TAXONOMIC REVISION OF LIVENTAL’S SPECIES OF BRACKISH WATER OSTRACODA (Crustacea) AND DESIGNATION OF NEOTYPES

The aim of this paper is to re-describe LIVENTAL’s (1929) species through the SEM pictures of the specimens included in various historical collections deposited at the Micropaleontological Laboratory of the VNIGRI, St. Petersburg, Russia, since the original Livental’s collection seems to be lost as well as the Azerbaijan collections by Agalarova (AGALAROVA, 1956, 1967; AGALAROVA et al., 1940, 1961). In particular, the revision is based on the VNIGRI collection AZNII27 of L.N. Klein who studied the ostracods of the Azerbaijan area of Babazanan (KLEIN, 1960, the same area studied by LIVENTAL, 1929) and on several other collections from Turkmenistan, the Caucasus and Euxinic/Black Sea? Basin included both in historical collections (Mandelstam, Luebimova, Rozjeva, Stepanaitys) as well as on new findings from the Euxinic Basin. The discussion on each species is accompanied by its synonymy, and an updated geographical and stratigraphical distribution based on the new chronostratigraphical data of KRIJGSMAN et al. (2010) and VAN BAAK et al. (2013). In those few cases where the Livental’s species are still living in the Caspian or Black Sea, the soft parts are described and the ecological parameters given
