Diagnosis

2.8–2.9 mm long (mean = 2.86 mm; n = 5); 2.24–2.33 times as long as wide. This species is distinguished by the pronotum subquadrate (near type 3) in dorsal view, but only 0.89‒0.97 times longer than wide, and more strongly truncate anteriorly; elytra with a weak basal carina, sides parallel in basal two-thirds, then gradually incurved to broadly rounded apex; declivity beginning after basal quarter, convex, weakly flattened across interstriae 1‒2 in apical quarter, declivital strial punctures shallow, very coarse, striae 2 very weakly impressed, interstriae granulate, interstriae 2 with 2 or 3 larger denticles in apical quarter, posterolateral margin of declivity carinate, never granulate; and protibia with 9‒11 socketed denticles.
