Abstract
A new species, Clystopyga longifemoralis Varga & Reshchikov sp. n., is described and illustrated from Thailand. Clistopyga latifrontalis (Uchida, 1941) is re-described and illustrated. Clistopyga nagatomii Kusigemati, 1984 is considered to be a junior synonym of C. sziladyi Kiss, 1959 (syn. nov) and also recorded from India for the first time.
