Some new data on the family Niphargidae from Serbia (Contribution to the Knowledge of the Amphipoda 319)

Summary. Two members of the subterranean family Niphargidae (Amphipoda, Senticaudata) from Serbia (Kosovo & Metohia region) are treated: Niphargus deelemanae latellai ssp. new from Mermerna pećina – a cave near Lipljan, and Niphargus multipennatus Sket 1956 from subterranean waters near Gračanica Lake close to Priština. Both taxa are described and figured, and their taxonomic relationships to some other similar Niphargus taxa are discussed. The subterranean species Karamaniella parapupetta (G. Kar. 1984), known from Croatia and Romania, was discovered in Serbia (village Reka near Brza Palanka). Species N. multipennatus and K. parapupetta are new for the fauna of Serbia
