A description of two new species of the genus Gobio from Central Anatolia (Turkey) (Teleostei: Cyprinidae)

Abstract

The gudgeons of the genus Gobio from Anatolia are reviewed based upon the historical collection of the Hamburg Zoological Institute and Museum, Hamburg University, and recently collected materials. Fishes previously referred to subspecies of Gobio gobio be¬long to at least 8 species. Among them, two new species are described: G. battalgilae from northern Beyşehir Lake system (a Central Anatolian endorheic basin) and G. maeandricus from the headwaters of Great Menderes River (Aegean Sea basin). These spe¬cies are distinguished by a combination of the number of lateral line scales, predorsal and circumpeduncular scale counts, scale pattern on belly, vertebral counts, length of barbel shape of lower lip, and details of colour pattern.
