Hydropsyche mizora Oláh & Schefter , new species

Fig. 108–112

This species is morphologically similar to H. assarakos Malicky & Chantaramongkol, 2000 from Nepal. Hydropsyche mizora is distinguished from H. assarakos in the shape of the intersegmental depression, being vertical, not oblique; and the apical lobe on segment IX is short, not long. The apicodorsal setose lobe is oriented vertically, not oblique apically; the apicoventral setose process strongly curves ventrad in lateral view, and mesally separate in dorsal view. The phallotremal tongue is slightly S-shaped distally in ventral view and the basis surrounding the 2 partite phallotrema is more robust in lateral view.

Male. Body and wings brown, with faint, darker maculation. Sternum V with low protuberance. Forewing membrane uniformly brown, without pattern. Maxillary palp formula I-II-(III, IV)-V, segment V as long as segments I–IV together. Head dorsum brown, with 9 brown setal warts. Swollen setal wart present on proepisternum. Pretarsal claw asymmetrical, laterally flanked by setal bundle. Spur formula 244. Posteroapical spur on first tibia smaller than anteroapical spur.

Wings. Venation typical for the genus. Forewing crossveins m-cu and cu separate. Sc and R, and Cu2 and A running separately before costa. Hind wing Sc and R tangential before costa about at crossvein r. Stem of M and Cu1 close. Median cell closed. Fork 1 present. Forewing length 7.5 mm. Hind wing unknown.

Male genitalia. Abdominal segment IX fused annularly, short. Median keel unusually broad ( Fig. 109); dorsal surface granulose, lateral surfaces smooth glabrous; keel forming entire dorsum of segment IX, shifted posterad. Anterior margins of segment IX arciform, forming short ventrum and long dorsum ( Fig. 108). Each antecosta well developed, forming double line narrowing dorsad before margins, with external grooves of antecostal sutures. Apical lobe on posterolateral margins rounded triangular ( Fig. 108). Posterior spine row intermittent, weakly developed, present on lower part of median keel slope and on apical lobe ( Fig. 108), absent between. Depression between segments IX and X very short, deep; delineated by distal end of keel and vertical apicodorsal setose process. Body of segment X short; triangular in lateral view ( Fig. 108); rounded quadrangular in dorsal view ( Fig. 109). Lateral setose areas (preanal appendages) located at distal part of segment X, forming compact patch with pale background and distal, scattered setae fringing distal margin ( Fig. 108). Apicoventral setose lobes modified into pair of long, slender processes with apical setae; slightly curving ventrad in lateral view ( Fig. 108); in dorsal view slightly incurving mesally with separate apices ( Fig. 109). Dorsal interlobular gap wide, almost circular, encircled by apicoventral setose lobes; anterior base of gap small, rounded. Apicodorsal setose lobes forming pair of mesal, finger-like, short processes, located immediately posteriorly of intersegmental depression. Smooth cavity on segment forming shallow depression dominating basal half of segment X. Longitudinal sutures encircling ventral part of cavity. Coxopodites not reaching apex of segment X ( Fig. 108); basal half dorsally sinuous, dilating from mid-length. Harpagones each with very broad at short basis ( Fig. 108); distal part long, filiform. In ventral view ( Fig. 110) slightly curving mesad. Phallic apparatus simply bent, broadening along ventrad curving basis ( Fig. 111). Phallothecal dorsum slightly concave. Endophallus forming well-pigmented narrow tube, reaching bend of gonopore ( Fig. 111), distally ending in centre of phallotremal sclerite. Basis of phallotremal tongue two-partite in lateral view ( Fig. 111); distal elongation more slender than membranous apical lobes of endotheca; distal half S-shaped in ventral view ( Fig. 112). Falciform, sclerotized spine on dorsolateral membranous endothecal process long.
