ZooKeys 729: 103–127. https://doi.org/10.3897/zookeys.729.20615 Abstract Distribution data on many freshwater fish species in Croatia are scarce and species identifications are dif- ficult, requiring further detailed studies. This paper presents a report of the Italian gudgeonRomanogobio benacensis from the Mirna River in the Istra Peninsula in Croatia, in the south-east from its previously known distribution range.
