Body length 45.2–67.8 mm (♂); 28.9–36.2 mm (♀).

Description. Major male. Body reddish to brownish, body surface weakly metallic; head, including widest region at mandibular bases, 2.3× width of pronotum and elytra. Head brownish, surface covered with vestiture of short, yellowish-amber setae; mandibles strongly incurved along basal 1/3 and apical 1/3, straight along midlength; major inner mandibular tooth located approximately 1/3 distance from apex, acutely triangular, not inflated on either side, <6 small inner mandibular teeth located at basal ¼ of mandible; <4 small inner mandibular teeth located behind apical fork; apical mandibular fork strongly developed, widely open anteriorly, upper branches of apical fork 1.6× length of lower apical fork branches; anterolateral ridges of head rounded, well developed, posterolateral margin of head convex, slightly wider than anterolateral ridges, forming blunt angles; clypeolabrum developed, stout, trapezoidal, labrum triangular, weakly protruding at middle. Thorax brownish, weakly metallic, surface punctate and covered with vestiture of short, yellowish-amber setae; slightly convex at apex and base, strongly protruding at middle; 0.5× width of head and mandibles; prothoracic tibiae reddish and slender, each bearing>5 small but well-developed spines from apex to base; mesothoracic tibiae bright reddish, each bearing 2–3 spines along midlength; metathoracic tibiae reddish, each bearing a single poorly developed spine at basal 1/3. Elytra reddish to brownish, usually brighter than head and pronotum, surface smooth and without any visible setae; strongly metallic; slender, widest at apical 1/3, narrow at basal 1/3. Median male as major male except: head with major inner mandibular tooth stout triangular, single-pointed; <5 small inner mandibular teeth located below major tooth. Minor male as major and median males except: head with mandibles straight and weakly incurved apically; major inner mandibular tooth weakly developed to absent, single-pointed, not triangular; <8 poorly developed small inner mandibular teeth located below or above major tooth. Genitalia. Ventral plate of 9th abdominal segment widened behind cephalic base and constricted before caudal expansion; basal piece usually well defined, 0.36–0.47× length of entire aedeagus; apical flagellum weakly enlarged, flagellum as 0.5× length of entire aedeagus; aedeagus stout, incurved at basal 1/3, triangular distally.

Female. Body black, surface metallic, slender, usually smaller than major and median males, subequal in length or larger than minor male. Head black; surface densely punctate; mandibles strongly incurved along midlength and apical 1/3; mandibular tooth well developed, asymmetrical; right mandibular tooth triangular, that of left mandibular smooth and convex along midlength; preocular and postocular margins well developed, forming acute angles, protruding anteriorly; clypeolabrum poorly developed, single-pointed along midlength. Pronotum black, metallic, obscurely but densely punctate; anterior pronotum well enlarged, forming blunt angles, 1.2× width of posterolateral pronotum; prothoracic tibiae black with reddish stripes, each bearing five spines from apex to midlength; distal two spines sharp, strongly developed; prothoracic tibiae 1.3× width of mesothoracic and metathoracic tibiae; mesothoracic tibiae black, each bearing two spines along midlength; metathoracic tibiae black, each bearing a single spine at basal 1/3. Elytra black, metallic, slender, widest at apical 1/3, strongly narrow at basal 1/3.

Distribution. China (Guangxi).

Phenology. Adult specimens of L. hewenjiae were collected from mid-July.

Natural history. Typical plants for this species are still unknown. Lucanus hewenjiae is strongly attracted to light. Adult longivity is around 30 days.

Collecting methods. Light-trap collected.
