Abstract: 
The systematics of Anatolian species of the aquatic snail family Hydrobiidae Stimpson, 1865 has received little attention. Several of these species were previously classified within the circum-Mediterranean genera Pseudamnicola Paulucci, 1878 and Graecoanatolica Radoman, 1973 according to their shell and penis features. Two examples are P. geldiayana Schiltt & Bilgin, 1970 and G. nageli Gl delta er & Pesi6, 2015. However, characteristics of the female genitalia from the original descriptions of these 2 species do not correspond to those of their respective genera. Consequently, their taxonomic status is here re-assessed using DNA sequence data from paratypes and conspecific snails from other popula-tions. Molecular phylogenies based on 3 gene fragments (COI, 16S rRNA, and 18S rRNA) depict these 2 taxa within other hydrobiid subfamilies (i.e., the Belgrandiinae and Hydrobiinae), distantly positioned from their nominal genera. For these 2 species, we also describe unstudied morphological characters, such as those of the radula and ctenidium, and find substantial differences from their phylogenetically closely related taxa. These results support the erection of 2 distinct new genera, Cariohydrobia gen. nov. and Erosiconcha gen. nov., and highlight the importance of combining morphological and molecular evidence to define the taxonomic status of extant hydrobiid species of Anatolia.
