Body length 45.5–62.3 mm (♂); 34.1.4– 36.5 mm (♀).

Description. Major male. Body brownish to reddish, surface strongly metallic, head, including widest region of mandibular bases, 2.2× width of pronotum and elytra. Head brownish to somewhat reddish, less metallic, surface covered with vestiture of significant, long yellowish-amber setae; mandibles straight at base and midlength, incurved at apical 1/3; major inner mandibular tooth located halfway toapex, sharply triangular protruding forward and poorly inflated on either side,>6 small inner mandibular teeth located below major inner mandibular tooth, <6 small inner mandibular teeth located above major inner mandibular tooth but located closely behind apical mandibular forks; apical mandibular forks well developed, widely open anteriorly, upper branches of apical fork 2× length of lower apical fork branches; anterolateral ridges of head well developed, posterolateral margin of head evenly convex, slightly wider than anterolateral ridges; clypeolabrum well developed, trapezoidal, labrum triangular, protruding along midlength and labral margins. Pronotum brownish to reddish, somewhat metallic, color usually darker than head; surface covered with vestiture of dense, short yellowish-amber setae; pronotum convex at apex and base, significantly protruding along midlength; 0.5× width of head and mandibles; prothoracic tibiae bright reddish to orange, each bearing>5 weakly developed but sharp spines from apex to basal 1/3; mesothoracic tibiae bright reddish, each bearing 2–3 spines along midlength; metathoracic tibiae bright reddish, each bearing a single poorly developed spine at basal 1/3. Elytra reddish, surface smooth and strongly metallic; slender, widest at apical 1/3, strongly narrow at basal 1/3. Median male as major male except: head with mandibles weakly incurved at apex 1/3; <6 small inner mandibular teeth located below major tooth. Elytra surface usually also covered with vestiture of short, yellowish setae. Minor male as major and median males except: head with mandibles reddish; major inner mandibular tooth weakly developed to absent, single-point and not triangular; <6 small inner mandibular teeth located below or above major tooth. Genitalia. Ventral plate of 9th abdominal segment constricted before caudal expansion; basal piece usually clearly defined, 0.4× length of entire aedeagus; apical flagellum weakly enlarged, flagellum 0.5× length of entire aedeagus; aedeagus short, incurved at basal 1/3, triangular distally.

Female. Body black, surface metallic, oval, usually smaller than major and median males, subequal in length to, or larger than minor male. Head black, surface punctate; mandibles incurved; mandibular tooth well developed, asymmetrical; right mandibular tooth triangular, that of left mandibular bearing two significant denticules; preocular and postocular margins welly developed, forming acute angle, protruding apically; clypeolabrum weakly developed, triangular, single-pointed at middle. Pronotum black, surface metallic; obscurely but densely punctate; anterior pronotum significantly enlarged and incurved, as wide as or 1.2× width of posterolateral pronotum; prothoracic tibiae black, each bearing five spines from apex to midlength; distal two spines poorly developed; prothoracic tibiae 1.3× width of mesothoracic and metathoracic tibiae; mesothoracic tibiae black, each bearing two spines at midlength; metathoracic tibiae black, each bearing a single spine at basal 1/3. Elytra black, surface shinning and somewhat metallic, concolorouswith head and pronotum; oval, widest at apical 1/3, strongly narrow at basal 1/3.

Distribution. China (Guangxi (Baise City, Ceng-Wang-Lao-Shan Mt.)).

Phenology. Adult specimens of L. cenwanglaoshanus were collected in mid-July.

Natural history. The typical host plant for this species is still unknown. Adult longevity is 12–15 days. Lucanus cenwanglaoshanus has been collecged at a light-trap. All specimens collected from Cen-Wang-Lao-Shan Mountain were labelled as “collected by the light-trap”.

Collecting methods. Light-trap collected.
