Description - Measurements (in mm, n=l 0): HW = 0.69 (0.67-0.72); TW = 0.65 (0.63-0.66); PW = 0.71 (0.70-0.73); SW = 0.98 (0.94-1.02); AW = 0.95 (0.90-1.02); HL = 0.52 (0.50-0.54); EL = 0.17 (0.15-0.18); TL = 0.22 (0.20-0.24); PL = 0.63 (0.60-0.64); SL = 0.99 (0.96-1.02); SC = 0.92 (0.86-0.98); BL = 4.74 (4.56-5.00); Head+pronotum+elytra = 2.25 (2.20-2.36) mm. - Colour. Head and pronotum uniformly dark brown, eyes appear dark, but slightly silvery. Elytra bicoloured: the central parts of discs are yellowish light brown, the rest (lateral edges, apical margin and a triangular area around the tip of the scutellum) are darker brown. Abdomen dark brown. Mouthparts and legs are light to medium brown, central parts of antennái segments 3-11 usually a little darker. - Shape and sculpture. Vertex has 2 shallow impressions (at the sides of the center of midline). The pronotum bears fully developed but rather slightly elevated anchor-like ridge, with 2 straight depressions starting from the corners of the anchor heading anterio-laterad. The elevated areas don't differ in shininess or punctation, therefore giving the pronotum a rather flat and dull appearance, devoid of characteristic markings. Pronotum has well-formed and simple posterior angles (cca. 95°), sides and posterior edge bear thin and slightly visible rim. - Punctation and microsculpture. Head, pronotum and abdomen finely but distinctly microsculptured. The punctation on the head is distinct and dense, apparent microsculpture in the interspaces (1/2 of puncture diameters). On the pronotum similarly distinct punctures, interspaces 1/1-1/3 puncture diameters (slightly uneven puncture sizes); microsculpture prominent in the interspaces. Elytra has shallow and irregularly sized punctation, interspaces generally about one-fourth of diameters of largest punctures; on the surface between the punctures microsculpture is only slightly apparent. - Pubescence. Forebody with rather uniformly
