Description (male).
3.5–4.0 mm. Reddish-brown, setae yellowish-brown. Tegument feebly shiny.
Head
. Completely covered by fine, dense punctation; punctures separated by their diameter. Frons flat, clypeus feebly depressed at middle. Clypeus with lateral margins subconvex.
Pronotum
. Base strongly bilobate, concave at middle, straight and obliquely divergent on each side. Posterior angles obtuse. Lateral margin straight, anteriorly feebly convergent to strongly convergent. Anterior angles not sharp.
Elytra
. Interstriae flat, smooth, with distinct microreticulation; punctation extremely fine, evenly dispersed; interstriae bearing 1–2 rows of setae. Anterior inner margin oblique, projecting obliquely from base of 5th striae to fit basal margin of pronotum. Sides of elytra evenly curved.
8th tergite
. Smooth, with fine, superficial punctation. Inner margins completely bordered with superficial furrow, apex with feebly enlarged margin.
Sternites
. Last sternite strongly enlarged; tegument microreticulate, covered with superficial punctation similar to that on 8th tergite. Other sternites normally developed, strongly microreticulate, dull, with punctation restricted to sides.
Legs.
Outer margin of protibia tridentate in apical third, basal tooth small but visible, teeth equidistant. Inner margin notched before apex, with narrow lamella (
Fig. 25
).
Aedeagus
(
Fig. 17
). Left paramere projected laterally in apical third, more strongly projected on inner margin side. Right paramere short, straight, even in dorsal view; evenly curved, rounded at apex in lateral view.
Notes.
Female similar to male, with simple inner margin of protibia.
