Head brown, with terminal maxillary palpomere dark brown. Pronotum and scutellum yellow. Elytron black, with two large curved yellowish stripes, one c-shaped, situated around outer margin of humeral callus, connected to lateral margin of elytron, another one v-shaped, situated between 2/5 and 4/5 elytral length to apex, connected to elytral suture; apex of elytron yellow. Underside uniformly dark brown, except elytral epipleura and legs yellow. Head moderately large (Fig. 35), 0.35× elytral width (HW/EW=2.86); frontal surface of head capsule slightly convex and rather weakly anteriorly inclined below; punctures on frons fine, separated by 0.5–1.5× a diameter, with sparse long setae in punctures; eyes relatively large, distinctly broader than interocular distance; widest interocular distance 3.2× narrowest width. Pronotum 0.66× elytral width (PW/EW=1: 1.51), pronotal punctures fine, smaller than those on head, separated by 1.0–3.0× a diameter. Scutellum moderately large, triangular. Punctures on elytra moderately large, irregular, obviously larger than those on pronotum, separated by 1.0–2.0× a diameter. Pro- and mesoventrite mat and shagreened, punctures inconspicuous, with sparse short setae. Metaventrite broad and glabrous, median part concaved, with complete median discrimen; punctures sparse and fine, separated by 2.0–3.0× a diameter, with short sparse setae. Abdominal postcoxal line complete, v-shaped, nearly reaching to posterior margin of ventrite 1 (Fig. 64). Male genitalia: Penis short and stout, slightly curved, without penis capsule (Fig. 65); penis guide in lateral view widest at base, gradually narrowed to apex, apex pointed and curved (Fig. 66); parameres slender, sparsely setose at apical half, longer than penis guide, apex curved (Fig. 66); penis guide in ventral view almost parallel at basal 6/7, then gradually narrowing to apex, apex truncated (Fig. 67).
