Diagnosis. This species has extremely distinctive genitalia, with few, relatively thick setae on the epandrium and the phallus strongly curved at the base.
Description. Body 1.7–1.9 mm long. Frons brown and relatively wide; frontal width range 0.43–0.48. Frontal ratio 1–1.17. Twelve large frontal setae present, including one pair of supra-antennal setae. Ventral interfrontal setae slightly wider apart than dorsal interfrontal setae. Ocellar triangle 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 light brown, short, broad, with 4 subequal setae. Pleuron yellowish-brown dorsally to whitish ventrally. Foretibia with anterodorsal row of several differentiated 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 0.47 wing length; range 0.46–0.49. Costal sector ratios 4–4.33:1. Halter knob yellowish-brown. 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 squared with slightly rounded margins; length and depth of epandrium subequal. Ventral elongate triangular process present; margin of epandrium concave posterior to ventral triangular process. Setae twice length of setae on cercus present along entire posteroventral margin of epandrium, ending at elongate triangular process; one enlarged seta triple the size of setae on cercus present on posterior margin of the epandrium, ventral to cercus. Phallus elongate, greater than length of epandrium, and strongly curved at base. Remainder of phallus narrow and straight with distinct separation between sclerites near apex.
Distribution. One of the most widespread species; broadly distributed across the range of the genus.
