Checklist of the freshwater snails (Mollusca: Gastropoda) of Mongolia Author Marinskiy, Vadim V. text Zootaxa 2017 2017-01-01 4317 1 45 78 journal article 32235 10.11646/zootaxa.4317.1.2 d9650b33-97b2-4d9c-867b-79cd628daf8f 1175-5326 880022 Cd399D08-1Db1-4319-Aa0D-Db560C7C38Df Orientogalba hookeri (Reeve, 1850) ( fig. 5 J ) Regional distribution. O. hookeri iS Very common in Mongolia being a typical dweller of floodplain marSheS, Shallow ephemeral poolS and Similar non-permanent waterbodieS. It occurS throughout the country, except for itS Southern part. Extra-limital distribution. Central ASia, including Southern regionS of Siberia and the Amur RiVer baSin ( VinarSki & Kantor 2016 ). The type locality of O. hookeri iS “Sikkim Himalaya” ( Hubendick 1951 ). Remarks. There are three riVal ideaS on the taxonomic identity of thiS SpecieS. Some authorS (Glöer & Bößneck 2013; Glöer et al . 2014 ) See it aS a Central ASian mountain SpecieS of Radix occurring, among otherS, in Nepal and KyrgyzStan , whereaS Subba Rao (1989) placed it into the genuS Galba Schrank, 1803 . KrugloV & StarobogatoV (1993b) claSSified it aS a member of the (Sub-)genuS Orientogalba KrugloV et StarobogatoV, 1985, that iS allied to but not identical with Radix . Yen (1942) could not find the type SpecimenS of Lymnaea hookeri in the BritiSh MuSeum, whereaS Hubendick (1951, pl. IV, fig. 18) publiShed a photo of the ‘type’ Shell (? holotype ) of thiS SpecieS. Here, we proViSionally follow KrugloV & StarobogatoV (1993b) conception of thiS SpecieS. Limnaeus pervius MartenS, 1867, recorded from Mongolia and adjacent regionS of Central ASia (MartenS 1882; Liu Yueyin 1979), iS probably, a junior Synonym of O. hookeri SenSu KrugloV & StarobogatoV ( VinarSki 2016a ).
