REDESCRIPTION OF LECTOTYPE

Length: 8.0 mm; length of elytra: 5.9 mm; width: 4.8 mm. Body oval, dorsal surface brown with greenish shine, ventral surface metallic-green, completely shiny and glabrous, except for a few small setae on the head (habitus Fig. 1A ).

Labroclypeus subtrapezoidal, little wider than long, widest at base, lateral margins unevenly convex and convergent to moderately rounded anterior angles, lateral border and ocular canthus producing an indistinct blunt angle, margins weakly reflexed, anteriorly shallowly sinuate medially; entire surface weakly convex, shiny, finely and densely punctate, with a few short, erect setae anteriorly; frontoclypeal suture feebly impressed and weakly curved medially; smooth area in front of eye approximately twice as wide as long; ocular canthus short and sharply pointed, finely and sparsely punctate, with a short single terminal hair. Frons with fine, moderately dense punctures, glabrous except for a few setae beside eyes. Eyes small, ratio of diameter/interocular width: 0.6. Antenna brown, with nine antennomeres, antennomeres 3-5 fused; club with three antennomeres, a little longer than the remaining antennomeres combined.

Pronotum subtrapezoidal, widest at base, lateral margins very weakly and evenly convex and strongly convergent anteriorly, anterior angles moderately produced but sharp, posterior angles blunt, anterior marginal line complete, margin weakly convexly produced medially; basal marginal line fine and widely interrupted medially; surface sparsely and finely punctate, glabrous; anterior and lateral borders sparsely setose. Scutellum wide, triangular, apex sharp, with fine and moderately dense punctures, glabrous.

Elytra oblong, widest at middle, with convex semicircular declivity distinctly separated from apical portion of elytra, apical interior angle rightangled, apical external angle blunt but moderately rounded in the tip, apical border straight; striae not impressed and impunctate, almost invisible, intervals completely flat, with fine, moderately dense punctures, glabrous; epipleural edge robust, ending at the external apical angle of elytra, epipleura very sparsely setose (setae in lectotype lost).

External angle of metacoxa posteriorly produced forming a sharp tooth, lateral marginal line in posterior half slightly reflexed; mesal process of metacoxa slender and longer than remainder metacoxa and its ventral surface longitudinally convex.Ratio of length of metepisternum/metacoxa:1/2.0. Pygidium weakly

convex, very finely and sparsely punctate, without smooth midline, punctures without microscopic setae and with a few long setae apically.

Metatibia moderately wide and long, widest at apex, ratio width/length: 1/3.4, dorsally longitudinally convex, with two groups of spines, basal one at one third, apical one at two thirds of metatibial length; lateral face longitudinally convex, with dense and fine longitudinally impressed punctures, glabrous; ventral edge not serrate, with five strong spines equidistant from each other, medial face not punctate.Tarsomeres dorsally smooth, ventrally with sparse, short setae; metatarsomeres ventrally with a strongly serrated ridge, beside which is a strong longitudinal carina, first metatarsomere a little shorter than the two following segments combined and a little longer than the upper tibial spur.

Aedeagus: Figure 1 B-D.

VARIATION

Length: 7.9-8.5 mm; length of elytra: 5.8-6.1 mm; width: 4.5-5.3 mm. The female has the antennal club slightly shorter.
