Genus Agromyza Fallén

This genus is well represented in the Palaearctic region. Only four species, Agromyza latipennis Malloch, A. oryzae (Munakata), A. panici Meijere and A. phragmitidis Hendel, have hitherto been known to occur in Thailand (Sasakawa 1981; Spencer 1961a, 1986). The occurrence of three more species, A. comosa Spencer, A. flavisquama Malloch and A. pennisetivora Spencer, are recorded below for the first time.

Agromyza flavisquama, A. latipennis, A. oryzae, A. panici, A. pennisetivora and A. phragmitidis are known as leafminers of the Poaceae (Gramineae) . The male genitalia of A. comosa, figured in Sasakawa (1972: fig. 1) and Spencer (1962a: fig. 26), are characteristic of these grass-miners.
