Body length 1.3–1.9 mm . Postvertical bristles slightly divergent, ca . 2/3 as long as inner occipital bristle. Postocellar bristles cruciate, over half as long as postvertical bristle. Head height ca . 2.8–3.1 times genal height. Preapical palpal bristles ca . 2.5 times as long as maximum palpal width. One pair of presutural dorsocentral setulae distinctly longer than acrostichal setulae inside. Posterodorsal katepisternal bristle over 4/5 as long as distance between bristle base and wing base. Wing pigmented, but maculation indistinct. Length of second costal sector ca . 0.46–0.48X length of third. Mid femur of male with 8–10 proximal ventral bristles and a distinct row of anteroventral setulae. Male terminalia: Sternite 5 with two (rarely three) pairs of short, stout bristles. Surstylus with a truncate apex in lateral view. Cercus distinctly longer than surstylus, with distal half narrow in posterior view. Dorsal whip­like sclerite of distiphallus with a small nodule. Ejaculatory apodeme slightly shorter than half length of aedeagal apodeme. Female terminalia: Two sclerites of sternite 8 indistinct. Tergite 10 with two small bristles, without a posteromedial patch of small setulae. Spermathecae with distal portions similar in length to basal portions. Ducts of paired spermathecae ca . 2.5 times as long as spermatheca.
