    A new member of an entirely Anatolian clade of the Horatiinae DW Taylor, 1966, Hydrobiidae W. Stimpson, 1865
    (Taylor & Francis Ltd, 2025) Odabasi, Deniz Anil; Falniowski, Andrzej; Hofman, Sebastian; Jaszczynska, Aleksandra
    A species new to science, representing the family Horatiinae, is described from Da & gbreve;& imath;lcak Spring in Da & gbreve;& imath;lcak Nature Park in the Seyhan River Basin. This is a minute snail characterised by a broad low-spired shell with broad parietal lip, radula with median cusp of the central tooth twice longer than the adjacent ones, bursa copulatrix large and spherical, one distal receptaculum seminis long and sac-shaped, penis broad and gradually tapering with pointed tip, and vas deferens well visible, running in zigzags. The new species forms the sister lineage of Anadoludamnicola & Scedil;ahin, Koca & Y & imath;ld & imath;r & imath;m, 2012 and an undetermined representative of the genus Sheitanok Sch & uuml;tt & & Scedil;e & scedil;en, 1991 in a mitochondrial phylogeny based on partial sequences of the cytochrome c oxidase subunit I (COI) gene. These three taxa form an entirely Anatolian clade.

    Entirely Anatolian Hydrobiid (Caenogastropoda-Truncatelloidea-Hydrobiidae) Clade Revisited: Two More New Genera and Six New Species
    (Mdpi, 2025) Jaszczynska, Aleksandra; Hofman, Sebastian; Odabasi, Deniz Anil; Ekin, Ihsan; Sirbu, Ioan; Falniowski, Andrzej
    Previous studies identified a clade of the Hydrobiidae endemic to Anatolia, with no closer relationships with the European snails, despite close relations between the fauna of these two regions. Three genera-each monotypic: Sheitanok Sch & uuml;tt et & Scedil;e & scedil;en, 1991, Anadoludamnicola & Scedil;ahin, Koca et Y & imath;ld & imath;r & imath;m, 2012, and Kozanium Odaba & scedil;& imath; et Falniowski, 2025-belonged to this clade. Our study describes the Hydrobiidae collected at five springs in Anatolia. Shell morphology and biometry, radulae, soft parts pigmentation, female reproductive organs, and penes are described and illustrated. Cytochrome oxidase subunit I (COI) sequences have been used to infer phylogenetic relationships and species distinctness of these snails. An integrative taxonomic approach resulted in the distinction of six species new to science. One of them belonged to the genus Sheitanok, another one to Anadoludamnicola. The other four species are clustered into two genera not described thus far, and the offered names are Dicle and Adaniya. It is noteworthy that three species recognized within one of these genera were clearly demarcated both molecularly and morphologically (morphological differences were higher than typical of the hydrobiid congeners). However, two of the three techniques of species delimitation based on the molecular sequences did not confirm their distinctness. This stresses the necessity of a holistic approach in the truncatelloid taxonomy.
