Abstract
Mimadiestra gen. nov. (type species: M. biloba sp. nov.) is described from Thailand. Megadiestramima Storozhenko et Gorochov, 1992 and Leodiestramima Storozhenko, 2009, stat. nov. are considered as separate genera, therefore, three new combinations are proposed: Leodiestramima exculta (Gorochov, 1998), comb. nov., L. lecta (Gorochov, 1998), comb. nov., L. orlovi (Gorochov, 1994), comb. nov. A key to genera of the tribe Diestramimini is given.
