Abstract
Chersodromia isabellae sp. nov. is described from a sandy beach on the Taman' Peninsula (Krasnodar Territory, Russia). It is closely related to C. nigrosetosa Chvála, 1970 but differs from the latter in having a dorsoapical stylus on a rounded postpedicel and the fore tarsus with tarsomeres 2–5 widened and black. It also resembles C. bureschi Beschovski, 1973 in which only tarsomeres 4 and 5 on the foreleg are black and the male genitalia are slightly different. A key is given for the eight species known from Black Sea and Sea of Azov.References
