Body length: Ƌ, 3.1–3.2 mm.

Vertex ( Figs. 1 and 6 ) brownish yellow, with pair of milky irregular preapical spots and with longitudinal milky stripes along inner sides of eyes. Eyes ( Figs. 1, 2, 3 ) brown black. Pronotum ( Figs. 1, 6 ) whitish yellow, with median and posterior margin dark.

Pygofer side ( Fig. 7 ) broad, with 1 dorsal macroseta, numerous microtrichia scattered at caudal area. Pygofer dorsal appendage movably articulated, bifurcate at base, dorsal branch longer than ventral branch, extended beyond apex of lobe. Subgenital plate ( Fig. 8 ) with 3 marginal macrosetae at base, 4 macrosetae on lateral surface, and 2 robust teethlike setae at apex. Style ( Fig. 9 ) with apex inverted-footlike, preapical lobe small, with apex hooklike. Connective ( Fig. 12 ) Y-shaped, with stem truncate apically, central lobe much short than lateral arms. Aedeagus ( Figs. 10 and 11 ) with paired short apical processes, preatrium little longer than aedeagal shaf, dorsal apodeme small in lateral view, gonopore apical on ventral surface.
