Redescription (holotype). Length: 7.4 mm, length of elytra: 5.1 mm, width: 4.4 mm. Body oval, dorsal face light reddish-brown and dull, elytra partly with iridescent shine, head shiny, with dense, erect, moderately long setae, antenna yellow.

Labroclypeus subrectangular, little wider than long, widest at middle, lateral margins convex and moderately convergent the base and to moderately rounded anterior angles; lateral margin and ocular canthus producing a blunt angle, margins moderately reflexed; anterior margin distinctly emarginate medially; surface flat, finely and densely punctate, with dense, moderately long, erect setae; frontoclypeal suture weakly impressed and angled medially; smooth area in front of eye approximately twice as wide as long; ocular canthus short and fine (1/4 of ocular diameter), finely densely punctate, with 2–3 terminal setae. Frons with fine and coarse, dense punctures, with dense, moderately long, erect setae. Eyes moderately large, ratio of diameter/interocular width: 0.67. Antenna composed of 9 antennomeres, club with three antennomeres, strongly reflexed, twice as long as remaining antennomeres combined. Mentum anteriorly elevated and flattened.

Pronotum subtrapezoidal, widest at base, lateral margins in basal half straight and subparallel, in anterior half strongly convex and convergent anteriorly; anterior angles weakly produced and blunt; posterior angles blunt; anterior margin weakly convex, marginal line widely interrupted medially; basal margin without marginal line; surface coarsely and densely punctate, with moderately long, erect setae mixed with short adpressed ones; anterior and lateral margins with dense setae. Hypomeron carinate, not produced ventrally. Scutellum wide, triangular, with coarse and moderately dense punctures, with short adpressed setae.

Elytra oval, widest at middle, striae distinctly impressed, finely and densely punctate; intervals convex at middle, with fine, dense punctures concentrated along striae, on middle of interval almost impunctate; intervals with dense, moderately long setae being directed posteriorly; epipleural margin robust, ending before rounded external apical angle of elytra, epipleura densely setose, apical border chitinous, without a rim of microtrichomes.

Ventral surface shiny along middle, dull at sides, metasternum and metacoxa with fine and moderately dense punctures, sparsely setose; metacoxa with fine adpressed setae, except for a several long setae laterally. Mesosternum between mesocoxae narrower than mesofemur. Ratio of length of metepisternum/metacoxa: 1/1.63. Abdominal sternites, in addition to generally distributed fine and moderately dense punctures, each with a distinct transverse row of coarse punctures each bearing a short and robust seta, otherwise with fine dense setae; penultimate sternite apically without distinct chitinous border. Pygidium strongly convex, dull, with fine, dense punctures and dense, long setae.

Legs moderately wide and short; femora with two longitudinal rows of setae, finely and moderately densely punctate; metafemur shiny, anterior margin acute, lacking an adjacent serrated line, posterior ventral margin straight, not widened in apical half, smooth, dorsal posterior margin also not serrate, finely setose. Metatibia moderately wide and short, widest at apex, ratio width/length: 1/2.8; dorsal margin sharply carinate, with two groups of spines, basal one at one third, apical one two thirds of metatibial length; basally with a few fine setae; lateral face longitudinally convex, with dense and coarse punctures, and moderately long setae in the punctures; ventral margin serrate, with three equidistant robust setae; medial face coarsely but sparsely punctate and with sparse minute setae in punctures, apex interiorly near tarsal articulation bluntly truncate and shallowly concave. Tarsomeres impunctate dorsally, ventrally with sparse, short setae; metatarsomeres ventrally glabrous, with a strongly serrated ridge ventrally and a smooth subventral longitudinal carina; first metatarsomere dorsally and laterally also moderately carinate, distinctly longer than following two tarsomeres combined and little longer than dorsal tibial spur. Protibia moderately long, bidentate, external margin bluntly extended medially.All claws symmetrical, feebly curved and long, with normally developed basal tooth.
