[ Euphorbiaceae ], 26.vii.1967 , identified by Ananthakrishnan ( SMF ) . Comments. The original description states that this species was collected at Saigon from leaf galls on Aporosa on 19.x.1920, whereas the specimens studied here were labelled by Karny from a slightly different locality, collected 10.xi.1920 from leaf galls on Aporosa leptostachya . From a plant in the same family, Ananthakrishnan described M. moundi (Figs 6 , 11 ) from 17 females and 3 males taken in Hong Kong, and a paratype female is listed below as studied here. This specimen cannot be distinguished as a separate species from the M. vitripennis specimens. The head of M. vitripennis is rather short, the tube is short and approx. as long as the head width, tergite IX setae S1 are longer than the tube and the fore wings are pale. The new synonymy of M. elaeocarpi is based on the paratype female listed below, also one female from India identified by Ananthakrishnan.
