Agromyza flavisquama Malloch 

( Figs 1, 2View FIGURES 1 – 8)

Agromyza flavisquama Malloch, 1914: 318  .

Material examined. 1 ♂ 2 ♀, Loei, Phu Kradueng National Park, 16 ˚ 56.569 ´N, 101 ˚ 49.045 ´E, 274 m a.s.l., 18–25 ix 2006, Malaise trap, Sutin Glong-Iasae.

Remarks. This black species is similar to the Australian Agromyza mellita Spencer, 1977  , in having the yellowish white fringe on the calypter, the brown-tinged tibiae and brown tarsi, and the typical form of the paraphallus as a grass-miner; wing length 1.9 mm in male. However, in A. flavisquama  , the epistome is undeveloped and the distiphallus is short and globular, whereas in mellita  , the epistome is distinctly broad and the distiphallus consists of long tubules distally. The dc are variable in number from 1 + 4 to 0+ 3, and also ori are two to four. Larva mines the leaf of Panicum repens Lamk.  ( Poaceae  ) in Taiwan (Sasakawa 1972).

The male genitalia are described for the first time: surstylus small, lobate, bearing nine or ten spines in two to three irregular rows and few setae along ventral margin; cercus slightly lower than epandrial height, slightly broadened ventrally, densely setose ventroapically; hypandrium 340 µm long, with sidearm curved and basal apodeme very short, pregonite minutely spinulose, postgonite with three or four sensillae apically; phallapodeme 650 µm long; phallus 300 µm long (figs 1, 2, showing typical form of grass-miner, but host plant unknown); ejaculatory apodeme 180 µm long, blade well-expanded, 150 µm wide. The distiphallus is similar structurally to that of A. latipennis  , but its distal lobe is distinctly rounded in lateral side, and the basiphallus is lacked the spinulose, membranous processes.

Distribution. Taiwan, Thailand (new record).
