Rediagnosis of four species of Alburnus from Turkey and description of two new species (Teleostei : Cyprinidae)

Abstract

Alburnus carinatus from Lakes Manyas and Ulubat), A. istanbulensis (small rivers in Turkish Thrace and Lake Sapanca), A. nicaeensis (Lake lznik) and A. derjugini (River Coruh in north-eastern Anatolia) are valid species and are rediagnosed. Alburnus sapancae (from Lake Sapanca) is a simultaneous subjective synonym of A. istanbulensis and this last name has precedence. Two new species are described: Alburnus battalgilae, from River Gediz drainage and A. attalus from River Bakir drainage (Turkey).
