B76087BEFFA7FFB7FF7C81448019C16E.taxon	discussion	REMARKS. This new species was assigned to the L. brivioi species group (sensu Zhan & Young, 2023).

It well resembles L. brivioi Zilioli, 2003 in general appearance (their aedeagi are also similar to each other, however, there are still differences on the curvatures of the outer margins of penis and the sizes of the flagellum apices), but it can be distinguished by the combination of the following characters (L. brivioi in round brackets). Male: all tibiae and femora with yellowish stripes on dorsal and ventral sides (Figs 11 A, B) (with reddish stripes on dorsal and ventral sides (Fig. 11 C )), labrum more slender (shorter), major inner teeth of mandibles stouter (Fig. 13 A) (more slender (Fig. 13 B )), head with lateral ridges rounded at lateral corners (Fig. 13 A) (obtuse at lateral corners (Fig. 13 B )), ventral plate of segment IX with linear longitudinal membranous stripe along midline of apical expansion (Fig. 14 C) (only with small membranous area in median of apical part). Female: all femora with yellowish stripes on ventral sides (Fig. 11 E) (almost uniformly black (Fig. 11 F )), protibiae with apical branches relatively broader and blunter (Fig. 11 D) (relatively smaller and sharper (Fig. 11 F )), abdominal sternite VIII distinctly emarginate in median of posterior margin (Fig. 14 F) (weakly emarginate in median of posterior margin), hemisternite moderately wide and inner lateral margin of sclerotized part long (Fig. 16 A) (rather wide and inner lateral margin of sclerotized part short (Fig. 16 D )), spermatheca with proximal part moderately to strongly curved inwards (Figs 16 A, C) (straight or weakly curved inwards (Fig. 16 D )).	en	Wang, Chen-Bin (2024): Two new species of Lucanus Scopoli, 1763 (Coleoptera: Lucanidae, Lucaninae) from China.
