Diagnosis. This species can be recognized by the strongly projecting phallus with an expanded rounded apex.

Description. Body 2.1–2.2 mm long. Frons brown; frontal width range 0.43–0.48. Frontal ratio 1–1.08. Twelve large frontal setae present, including one pair of supra-antennal setae. Ventral interfrontal setae slightly wider apart than dorsal interfrontal 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 with anterodorsal row of several short setae, decreasing in size apically. Midtibia with one posterodorsal seta near base and one slightly more apical anterodorsal seta present; dorsally with setal palisade extending from base to midlength, more apically with transverse rows of fine setulae; few posterodorsal setae slightly enlarged apically. 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. Costal sector ratios 2.43–2.49:1. Halter knob yellowish-brown. Tergites 1–6 brown. Epandrium seed shaped; length greater than depth. Ventral margin with two large triangular processes present; one smaller triangular process at midlength, and one larger triangular anteroventral process. Ventral margin concave between two triangular processes and concave posteriorly to midlength triangular process. Posteroventral margin of epandrium rounded. Setae on posteroventral margin of epandrium same length as setae on cercus on rounded margin, increasing in size from rounded margin to midlength triangular process. Phallus strongly curved near base and projecting posteriorly. Phallus length approximately same as length of epandrium; darkened sclerotization on dorsal and ventral margins of phallus. Apex of margin distinctly rounded.

Distribution. Malaysia, Philippines.
