Melanagromyza malayensis Sasakawa, 1963a:35 .
Material examined. 3♂, 1♀, Loei, Phu Ruea National park, 17˚29.907´N, 101˚20. 483´E, 1196 m a.s.l., 5–12 viii 2006, 17˚30.128´N, 101˚20.339´E, 1233 m, 19–26 viii 2006 & 17˚30.740´N, 101˚20.650´E, 1353 m, 26 ix–2 x 2006, Malaise trap, Nukoonchai Jaroenchai.
Measurements: male genitalia—hypandrium 270–370 µm long, with basal apodeme 80–150 µm, slightly broadened vertically at base; phallapodeme 480–630 µm long, phallus 360–440 µm long (distiphallus 220-250 µm long); ejaculatory apodeme 240–260 µm long, 130–150 µm wide.
Remarks. The male genitalia of this species are extremely similar to that of M. dolichostigma, especially in the shape of the surstylus and distiphallus, but this species belongs to the different species-group characterized by a dark fringe on the calypter, not pale as in the dolichostigama -group. Also, in M. malayensis, the surstylus is provided with a row of seven to nine long spines at the base of the anteroventral projection, which is only setose, one stout spine is on the posteroventral corner of the epandrium, and a distiphallus is composed of a long process dorsad of a distal tube (Sasakawa 1963a: fig. 9b, c).
Distribution. Malaysia (Peninsula), Thailand (new record).
