82 J. Oláh RHYACOPHILIDAE Himalopsyche todma SCHMID, 1963 - Pakistan: Kashmir, Bubin, lower area, 17.VIII. 2001. leg. B. BENEDEK & G. RONKAY (2 males, 1 female). Kashmir, Deosai Mts, Bubin, 3300 m, 14.VIII.2001, leg. B. BENEDEK & G. RONKAY (2 males, 1 female). Rhyacophila akutila sp. n. (Figs 23-26) Description - Male (in alcohol). Small-sized, medium brown animal with lighter appendages and light brown wing membrane. Maxillary palp formula I-II-V-IV-III. Abdominal tergites and sternites light spotted with rather large and less pigmented alveolar haloes. Forewing length 9 mm. Male genitalia (Fig. 23). In lateral view IX t h segment quadrangular, short and tall, ventral half shorter than dorsal; dorsoapical area with erect setae. Segment X composed of dorsal branch with subapical flaps and straight ventral branch (Figs 23, 25); in dorsal view apical excision pentagonal and subapical flaps laterad directed (Fig. 24); apices of ventral branch without anal sclerites, deeply bifid, its mesal lobe pointed; weakly discernible U-shaped paraproct shifted anterad at the apices of the ventral branch, its tergal band connecting paraproct to phallobase short. Cerci reduced. Ventrum of harpagones shorter than dorsum of coxopodites. Phallic apparatus consisting of very short phallotheca with phallobase (Fig. 26); dorsal processes of phallotheca composed of longer unpaired upper and less sclerotized slightly shorter lower lobes divided medially to its half; phallobase connected to U-shaped paraproct by median tergal band and by tenons (clasper hanger of Ross) and tendons (clasper tendon of Ross) to dorsobasal area of coxopodite; aedeagus (phallicata) with a more sclerotized digitiform dorsal process and less sclerotized, more robust ventral arm with hammer-shaped apex; a pair of membranous, weakly discernible blunt lateral arm or parameres shorter than dorsal processes. Type material - Holotype, male, HNHM. Bulgaria: Sofia province, Rila Mts, Borovec, Prava Marica Stream at Zavracica mountain hut, 2190 m, N42°10.075', E23°38.504', 8.IX. 2005, leg. M. FÖLDVÁRI & D. MURÁNYI. Paratype, female, HNHM. Bulgaria: Sofia province, Rila Mts, Borovec, Prava Marica Stream at Zavracica mountain hut, 2190 m, N42°10.075', E23°38.504\ 8.IX.2005, leg. M. FÖLDVÁRI & D. MURÁNYI. Etymology - This species is named with reference to the peculiar straight ventral branch of the X t h segment; "akutila" is "straight" in Sanscrit. Diagnosis - This new species belongs to the R. tristis species group. It is closest to R. pseudotristis KUMANSKI, 1987, but differs by having (1) abdominal tergites and sternites with very pronounced light coloured alveolar haloes, R. pseudotristis has no light ring around alveoli at all; (2) in dorsal Annls hist.-nat.
