Measurements. Total length: 16–17.1; head length: 1.9–2.0; head width: 3.1–3.2; pronotal length: 3.4–3.5; pronotal width: 10–10.3; scutellum length: 7.5–7.8; scutellum width: 5.8–6.0; abdominal width: 8.6–8.8; length of antennal segments. I: 1.0; II: 2.0–2.1; III: 1.2–1.5; IV: 4.7–5.0; V: missing.

Diagnosis. Anterolateral margin of pronotum with solid black stripe along all of its extension. Anterolateral margin punctured dorsally. Cicatrices of pronotum with black punctures delimiting anterior sulci (Fig. 20I). Scutellum with anterior margin concolorous (Fig. 20I). Body ventrally with dark brown stripes (Fig. 20J). Male genitalia (Fig. 17A–D). Pygophore with dorsal rim sinuous, presenting a small median dark, rounded projection (Fig. 17A). Superior process of genital cup oblong, narrow, ventral margin with two subtriangular small projections; process contiguous to dorsal rim; visible in dorsal view (Fig. 17A–C). Paramere with a large subtriangular and truncated lobe directed anteriorly; posterior lobe short and triangular; inner low carina splitting distally finishing at anterior and posterior apices (Fig. 17B–C). Proctiger with laterodorsal tufts of long setae separated by narrow, sparsely setose ridge; posterior face pentagonal, upper part swollen (Fig. 17A–D). Expansions of ventral rim acuminated and developed, far exceeding the level of the posterolateral angles in ventral view (Fig. 17D). Female (Fig. 17E). Valvifers 8 wide, posterior margin sinuous; inner angles rounded and convergent reaching basal part of valvifers 9; inner margins with narrow and elliptic excavation. Valvulae 8 exposed.
