The former was collected at two relatively distant sites, the Krapina and the Zrmanja rivers, while the later was collected at the Krupa River. Both species were identified by morphological characteristics as well as DNA barcoding method. We calculated the uncorrected pairwise distances within Adicella and used molecular phylogenetic approach to delimit species.A.cremisafrom Croatia showed no significant difference in the mtCOI region and they are highly similar to A. cremisa from Italy. Additionally, the ecological preferences and distribution of Adicella species are presented. Our findings represent a significant contribution to the aquatic biodiversity of the Western Balkans.

All locations were visited three times: in spring, sum- mer and autumn period in 2014. For identification of col- lected specimens standard literature was used (Malicky 2004a). Systematic presentation follows Morse (2017). All physico-chemical parameters were analysed accord- ing to standard analytical methods for assessment of surface water quality (ISO norms), with Krapina River being sam- pled monthly while Zrmanja and Krupa rivers being sam- pled five (January, February, May, September and Novem- ber) and six times (January, February, May, July, Septem- ber and November), respectively, by staff of Hrvatske vode, Central Water Management Laboratory.
