digitiform processes; very short and directed ventrad ( Fig. 168). Dorsal interlobular gap deep, wide. Apicodorsal setose lobes forming sharply triangular fused setose ridges or crests dominating dorsum in lateral view ( Fig. 168). Glabrous, smooth, shallow cavity present on segment X. Short, wide, darkly pigmented, transverse suture present on both sides originating from bottom of intersegmental depression, forming dark suture crossing central part of segment X in dorsal view ( Fig. 169). Longitudinal suture above each lateral setose areas running along and parallel with ventral margin of segment X. Coxopodites slightly exceeding apex of segment X ( Fig. 168); dorsal margin slightly sinuous at basal half; dilating from mid-length; straight in ventral view ( Fig. 170). Harpagones straight in lateral view, curving mesad in ventral view ( Fig. 170); cylindrical along their length. Phallic apparatus simply bent ( Fig. 171); flat basis shortened, curving ventrad. Phallotheca with concave dorsal margin, apex dilating. Endophallus attached to dorsal wall of phallotheca, reaching over phallic apparatus bend. Phallotremal sclerites falciform; broad in lateral view; reaching apex of sclerous, ventral phallothecal lobe. Pair of sclerous, broad and narrowing endothecal processes originating laterally of phallotremal sclerites. Sclerous, ventral process of phallotheca shorter than phallotremal sclerites, simple, with rounded apical margin in ventral view ( Fig. 172).
