Material examined. 1♂ , 2♀, Phetchabun, Khao Kho National Park, 16˚52.573´N, 101˚08.077´E, 520 m a.s.l., 26 x–2 xi 2006 , Malaise trap, Somchai Chatchumnan. This small, black species was described by a single female, with a slight metallic sheen on the faintly graydusted mesoscutum, collected at Doi Suthep, in December 1957 . Description . The male is described here for the first time, differing from the female in the following points: mesoscutum and abdomen brilliantly shining; frons slightly wider than eye; lunule semicircular; gena 1/8 as high as eye; acr arranged in eight rows; wing length 2.1 mm ; S6 almost five times as long as S5, about 4/5 as long as wide, with shallow emargination posteriorly. Genitalia: epandrium with surstylus roundly projected on its anteroventral part, incurved, bearing 26 spines in three irregular rows, and few pale spines and setae on posterior corner of projection; cercus 1/2 as high as epandrium, with row of five or six stout setae anteroventrally; hypandrium 340 µm long, with basal apodeme about 1/3 as long as sidearm; pregonite with five to seven sensillae; phallapodeme 530 µm long; phallus 400 m long, basiphallus tubular, broadened distally; distiphallus with spinulose lobes near dorsolateral base; ejaculatory apodeme 190 µm long, blade almost symmetrically broadened distally, 110 µm wide. Remarks . The coloration and structures of the male genitalia of this species show similarity to those of the Australian Melanagromyza trifilis Spencer , but this species has only two postsutural dc. The dense spines on the surstylus and spinules on the distiphallus in this species are distinctive (phallus of trifilis : Spencer 1977 b: figs 64, 65). Distribution . Thailand .
