New distribution data for Alburnus sava Bogutskaya, Zupančič, Jelić, Diripasko & Naseka, 2017 and Telestes souffia (Risso, 1827) in the Western Balkans

The distribution data of Alburnus sava and Telestes souffia has been updated in Croatia in comparison to the previously known data. Alburnus sava is much more widespread in the Sava drainage and also occurs in the River Sava near the town of Županja, rivers Drina and Bosna. Telestes souffia has a much more restricted range in Croatia than previously believed and is only known from the Bregana, small, right tributary of the River Sava on the Croatian-Slovenian border. Both species are poorly known and threatened.
