Diagnostic description
Length: 1.9–2.2mm, width: 1.6–1.8mm; body elongate oval, depressed, glabrous; head and pronotum metallic greenish to violet-blue, contrasting with metallic blue elytra, pygidia more subtly metallic blue, venter rufopiceous; frons elevated over antennal bases, depressed at middle, ground punctation fine, with few coarse punctures at middle and near vertex, frontal stria present along inner margin of eye, curving inward at front, interrupted at middle, supraorbital stria more or less complete; antennal scape short, club broadly rounded; epistoma truncate apically; labrum about 4×wider than long, weakly bisinuate along apical margin; both mandibles with acute basal tooth; pronotum with sides weakly arcuate to apex, marginal stria complete along lateral and anterior margins, lateral submarginal stria absent, but generally represented by distinct series of submarginal punctures along side, ground punctation of pronotal disk rather conspicuous, coarse secondary punctures present in lateral thirds; elytra with two complete epipleural striae, outer subhumeral stria absent, inner subhumeral stria largely complete, but usually interrupted in basal half, dorsal striae 1–4 complete, 5th stria complete or abbreviated from base with basal puncture, sutural stria present in about apical half, elytral disk with few coarse punctures in apical fourth; prosternum moderately broad, weakly convex, keel weakly emarginate at base, carinal striae complete, subparallel to divergent anterad, separate or united along basal margin; prosternal lobe about one-half keel length, apical margin broadly rounded, marginal stria obsolete at sides; mesoventrite weakly produced at middle, marginal stria complete; mesometaventral stria arched forward at middle, crenulate, detached at sides, inner lateral metaventral stria extending from end of marginal mesoventral stria obliquely posterolaterad toward middle of metacoxa, outer lateral metaventral stria absent, metaventral disk impunctate at middle; abdominal ventrite 1 with single, complete lateral stria, middle portion of disk lacking coarse punctures; protibia 4–5 dentate, the basal one or two denticles weak, outer margin serrulate between teeth; mesotibia with two weak marginal spines; outer metatibial margin smooth; propygidium without transverse basal stria, discal punctures moderately large, ocellate, separated by about half their diameters basally, slightly smaller and sparser posterad; propygidial gland openings evident about one-third from anterior margin, about one-fourth from each lateral margin; pygidium with ground punctation very fine but rather dense in apical half, secondary punctation evident mainly along basal margin. Male genitalia (Figs 12A–D, I–J): T8 about as long as broad, sides subparallel, basal rim weakly explanate, basal emargination broadly rounded, apical emargination inconspicuous, ventrolateral apodemes separated by about one-third maximum T8 width, extending about one-half distad beneath, obsolete in apical half; S8 much longer than T8, divided, inner margins approximate at base, strongly divergent apically, bearing conspicuous fringe of setae along apical one-third, outer margins subparallel to weakly divergent, apical guides well developed in apical two-thirds, narrowly rounded apically; T9 with basal apodemes thin, about one-half total length, T9 apices narrowly subacute, glabrous, ventrolateral apodemes weakly projecting beneath; S9 stem parallel-sided, weakly widened in basal half, head wide, thin, apicolateral points poorly developed, strongly desclerotized along midline, weakly divided apicomedially; tegmen with sides subparallel throughout, very weakly widened near apex, dorsobasal edge projecting, tegmen in lateral aspect more or less straight, weakly curved ventrad at apex; median lobe about one-third tegmen length; basal piece about one-fifth tegmen length.
Remarks
This species is best distinguished by its lack of basal propygidial stria, presence of sublateral pronotal stria, and presence of the apical half of the sutural elytral stria.
