Morphology of Dalmatinella fluviatilis Radoman, 1973, a putative endemite of the Zrmanja River (Croatia), was checked. Shell, radula, and soft part anatomy were considered. In both male and female genitalia D. fluviatilis resembled Anagastina and Radomaniola. Molecular phylogeny, inferred from the mitochondrial cytochrome oxidase subunit I (COI) and nuclear 18S rRNA gene partial sequences, confirmed morphological observations: the sister taxa of Dalmatinella being Graecoarganiella, Radomaniola and Anagastina, and Dalmatinella belonging to the Sadlerianinae.
