The 24 species have hitherto been recorded from the Oriental region, of which five species, Ophiomyia atralis (Spencer) , O . conspicu a (Spencer), O . rotata (Spencer) , and two bean flies: O . centrosematis (Meijere) and O . phaseoli (Tryon) , have been known to occur in Thailand (Sasakawa 1977, 1981: Spencer 1986). Six further species are recorded below, three of which are new to science. The males of three species, Ophiomyia cornuta Meijere, O . setituberosa Sasakawa, and O . striata sp . nov . , have the vibrissal fasciculus, respectively, which is one of the generic characters. The distinctly raised facial carina as the other generic character is lacking in some species. All the species without these generic characters are clearly confirmed in their generic position by the characters of male genitalia such as surstylus, hypandrium and phallus, and larval posterior spiracles (shape, number of opening bulbs, etc). The larvae of this genus are known as the leafminers, external or internal stem-miners (rarely fruit-miners).
