Key to females of the Lucanus boileaui group

1. Ventral surface of mesofemur and metafemur with orange stripes ( Fig. 5F ); spermatheca strongly hooked, the position of apex perpendicular to front the middle length of spermatheca ( Fig. 7O ); spermathecal duct long ( Fig. 7M ), about 5 times as long as spermatheca.................................................................. Lucanus boileaui Planet, 1897

– Ventral surface of mesofemur and metafemur black ( Fig. 5B ), without orange stripes; spermatheca weakly hooked, the position of apex perpendicular to behind the middle length of spermatheca ( Fig. 7E ); spermathecal duct much short ( Fig. 7C ), nearly as long as spermatheca................................................................................... 2

2. Canthus with anterior and posterior angles well-developed, clearly defined ( Fig. 6H ); spermatheca not sclerotized, less hooked (refer to p. 22 in Huang & Chen, 2017)......................................... .. Lucanus ludivinae Boucher, 1998

– Canthus with anterior and posterior angles weakly developed, not defined ( Fig. 6C ); most part of spermatheca not sclerotized, weakly sclerotized at apex only, more hooked ( Fig. 7E )............ Lucanus jiaozishanus Qi, He, Su & Song, new species
