Description: Maxillary palpi brown. Pronotum yellow with median brown subtriangular patch. Elytra yellow, with posterior 1/4 dark brown (Fig. 5). Basal portion of trochanter and femur yellow.

Eye diameter 1.6× longer than interocular distance. Antennomeres 4–5 of the same length, 1.2× longer than antennomere 3. Maxillary palpomere 2 about 2.7× longer than 3 and 1.3× longer than 4. Pronotum subpentagonal, lateral margins almost straight, slightly divergent posteriorly, basal margin bisinuous, median longitudinal carina forming areola at basal half.

Aedeagus with phallus widened in basal 2/5–3/5 and apex bent in right angle to right in dorsal aspect, narrowing before distal ellipsoid expansion (Fig. 12A, B). Phallobase elongate, with short lateroapical thorns and triangular suspensorial arms. Junction between base of phallus and phallobase short and almost as wide as phallus width (Fig. 12A, C).
