Abstract
Two new species of the genus Timia Wiedemann, 1824 are described and illustrated. Timia lazebnayae sp. n. from Uzbekistan has yellow body and is similar to Timia gobica Zaitzev, 1982, differing from it only by the entirely yellow flagellomere 1. Timia shatalkini sp. n. from Mongolia has dark body and differs from all other dark-colored representatives of the genus by the cell r4+5 being completely closed, forming petiole at the wing apex. Timia mongolica Zaitsev, 1982 is redescribed and an updated key for yellow-coloured Timia is provided.
