Diagnosis. This species is easily recognized by the extra frontal setae and the short, ventrally bilobed epandrium.

Description. Body 2.5–3.2 mm long. Frons dark brown and relatively narrow; frontal width range 0.38–0.43. Frontal ratio 1.06–1.16. Frons relatively setose, with 12–18 large frontal setae present, with supranumerary frontal setae present along the ventrolateral margin of the frons (one specimen of this species had no extra frontal setae). Ocellar triangle dark brown and separated from rest of frons, with rounded posterior margin. Lateroventral part of frons with white triangular region with thin black line. Scutum yellowish-brown. Scutellum brown, short, broad, with four subequal setae. Pleuron yellowish-brown dorsally to whitish ventrally. Foretibia without strongly differentiated large setae. Midtibia with one posterodorsal seta near base and row of four anterodorsal setae; dorsally with setal palisade extending from base to midlength, more apically with transverse rows of fine setulae. Hind tibia with several scattered medium-sized anterodorsal setae; dorsally with complete setal palisade, with row of small posterodorsal setulae closely parallel, followed more posteriorly by bare space before regular setulation. Wing large; mean costal length 0.53 wing length; range 0.48–0.57. Costal sector ratios 2.44–3.25:1. Halter knob yellowishbrown. Abdominal tergite 1 yellow except brown laterally, large, and extending laterally on segment. Tergites 2–6 similar in coloration except more brown laterally. Epandrium somewhat rectangular in shape; depth greater than length. Epandrium ventrally bilobed with lobes close together. Posteroventral margin of epandrium concave. Setae on posterior margin of epandrium about same size as setae on cercus; setae decreasing in size ventrally and ending at base of right lobe. Phallus short, about same length as posterior

Distribution. Cambodia, Thailand.
