Note on synonymy in Asiatic Ceriagrion species (Zygoptera: Coenagrionidae)

Ceriagrion chaoi Schmidt, 1964 is shown to be a valid species. C. latericium Lieftinck, 1951 is a junior synonym of C. auranticum Fraser, 1922. ASAHINA (1971) clarified the status of the four Ceriagrion species which were treated as "species incertae sedis” in his revision of Asiatic Ceriagrion (ASAHINA, 1967). One of these was C. auranticum FRASER, 1922, described rather inadequately and without illustrations on the basis of 3 males from Bangkok.
