Rhyacophila; new species

Sažetak
Forewing length 12 - 14 mm. Size and wing pattern as in R. vulgaris PICTET 1834 to which the new species is closely related. The male genitalia (see figure) correspond with these of Rhyacophila vulgaris with the exception of the ventral part of the aedeagus which is broadened in lateral view, and has a rounded distal part, separated by a constriction, in ventral view. The genital segments of the female are as in R. vulgaris, but in ventral view the membranous part of the segment has three sclerotized patches. This may however also occur in rare cases in R. vulgaris where usually only one such patch is found. The female of R. cabrankensis may be confused with R. simulatrix McL. 1879 where three sclerotized patches occur too, but these are arranged in a different manner: in simulatrix the unpair basal patch is close to the anterior edge of the ventral excision, but in cabrankensis, as in vulgaris, it is situated some distance from it. R. simulatrix and R. cabrankensis may be found together in the same sites. Holotype <$ and several paratypes S and $: Croatia, Izvor Cabranke, 45°36'N, 14°38'E, 500m, 9.9.2004, leg. KuCinic. Several other paratypes S and $ from Croatia, Izvor Kupe, 31.7.2001, leg. KuCinic. Holotype in coll. Department of Zoology, Faculty of Science, University of Zagreb, paratypes in the same collection and in the collection of H. Malicky. Discussion: This species is closely related to R. vulgaris, but is geographically somewhat isolated ; the southernmost populations of R. vulgaris in the region are found in northern Slovenia. The status of cabrankensis as a subspecies of vulgaris or as a good species is debatable, but as it is comparable in the separation from vulgaris like R. foliacea MORETTl 1981 and R. hartigi Malicky 1971 in Italy, we give it the rank of a separate species. - Named after the type locality.
