Unraveling a new lineage of Hydrobiidae genera (Caenogastropoda: Truncatelloidea) from the Ponto-Caspian region

description Phylogenetic analyses of the highly diverse (non-marine aquatic) gastropod family Hydrobiidae Stimpson, 1865 have revealed seven main lineages, most of which represent subfamilies. The subfamily Pseudamnicolinae Radoman, 1977, and specifically the genus <em>Pseudamnicola</em> Paulucci, 1878 (mainly inhabiting western and central Mediterranean regions), contributes substantially to this hydrobiid richness. Most of its congeners have been described in terms of their shell and penis features, which are of limited diagnostic value. Hence, the taxonomic status of some <em>Pseudamnicola</em> species needs to be revised, particularly of those inhabiting marginal regions, such as the Ponto-Caspian domain, largely occupied by the subfamily Pyrgulinae Brusina, 1882. Here we present a molecular phylogeny including species of both subfamilies along with extended morphological descriptions to confirm assignments of the Iranian species <em>Pseudamnicola zagrosensis</em> Glöer &amp; Pešić, 2009; <em>Sarkia kermanshahensis</em> Glöer &amp; Pešić, 2009 (originally within <em>Pseudamnicola</em>) and <em>P. saboori</em> Glöer &amp; Pešić, 2009. Our COI-based tree rejects these assignments suggesting a new potential lineage, sister to the pyrgulinid species, and comprising three genera: <em>Shadinia</em> Akramowski, 1976, <em>Intermaria</em> gen. nov. and <em>Persipyrgula</em> gen. nov. These genera differ molecularly by 3.6%–8.5%, and are diagnosable by penis, female genitalia and radula features. Our findings evidence the high morphological variability of pyrgulinid species and provide insight into the origins and evolution of the freshwater Ponto-Caspian fauna.
