New data on Niphargus boskovici S. Karaman, 1952 and some other Gammaridean amphipods from the western Balkans (Contribution to the knowledge of the Amphipoda 279)

Abstract

Several species of amphipods of the suborder Gammaridea (Amphipoda) from the western Balkans are treated in this work. The subterranean amphipod Niphargus boskovici S. Karaman, 1952 (fam. Niphargidae) is redescribed and figured from new localities of the Metković region (Croatia), and its relationships with some other members of this genus are discussed. The species Niphargus salonitanus S. Karaman, 1950, known from various subterranean localities in Dalmatia, was discovered on Korčula Island (Adriatic Sea, Croatia) and some of its taxonomical characters are presented. The subterranean species Typhlogammarus mrazeki Schäferna, 1906 (fam. Typhlogammaridae), known from various subterranean waters in Montenegro, Bosnia and Herzegovina and western Croatia, was discovered near Dubrovnik in the cave Špilja za Gromačkom vlakom. The epigean species Gammarus roeselii Gervais, 1835 (fam. Gammaridae), widely distributed over Europe and Asia Minor, was discovered in a spring near Pecka (Croatia) and the distribution of this species in Croatia is discussed. The epigean species Gammarus fossarum Koch, in Panzer, 1836, distributed in Europe and some parts of Asia Minor, was discovered in numerous new localities in Croatia and Bosnia & Herzegovina, and some remarks on this species in Croatia and Bosnia and Herzegovina are presented.
