Median male. 139. Minor male. Scale bar= 10 mm. Description. Major male. Body brownish, head and pronotum covered with vestiture of short, yellowish setae; head, including widest region of mandibular bases, 3× width of pronotum and elytra. Head mainly brownish, surface covered with vestiture of short, yellowish setae; mandibles strongly incurved at basal 1/3, straight along midlength and apex; major inner mandibular tooth located approximately halfway to apex, triangular, sharply pointed, not inflated on either side, a single small inner mandibular tooth located below major inner mandibular tooth; usually 4–5 small inner mandibular teeth located between major mandibular tooth and apical forks; apical mandibular forks strongly developed, widely open anteriorly, upper branches of apical fork 2× length of lower apical fork branches; anterolateral ridges of head weakly rounded, posterolateral margin of head convex, slightly wider than anterolateral ridges; clypeolabrum developed, short trapezoidal, labrum triangular, weakly protruding meson and lateral margins. Pronotum brownish; surface covered with vestiture of short yellowish setae; weakly convex at apex and base, somewhat protruding along midlength; 0.3× width of head and mandibles; prothoracic tibiae yellowish to orange, each bearing five small but well-developed spines from apex to basal 1/3; mesothoracic tibiae yellowish, each bearing two spines at midlength; metathoracic tibiae bright reddish, each bearing a single poorly developed spine at basal 1/3. Elytra yellowish to brownish, apical elytra covered with vestiture of short yellowish setae; weakly metallic; slender, widest at apical 1/3, strongly narrowed at basal 1/3. No median male material examined. Minor male as major male except: head with mandible weakly incurved at basal 1/3, straight anteriorly; major inner mandibular tooth weakly developed, single-pointed and not triangular; <3 poorly developed small inner mandibular teeth located below or above major tooth. Genitalia: basal piece 0.45× length of entire aedeagus; apical flagellum weakly enlarged, flagellum 0.45× length of entire aedeagus; aedeagus stout, incurved at basal 1/3, triangular distally. Female. Unknown. Distribution. China ( Yunnan ). Phenology. Adult specimens of L. fujitai were collected during early May to early June. Natural history. Typical plants for this species are still unknown. Lucanus fujitai appears to be weakly attracted to light. Adult longevity is 20 days. Collecting methods. Light-trap collected.
