A new West Balkanian sand-goby (Teleostei: Gobiidae)
A new species of West Balkanian freshwater sand-goby Pomatoschistus montenegrensis sp. nov. (Teleostei: Gobiidae) is described from the Morača River, southern Montenegro, and shown to be related to the euryhaline Adriatic Pomatoschistus canestrinii. The generic status of these two species is discussed with reference to the limits of Pomatoschistus (type Gobius minutus) and the status of a subgenus [Ninnigobius (type-species Gobius canestrini)]. The habitat and the local distribution of the new species are described.
