Body length 30.4–37.7 mm (♂); 30.1 mm (♀).

Description. Major male. Body brownish with metallic luster; body covered with vestiture of short, yellowish setae. Head, including widest region of mandibular bases, 1.2× width of pronotum and elytra. Head brownish, metallic, and setose; mandibles incurved at distal 1/3 and anterior 1/3; each major inner mandibular tooth located approximately 1/4 length of mandible, stout and single-pointed; three small inner mandibular teeth located above and below major mandibular tooth; apical mandibular forks weakly developed, upper branches of apical fork 1.2× length of lower apical fork branches; anterolateral ridges of head rounded, posterolateral margin of head subparallel with anterolateral ridges; clypeolabrum stout, trapezoidal; labrum triangular, protruding along midlength. Thorax brownish, concolorous with head, surface metallic and setose; convex at apex and base, significantly protruding at middle; 0.6× length of head and mandibles; prothoracic tibiae reddish, each bearing approximately four slender spines from apex to midlength; mesothoracic tibiae reddish, each bearing three spines along midlength; metathoracic tibiae reddish, each bearing a single poorly developed spine distally. Elytra brownish, usually darker than head and pronotum, less setose and metallic along suture; elytra slender, widest at apical 1/3, strongly narrow at basal 1/3. Median male as major male except: head with mandibles straight along distal and anterior; major inner mandibular tooth lacking. Minor male as major and median males except: head with mandibles incurved along midlength; major inner mandibular tooth lacking, only two small inner mandibular teeth located at 1/4 of each mandible; apical mandible forks lacking. Genitalia. Basal piece wide and short, 0.4× length of entire aedeagus; apical flagellum weakly enlarged, flagellum subequal in length to entire aedeagus; aedeagus stout, incurved at basal 1/3, triangular distally.

Female. Body black, surface less setose and less shinning than that of male; body stout, always smaller than major and median males, sometimes larger than or subequal to length of minor male. Head black; surface punctate and metallic; mandibles straight along midlength and apical 1/3; each mandibular tooth well developed, asymmetrical; right mandibular tooth triangular, left mandibular tooth sharply convex along midlength; preocular and postocular margins strongly developed, forming acute angles, and protruding anteriorly; clypeolabrum single-pointed. Thorax pronotum always concolorous with head, surface shinning and setose; densely punctate; anterior pronotum well enlarged, subequal in width to that of posterolateral pronotum; prothoracic tibiae slender and black, each bearing four spines from anterior to midlength; distal two spines sharp, well developed; prothoracic tibiae 1.25× width of mesothoracic and metathoracic tibiae; mesothoracic tibiae black, each bearing two spines along midlength; metathoracic tibiae black, each bearing two spines at basal 1/3. Elytra black, metallic, concolorous with head and pronotum; oval, widest at apical 1/3, strongly narrow at basal 1/3.
