Ulidia transcaspica sp. nov. from Turkmenistan and Uzbekistan is described and depicted. The new species is close to U. nigricubitalis Zaitzev, 1982 from Mongolia; U. nigricubitalis is also depicted. Описан новый вид Ulidia transcaspica sp. nov. из Туркменистана и Узбекистана, близкий к U. nigricubitalis Zaitzev, 1982 из Монголии. Для обоих видов приведены иллюстрации.

INTRODUCTION specimens belonging to the new species described below. The new species is similar The genus Ulidia Meigen, 1826 includes to Ulidia nigricubitalis Zaitzev, 1982, which 19 described species distributed mainly in was described from a single male collected semiarid areas from the Mediterranean in in Mongolia (Zaitzev, 1982).

Sometimes it is difficult to distinguish MATERIAL AND METHODS Timia Wiedemann, 1824 from Ulidia.
