Description.
Male. Length 7.8-8.2 mm, width 4.9-5.2 mm.
Body dark blue, antennae brown.
Vertex finely and sparsely covered with punctures; frontal tubercles distinctly raised, each separated from each other by a deep furrow; antennae short, robust, extended to the middle of the elytra; antennomeres 1-3 thin, shiny; antennomeres 4-11 wide and flat, with short hairs, antennomere 4 approximately 1.5 × as long as wide; antennomeres 5-6, each approximately 1.2 × as long as wide; the length of each of antennomeres 7-9 equals its width; antennomere 10 approximately 1.2 × as wide as long; antennomere 11 approximately 1.2 × as long as wide; antennomeres 2 and 3 shortest, antennomere 3 similar in length and shape to antennomere 2, antennomere 4 longest, 1.2 × as long as antennomeres 2 and 3 combined; antennomeres 5-10 gradually shortened, shorter than 4; antennomere 11 slightly longer than 10, pointed.
Pronotum approximately twice as wide as long, with rounded lateral margins; disc sparsely covered with punctures, with a lateral pair of shallow impressions.
Scutellum triangular, with rounded apex, smooth, impunctate.
Bases of both elytra wider than the pronotum, gradually widen posteriorly and rounded at apex; dorsal surface slightly convex, irregularly covered with punctures, the interstices between punctures equal to diameter of individual punctures.
Metasternum twice as long as mesosternum; prothoracic legs shortest, mesothoracic legs slightly longer, metathoracic legs longest.
Ventral surface of abdomen with 5 segments, segment 1 longest, segments 2-4 gradually shortened, apical segment slightly longer than segment 3, three lobes.
Aedeagus slender, parallel-sided, basally widened, apex rounded. In lateral view strongly bent.
Female. Length 8.0-8.2 mm, width 5.0-5.4 mm.
Antennae antennomeres 1-3 thin, shiny; antennomeres 4-11 with short hairs, antennomeres 7-11 wide and flat, each approximately 1.2 × as wide as long; apical sternite flatted.
Differential diagnosis.
This species can be distinguished from other species by wide and flat antennae and the shallow impressions of the pronotum.
Distribution.
