Notes on the distribution of Dalmatinella simonae (Gastropoda: Hydrobiidae) in Croatia and the utility of barcoding in its determination

Abstract

Dalmatinella simonae is a recently described species from Lake Sladinac and the river Cetina (Croatia). New findings from the rivers Cetina, Neretva and Ruda indicate a wider distribution of this species especially in comparison with its relative D. fluviatilis, known only from a short section of the river Zrmanja. Its occurrence is also probable in the river Neretva in Bosnia and Herzegovina. Barcoding analysis, using mitochondrial cytochrome oxidase subunit I (COI), confirmed the occurrence of this species in new sites, and the nearly complete lack of genetic divergence.
