Zhan. Body length 46.8–66.2 mm( ♂); 36.9 mm( ♀). Description. Major male. Body brownish to black, surface metallic and covered withvestiture of short, yellowish setae. Head, including widest region of mandibular bases, 1.7× width of pronotum and elytra. Head brownish to black, surface, and distal mandibles covered with vestiture of short yellowish setae; mandibles strongly incurved along distal 1/3 and anterior 1/3, straight along midlength; major inner mandibular tooth located approximately 1/4 length of each mandible, sharply triangular and pointing forward;>8 small inner mandibular teeth located above and below major mandibular tooth; apical mandibular forks strongly developed, upper branches of apical fork 1.6× length of lower apical fork branches; anterolateral ridges of head convex, posterolateral margin of head expanded, significantly wider than anterolateral ridges; clypeolabrum stout, trapezoidal; labrum triangular, protruding along midlength. Thorax brownish to black, concolorous with head, surface setose; convex at apex and base, significantly protruding at middle; 0.65× width of head and mandibles; prothoracic tibiae brownish to black, each bearing four slender spines from apex to midlength; mesothoracic tibiae brownish to black, each bearing 2–3 spines along midlength; metathoracic tibiae brownish to black, each bearing two poorly developed spines distally. Elytra brownish to black, usually concolorous with head and pronotum, less setose and metallic along suture; elytral margins slender, widest at apical 1/3, strongly narrow at basal 1/3. Median male as major male except: head with mandibles straight at distal 1/3 and anterior 1/3. Minor male as major and median males except: head with major mandibular tooth weakly developed; posterolateral margins of head subparallel with anterior margins. Genitalia. Basal piece wide and short, 0.5× length of ntire aedeagus; apical flagellum weakly enlarged, flagellum 0.5× length of entire aedeagus; aedeagus stout, incurved at basal 1/3, triangular distally. Female. Body black, surface smooth without setae, metallic shinning metallic; body stout, always smaller than major and median males, sometimes larger than or subequal in length to minor male. Head black; surface punctate and metallic; mandibles flat, straight along midlength and apical 1/3; each mandibular tooth well developed, asymmetrical; right mandibular tooth triangular, that of left weakly 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 smooth; anterior pronotum weakly enlarged, subequal in width to that of posterolateral pronotum; prothoracic tibiae slender and black, each bearing four developed spines from anterior to midlength; distal two spines sharp, well developed; prothoracic tibiae 1.4× width of mesothoracic and metathoracic tibiae; mesothoracic tibiae black, each bearing three spines along midlength; metathoracic tibiae black, each bearing a single spine at basal 1/3. Elytra black, metallic, concolorous with head and pronotum; oval, widest at apical 1/3, strongly narrow at basal 1/3.  Figures 217–223. Habitus of  Lucanus nobilis. 217. Male, dorsal view. 218.
