Body length 33.3–48. 7 mm (♂); 25. 9 mm (♀).

Description. Major male. Head and pronotum reddish to brownish, covered with a thick vestiture of long, yellowish-amber setae; elytra covered with vestiture of short, yellowish-amber setae; elytra brownish, lighter than color of head and pronotum, having black stripes along sutural and lateral margins; head, including mandibles, 1.2× width of pronotum and elytra. Head reddish to brownish; mandibles weakly incurved along basal 1/3, straight at middle and weakly incurved along apical 1/3; major inner mandibular tooth located 1/3 distance to apex, triangular protruding forward and inflated on either side, 3–5 separated, small inner mandibular teeth located below major inner mandibular tooth; 2–3 sharp small inner mandibular teeth located between major tooth and mandibular apex; apical mandibular fork strongly developed, widely open from front, upper branch of apical fork 2× length of lower apical branch fork; lateral ridges of head subparallel, weakly rounded, evenly convex at end of head; clypeolabrum weakly developed, flattened, single-pointed along midlength. Pronotum brownish with metallic luster, usually darker than head; straight along apex and basal 1/3, weakly rounded at midlength; length 0.8× of head and mandibles; prothoracic tibiae yellowish-amber, bearing five well developed spines from apex to midlength; mesothoracic tibiae bright yellowish, each bearing two spines along midlength; metathoracic tibiae bright yellowish, black along apex, smooth and without any spines along basal 1/3. Elytra brownish but less mat than head and pronotum, covered with a thin vestiture of short, yellowish-amber setae, less setose than head and pronotum; lateral elytral margins and suture blackish; oval, widest along apical 1/3, strongly narrow along basal 1/3. Median male as major male except: head with major inner mandibular tooth single-pointed, weakly triangular pointing forward; <4 small inner mandibular teeth located below major tooth, 1–2 sharp small inner mandibular teeth located between major tooth and mandibular apex. Minor male as major and median males except: head with major inner mandibular tooth weakly developed to absent, if present, single-pointed and not triangular; <4 small inner mandibular teeth located within mandibular margins. Genitalia. Ventral plate of 9th abdominal segment abruptly widened behind cephalic base and constricted before caudal expansion; basal piece usually well defined, 0.4–0.5× length of entire aedeagus; apical flagellum enlarged, flagellum 1.1× length of aedeagus; aedeagus slender, incurved at basal 1/3, triangular distally.

Female. Body dark brownish, covered with vestiture of long yellowish-amber setae; usually smaller than major and median males, subequal in length or larger than minor male. Head brownish; surface clearly punctate; mandibles incurved along basal 1/3 and apical 1/3; mandibular tooth weakly developed, asymmetrical; right mandibular tooth triangular; left mandibular tooth smooth; preocular and postocular margins weakly developed, not forming acute angle or protruding apically; clypeolabrum weakly developed, triangular, single-pointed at middle. Pronotum brownish, with metallic luster; obscurely punctate; prothoracic tibiae reddish, punctate, each bearing four spines from apex to midlength; distal two spines strongly developed; prothoracic tibiae 1.2–1.4× width of mesothoracic and metathoracic tibiae; mesothoracic tibiae reddish to yellowish-amber, each bearing a single spine along midlength; metathoracic tibiae reddish to yellowish-amber, bearing a single spine along basal 1/3. Elytra with apices brownish to black, disc with metallic luster; oval, widest at apical 1/3, strongly narrow along basal 1/3.
