Taxon Name: Hydrobia pontieuxini Radoman, 1973
Taxonomic Notes:
This species is now considered to be a synonym of Ventrosia maritima (Milaschewitsch, 1916) based on
recent molecular work by Kevrekidis et al. (2005) who reviewed the taxonomic status based on
mitochondrial DNA sequences from specimens recorded from Evros delta, Greece. In the past this
species was considered to be part of V. ventrosa by many authors (Van Damme pers. comm. 2009),
however, V.ventrosa is now considered to be a separate taxa to V.maritima based on the data from
Kevrekidis et al. (2005).
Assessment Information
Red List Category & Criteria:
Data Deficient ver 3.1
Year Published:
2013
Date Assessed:
October 30, 2009
Justification:
This species is considered to be part of V.ventrosa by many authors (Van Damme pers. comm. 2009) but
other more recent publications have placed it in Ventrosia maritima. V.maritima and V.ventrosa are both
widespread species in their ranges.This species is assessed as Data Deficient (DD) due to taxonomic
issues. However once the taxonomic issues are solved, it will probably qualify for Least Concern (LC) as a
synonym of Ventrosia maritima.
This species has also been assessed at the regional level:
EU27: Not Evaluated (NE), as this species does not occur in the 27 member states of the European Union
Europe: Data Deficient (Taxonomic Issues, probably LC as synonym of Ventrosia maritima )
Mediterranean: Data Deficient (Taxonomic Issues, probably LC as synonym of Ventrosia maritima )
Geographic Range
Range Description:
This species is now considered conspecific with V. maritima, which is recorded from Evros delta, Greece,
Romania, Ukraine and on the Black Sea coast of Russia.
Country Occurrence:
Native: Bulgaria; Romania; Ukraine
