Length: 2.15–2.40 mm, width: 1.75–1.90 mm; body piceous, elongate oval, widest at humeri; head with frons depressed at middle, sides of frontal stria weakly diverging between eyes, complete across front, subangulate at middle; supraorbital represented by a few fragments, disconnected from frontal stria; labrum short, shallowly emarginate apically; left mandible with very weak tooth, right with more prominent basal tooth; pronotal disk with small, irregular, but distinct prescutellar fovea; ground punctation of pronotal disk fine, inconspicuous, with ~15 coarse punctures toward sides, especially anterolaterally; marginal stria more or less complete across front, tending to be fragmented at middle; central portion of anterior margin projecting weakly; lateral submarginal stria complete, curving inward at front, ending freely behind eye; anterior submarginal stria transverse, with ends barely recurved; median pronotal gland openings laterad ends of anterior submarginal stria, about 8 puncture widths from anterior margin; elytron with one complete epipleural stria, outer subhumeral stria present in apical half and with small isolated fragment in basal half, inner subhumeral weak to absent, striae 1-3 complete, 4th stria present in apical half, 5th stria present in apical third, sutural stria present in apical two-thirds; elytral disk with few small punctures subserially arranged along apical margin; prosternal keel broad, shallowly emarginate at base, carinal striae converging strongly to front, joined in narrow anterior arch, free basally; prosternal lobe rather wide, with marginal stria present only near apex; mesoventrite with anterior margin sinuate, weakly projecting at middle, with marginal stria complete or very narrowly interrupted; mesometaventral stria arched forward to basal third of mesoventral disk, continuous with lateral metaventral stria which extends posterolaterally toward middle of metacoxa; central part of metaventral disk impunctate; 1st abdominal ventrite with complete inner lateral stria, abbreviated outer; propygidium with ground punctation fine and sparse, with slightly elongate shallow punctures interspersed, separated by about their diameters; pygidium with fine, very dense ground punctation only, without any coarser punctures; marginal pygidial stria fine, present in about apical half, obsolete on each side to base. Male genitalia (Figs 94C–D, F, H): accessory sclerites present; T8 with sides weakly convergent in basal two-thirds, angled inward to narrow apex, faintly desclerotized at angle, apical emargination narrow, basal emargination broadly angulate, with basal membrane attachment line distad emargination by about one-sixth its depth, ventrolateral apodemes most strongly developed at middle, not meeting beneath; S8 parallel-sided in basal three-fourths, then somewhat abruptly widened to apex, guides well developed only at apex, ventrally separate from base, diverging gradually to near apex, then truncate; T9 with apices subacute, converging, opposed; T10 with halves separate; S9 with stem narrowest one-third from apex, base broad, truncate to weakly emarginate, apex with very small median emargination, apical flanges small and separate, stem markedly desclerotized at base; tegmen with sides broadly rounded, apex subacute, with narrow ‘U’-shaped medioventral process projecting weakly beneath, about one-fourth from base; basal piece about one-half tegmen length; median lobe about one-third tegmen length, with proximal apodemes separate.
