Thorax: length: 1.8–2.0 mm (mean = 1.9 mm, n = 7). width: 2.3–2.5 mm (mean = 2.4 mm, n = 7); 0.79 as long as broad; disc margins broadly rounded to constriction, slightly convex in lateral view, punctures small, clothed with narrow, elongate, dirty white scales, some laterally and ventrally; base sinuate; mesosternal intercoxal process not prominent, clothed with narrow, elongate, dirty white scales; scutellum large, longer than broad, subimpressed clothed with ochroleucus scales; mesepimeron densely clothed with clavate, ochroleucus scales; mesepisternum and metepisternum clothed with narrow, elongate, dirty white scales; metasternum with lateral macula of ochroleucus scales proximal to metacoxae. Elytra: length: 3.7–4.0 mm (mean = 3.9 mm, n = 7); striae deep, with large punctures and small, narrow, elongate, dirty white scales; humeri rounded; intervals broad, flat, uniformly clothed with narrow, elongate, dirty white scales; crosshatched setae short, not prominent. Legs: length of hind femur 2.8–3.0 mm (mean = 2.9 mm, n = 7), tooth medium, acute; pro­ and mesofemoral teeth medium, but smaller than hind femoral tooth; femoral clava medium­sized; all femora clothed with narrow, elongate, dirty white scales; tibiae subsinuate, pro­ and mesouncus large longer than tarsal claw, metauncus short, small, acute. Abdomen: sternite 1 and 2 equal in length, sternite 2 ascending to 3; sternite 3 longer than 4, combined longer than 5; sternite 5 truncate apically with median depression; sternite 2 with lateral macula of narrow, elongate, ochroleucus scales, remaining sternites with dirty white scales. Pygidium: large, with elongate dirty white seta­like scales.
