Description

 Length: 1.56–1.93 mm, width: 1.34–1.62 mm; body rufescent, elongate oval, with rather conspicuous ground punctation and sparse patches of granulate microsculpture; frons broad, depressed at middle, sides of frontal stria rounded, slightly sinuate above antennal bases, complete, weakly arcuate dorsad across front; apical margin of epistoma weakly emarginate; labrum about 2.5× as wide as long, weakly emarginate apically; left mandible bluntly produced along inner edge, right mandible with more discrete, acute tooth; pronotum lacking prescutellar impression or lateral punctures; marginal pronotal stria continuous along lateral and anterior edges; lateral submarginal pronotal stria complete, close to margin, subcarinate, continuous with anterior submarginal stria, pronotal disk depressed along their inner edges; median pronotal gland openings distinctly annulate, located about two-thirds pronotal distance behind anterior margin; elytron with two complete epipleural striae, outer subhumeral stria weakly carinate, forming weak lateral elytral margin continuous with lateral pronotal margin, inner subhumeral stria absent, dorsal striae 1-5 complete, faintly carinate along their outer edges, sutural stria obsolete in basal fourth, all striae converging toward midline apically; elytral disk with numerous coarse punctures near apical margin; prosternal keel truncate at base, carinal striae complete, divergent basally, free basally and apically; prosternal lobe very short, marginal stria weak; mesoventrite truncate along anterior margin, with marginal stria very close to margin; mesometaventral stria broadly arched forward to anterior mesoventral margin, continued by lateral metaventral stria which extends laterally, close and parallel to postmesocoxal stria, strongly abbreviated at midpoint; metaventrite moderately convex; 1st abdominal ventrite depressed, especially at sides along complete inner lateral stria; propygidium uniformly and densely covered with coarse punctures; pygidium with fewer and sparser punctures, mainly at sides, impunctate toward apex; marginal pygidial sulcus well impressed along most of margin, obsolete toward base. Male genitalia extremely similar to those of Operclipygus marginellus (see Fig. 81), differing as follows: T8 (Fig. 81I) slightly more elongate, evenly narrowed to apex; S8 (Fig. 81F) shorter, sides convergent to apex, with narrow apical guides developed only near apex; S9 (Fig. 81E) with base more broadly expanded; aedeagus indistinguishable.
