Kotlabukh Lake, Odessa Region, Ukraine (approximately 45°25'35"N, 28°59'41"E). Distribution. Limans and lower reaches of rivers Don, Dnieper, Dniester, and Southern Bug entering the northern Black Sea Basin and the Azov Sea (Taganrog Bay), as well as in coastal lakes Kotlabukh and Yalpug ( Vinarski and Kantor 2016 ). The record of an undescribed subspecies of T. boltovskoji from the Caspian Sea mentioned by Anistratenko and Stadnichenko (1995) is probably based on a misidentification. Taxonomic notes. Golikov and Starobogatov (1966) and Alexenko and Starobogatov (1987) introduced a plethora of names for morphologically similar species from the northern Black Sea Basin, partly deriving from subfossil horizons. They differ from Laevicaspia lincta slightly in the number of whorls and outline shape, but overall range within its morphological variability. Here, we consider them tentatively all junior synonyms of L. lincta . Since Starobogatov's type material is unknown, support for this approach requires collection of new material from the type localities of these taxa. Molecular data confirmed the conspecifity of L. lincta and L. milachevitchi ( Wilke et al. 2007 ). Conservation status. Least Concern ( Son 2011e ).
