Length: 2.18–2.34 mm, width: 2.00–2.12 mm; body rufo-piceous, strongly rounded, widest behind humeri, sides evenly rounded to front and rear, most surfaces coarsely and conspicuously punctate; frons with sides rounded, shallowly depressed at middle, frontal striae diverging anterad, central portion of frontal stria more or less straight, faintly sinuate at middle, crenulate; supraorbital stria absent; labrum about twice as wide as long, weakly emarginate anteriorly; left mandible untoothed, right with small basal tooth; pronotum with weak, indistinct prescutellar depression, ground punctation very conspicuous, interspersed coarser punctures becoming more numerous to sides; marginal pronotal stria continuous from sides to front, narrowly interrupted at middle; lateral submarginal stria continuous at side, curving inward, ending freely behind eye; anterior submarginal stria present, straight across front (not recurving posterad at ends), ending freely behind eye; median pronotal gland openings present between free ends of submarginal striae, about 4 puncture widths from anterior margin; elytron with two complete epipleural striae; all dorsal striae broadly but shallowly impressed, crenulate, inner and outer subhumeral striae complete in basal two-thirds, obscured by coarse punctures toward apex, striae 1-5 reaching base, progressively more abbreviated apically, 5th stria fragmented over much of its length, sutural stria complete; elytra with very conspicuous ground punctation, as on pronotum, coarser punctures uniformly interspersed in interstriae; prosternal keel truncate at base, carinal striae complete, united in a narrow anterior arch; secondary carinal striae present for short distance behind prosternal gland openings; prosternal lobe short, but evenly rounded, reaching hypomeron at sides, marginal stria complete on anterior portion, obsolete at sides; mesoventrite straight to very weakly projecting at middle, marginal stria complete; mesometaventral stria detached at sides from lateral metaventral stria, displaced anterad and parallel to marginal mesoventral stria; lateral metaventral stria beginning behind mesometaventral suture, extending posterolaterad toward outer third of metacoxa; postmesocoxal stria recurved to mesepimeron; metaventral disk without coarse punctures in middle, but with large punctures at sides; 1st abdominal ventrite with single lateral stria, with increasingly coarse punctures toward posterior margin, especially near ends of lateral striae; abdominal ventrites 2-4 with nearly uniform series of large, shallow punctures along posterior margins; propygidium with uniform coarse punctures separated by one-half their widths; pygidium with coarse punctures smaller, denser; marginal stria complete, constituted by a series of deep confluent punctures; protibia 4-dentate, with small marginal spines.
