Diagnosis.

Males of L. swinhoei could be distinguished from related species by following characters: 1) mandibles incurved at basal 1/3, straight along the midlength and incurved apically; 2) apical teeth bifurcated; major mandibular tooth located at basal 1/3, triangular, not flat on both sides; 3) elytra metallic luster at disc and along the suture, reddish to brownish; less punctate and without any yellowish setae. The females of most species in Lucanus are not easy to distinguish due to their significant similarities in morphology. Typical female of L. swinhoei could be identified by the following subtle differences: elytra without a marked pubescence, metasternum not densely hairy and the canthi not markedly outside of the eyes.
