Head shiny, unpunctured, with weakly protruding eyes on the sides. Antennal segments 1 and 2 distinct, 3-5 slightly longer than wide, 6-8 spherical, with segments 6 and 8 distinctly smaller than segment 7, the three-segmented club distinctly offset. Pronotum slightly wider than long (1.2:1), shiny with fine and widespread punctures, which are recognizable as slightly raspy towards the base, greatest width just before the middle, evenly rounded from here to the front, converging straight towards the back. In the ♁, the middle of the pronotum is very weakly elevated before the base. Elytra narrower than long (1:1.3), shiny and compared to the pronotum with significantly coarser (recognizable as raspy at the base of the pronotum) and denser punctures; greatest width before the middle (in the first third), sides more strongly rounded to the front, weaker to the back. The small basal pits, located in the middle between the suture and the lateral margin, with a filling tomentum pad. In the male, the front tibiae are slightly thickened in their apical half, with a noticeable notch towards their tip on the inner side (Fig. 39). Underside: ♁ with metaventrite moderately depressed, shiny, sparsely hairy. Evenly fine and widespread punctured throughout (centre, marginal ridge, sides) (Fig. 38). Genitalia: Length 0.32-0.35 mm.
