Melanagromyza malayensis Sasakawa 

Melanagromyza malayensis Sasakawa, 1963 a: 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 1963 a: fig. 9 b, c).

Distribution. Malaysia (Peninsula), Thailand (new record).
