Male
Body oblong, shining, densely covered with short black setae. Coloration of body black with dully bluish luster on elytra; labrum, maxillary palpomere I, and tarsi brown; antennomeres I–III yellowish-orange.
Head narrower than pronotum, very densely punctate; vertex slightly convex dorsally; eyes relatively large, prominent; HL/HW 0.76–0.90 (0.81). Antennae (Fig. 7B) long; antennomere III (Fig. 8B) transversal trapezoidal, distinctly projecting laterally, shallowly concave in dorso-mesal portion, L/W = 0.70; approximate ratio of each antennomeres (n = 1) as 8.3: 1.0: 5.0: 2.0: 2.2: 2.0: 2.0: 2.0: 2.0: 2.0: 3.5. Pronotum quadrate, widest near anterior margin, rounded and obscure in antero- and postero-lateral angles, punctate as in head; PW/PL 1.18–1.33 (1.24). Scutellum semicircular, covered with fine punctures. Elytra oblong, widest at apical 1/4; sides gradually expanded postero-laterally; EL/ EW 1.36–1.55 (1.45); EL/PL 2.52–2.88 (2.67); EW/PW 1.38–1.55 (1.48); TL/EW 2.30–2.56 (2.44). Legs relatively long and slender; fore tibia (Fig. 12A) enlarged, deeply excavate. Caudal margin of tergite VII shallowly concave.
Aedeagus (Fig. 9B) about 1.13 mm, concave at aedeagal apex (Fig. 12C). Gonoporal piece (Fig. 3B) straight, slender, 0.74 mm in GL; GL/AL 2.39. Ligula (Fig. 3B) relatively long, slightly curved; LL 0.27 mm; LW 0.11 mm; LL/LW 2.58; GL/LL 2.71.

Similar to male in general appearance. HL/HW 0.75–0.80 (0.79); PW/PL 1.18–1.30 (1.23); EL/ EW 1.36–1.48 (1.41); EL/PL 2.44–2.73 (2.60); EW/PW 1.45–1.58 (1.51); TL/EW 2.30–2.43 (2.36). Antennae (Fig. 7B) long; antennomere III (Fig. 12B) distinctly expanded laterally, shallowly concave in dorsal portion, L/W = 2.42; approximate ratio of each antennomeres (n = 1) as 8.0: 1.0: 4.4: 2.2: 2.4: 2.2: 2.2: 2.0: 2.0: 2.0: 3.6
