Description
Summary:Genus Conventus Pirogov & Starobogatov, 1974 stat. nov. Type species: Pisidium conventus Clessin, 1877. Diagnosis: The shell is small (up to 3.3 mm in length), oval, or rounded. The beaks are rounded and slightly prominent, and somewhat offset to the posterior edge of the valves (Figs 5C and 6C). Pores are rare. Only one (exhalant) siphon is present (Fig. 7C). The outer demibranch is completely reduced. Reproductive biology: The members of the genus are characterized as synchronous brooders (embryos are developing within a distinct brood sac). Distribution: The range of the genus covers Europe, Southeastern Asia, and North America, including high-latitude (Arctic) regions (Fig. 3F). Remarks: In our phylogenetic trees, the species Odhneripisidium ellisi, Odhneripisidium insigne Gabb, 1868, O. conventus, and Odhneripisidium sp.1 form a well-maintained clade that was previously designated by Saito et al. (2022) as Neopisidium Odhner, 1921 (Fig. 2; Supporting Information, Fig. S4).
