Description
TL: 1.25 mm, TW: 0.83 mm, TH: 0.42 mm, TL / TW: 1.50; PL / PW: 0.60; EL / EW: 1.16.
Body uniformly reddish brown, minute, elongate oval, distinctly convex; dorsum pubescent ( Figure 2E View Figure 2 ). Head small, 0.50 times elytral width (HW/EW = 1: 2.0); frons convex, with fine punctures, separated by 2.0–4.0 times their diameter, with short and sparse hairs, eyes small and coarsely faceted, widest interocular distance 0.69 times width of head. Pronotum 0.78 times elytral width (PW/EW = 1: 1.28), pronotal punctures fine, slightly smaller than those on head, separated by 1.0–3.0 times their diameter. Punctures on elytra large, separated by 0.3–1.5 times their diameter. Surface of proventrite and mesoventrite slightly shagreened, with several setae. Punctures on metaventrite moderately large, separated by 0.8–3.0 times their diameter, with short and dense setae in punctures. Abdominal postcoxal line incomplete, reaching lateral margin and bulging out in middle, divided into two lines, with associated large pits and pores ( Figure 5A View Figure 5 ).
Male genitalia. Penis simple and slender, curved and narrowing toward apex; penis capsule with a short and stout outer process and a small inner one ( Figure 5B,C View Figure 5 ); penis guide in lateral view flattened and nearly quadrate, six times as long as wide, inner margin bulging out at apical third ( Figure 5D View Figure 5 ); parameres short and indistinct,
with five or six long setae; penis guide in ventral view slender, narrowing apical, apex pointed ( Figure 5E View Figure 5 ).
