Diagnosis: Eye diameter 1.4× longer than interocular distance. Maxillary palpomere 2 is about 2.5× longer than 3. Pronotum 1.2× wider than long, median longitudinal carina at apical 1/4 bifurcating medially forming areola occupying the median 2/4, connected to the posterior margin by a basal carina. Elytra dark brown with a yellow irregular median transversal band (Fig. 3). Phallus curved from basal half in lateral view, with apex slightly ventrally-oriented dorsally-oriented and hooked apical projections (Fig. 9a, b), each paramere with ventral subapical thorns (Fig. 9c).
Description: Basal 1/3 of maxillary palpomere 2 yellow. Trochanters yellow, basal 1/4 of median femur yellow. Pronotum dark brown with lateral sides and anterior margin yellow. Elytra dark brown with a short portion of the humeral region and irregular median transversal band yellow (Fig. 3).
Eye diameter 1.4× longer than interocular distance in male. Male antennomeres 3−5 almost of the same length. Maxillary palpomere 2 almost as long as 4 and about 2.5× longer than 3. Pronotum 1.2–1.3× wider than long, median longitudinal carina bifurcating in anterior 1/4 forming areola occupying the median 1/2, connected to the posterior margin by a basal carina. Scutellum with posterior margin shallowly emarginated. Prosternum trapezoidal, mesoventrite trapezoidal. Elytra 3.9× longer than humeral width in male, 4.4–4.5× longer than humeral width in female, and intercostal intervals with irregular cells. Hind femora 2.9× longer than trochanter length. Male genitalia with short phallus, curved from basal half in lateral view, with dorsally-oriented hooked apical projections and dorsal subapical thorns (Fig. 9a), apex of phallus slightly ventrally-oriented (Fig. 9b); parameres elongate, almost as long as phallus, ventrally bent towards apex in lateral view, almost straight in ventral view, apically rounded with ventral subapical thorns (Fig. 9c) and joined basally by a ring-like bridge, phallobase asymmetrical and ¾ as long as parameres length (Figs. 9–10). Female genitalia with short valvifers forming thin ventral bridge, coxites long, medially arcuately emarginate, styli as long as valvifers (Fig. 18). Body length: 6.0 mm (males), 5.9–6.7 (females), humeral width: 1.3 mm (males), 1.3–1.5 (females).
