Four new species of Leuctra Stephens, 1836 from the Balkans (Plecoptera, Leuctridae)

Abstract

Four, presumably microendemic new Leuctra species are described on the basis of morphology of the adult males and females. Each species was collected only in a single mountain range of the western Balkans: Leuctra enigma Kovács & Murányi, sp. nov. (Albania, Çermenikë), L. golijasp. nov. (Serbia, Golija), L. puskasisp. nov. (Bosnia & Herzegovina, Kozara), L. visitorsp. nov. (Montenegro, Visitor). Their morphological affinities and ecology are discussed, phylogenetic relations will be described in the framework of ongoing molecular studies of Balkan Leuctra species. The occurrences of the new species are depicted on a map. A list of Balkan endemic Leuctra species is given. Leuctra dalmoni Vinçon & Murányi, 2007 is new for Albania and Montenegro, Nemoura uncinata Despax, 1934, N. marginata Pictet, 1836 and Isoperla buresi Raušer, 1962 are new for Albania, Nemoura sciurus Aubert, 1949 is new for Bosnia & Herzegovina, while Capnia s. l. vidua rilensis Raušer, 1962 and L. metsovonica Aubert, 1956 are new for Montenegro.
