Ecrobia grimmi (Clessin in Dybowski, 1887)

*1887 Hydrobia grimmi Clessin in Dybowski: 55-56.

1888 [ Hydrobia ] grimmi Clessin. - Dybowski: 79, pl. 3, fig. 2.

2009 Caspiohydrobia grimmi (Clessin & Dybowski, 1888). - Filippov and Riedel: 70-72, 74-76, fig. 4 a–d.

Status. Accepted native Pontocaspian species.

Type locality. Caspian Sea (no details).

Distribution. Caspian Sea; Aral Sea; salt lakes near Chelyabinsk, Russia ( Shishkoedova 2010); Lake Sawa, Iraq ( Haase et al. 2010); Arabian (Persian) Gulf ( Glöer and Pešić 2012); possibly also northern and central Kazakhstan and Tajikistan ( Vinarski and Kantor 2016), however, no molecular data are known to confirm the identity of the Central Asian snails. This species was mentioned from depths between 200 and 500 m in the South Caspian Basin of Azerbaijan ( Mirzoev and Alekperov 2017, who reported the species as Caspiohydrobia curta and C. gemma ).

Taxonomic notes. Most of the species that have been assigned to the genus Caspiohydrobia Starobogatov, 1970, including its type species, Pyrgohydrobia eichwaldiana Golikov & Starobogatov, 1966, range within the morphological variability of E. grimmi . Previous examination of some Caspiohydrobia juvenile shells ( Filippov and Riedel 2009, Anistratenko 2013, fig. 4 A–C) as well as reproductive systems and radula did not find any criteria to support differentiation. Probably, all of the thirty Caspiohydrobia species listed by Kantor and Sysoev (2006) and Vinarski and Kantor (2016) for the Caspian Sea are morphotypes of a single species. Prelimary genetic analyses of Caspiohydrobia spp. from salt lakes near Chelyabinsk, Russia (TW, unpublished data) support this assumption.

Conservation status. Data Deficient ( Vinarski 2011b).
