0395879AFFF83469FF42E195FDA0B133.taxon	diagnosis	Differential diagnosis. The new species is most closely to Lucanus boileaui Planet, 1897, but the following set of external and genital characters will help to recognize this new species precisely from L. boileaui: 1) whole mandible relatively straight (Fig. 1 A, C), instead of relatively curve (Fig. 1 E, G, I); 2) in medium and large sized males, basal tooth of mandible not tilted upward significantly, without apex bifurcate horizontally (Fig. 2 A), rather than basal tooth tilted upward and with apex bifurcate horizontally significantly (Fig. 2 B – C); 3) clypeolabrum with apex truncate or rounded (Fig. 3 B, E), instead of with apex sharp (Fig. 3 G, J); 4) in medium and large sized males, anterior ridge of head slightly raised at middle (Fig. 2 A), rather than anterior ridge not raised at middle in most individuals (Fig. 2 B – C); 5) the inside of all tibiae orange-yellow (Figs. 1 B; 10 D), instead of the inside black (Fig. 1 F, H, J); 6) base of apex branches of protibia not extend (Fig. 3 C), instead of the base strongly extend (Fig. 3 H, K); 7) ventral plate of the abdominal segment IX with membranous stripe shorter and narrower, from near apex to apical 1 / 3 (Fig. 4 D), rather than with membranous stripe longer and wider, from apex to about half length of the plate (Fig. 4 H, L); 8) penis obviously shorter than paramere (Fig. 6 A), instead of slightly shorter than paramere or as long as the paramere (Fig. 6 D, G); 9) flagellum about 7 times as long as aedeagus (Fig. 5 A), rather than usually about 8 – 10 times as long as aedeagus (Fig. 5 B – C); 10) strut of aedeagus longer, with an enlarged part distinctly behind the distal end (Fig. 6 C), rather than strut shorter, without enlarged part (Fig. 6 F, I). Due to the lack of sufficient specimens, there may be some variation in these distinguishing features of the new species, which needs to be verified by subsequent more specimens. Moreover, this new species is somewhat similar to L. dybowski dybowski (belonging to the L. maculifemoratus group), but there are significant differences between the two in abdominal ventrite IX and aedeagus. Abdominal ventrite IX of L. dybowski dybowski without a membranous stripe along the midline; flagellum short, about as long as aedeagus, apex enlarged. These features are also the main basis for distinguishing the males of the L. boileaui group and the L. maculifemoratus group (Huang & Chen 2010; Qi et al. 2023).	en	Lin, Xin, Su, Rong-Xiang, Xin, Fei-Yi, Liao, Zhi-Yu, Lu, Huang-Hui, Liu, Xian-Zhou, Song, Hai-Tian (2024): Lucanus qizhihaoi, a new stag beetle from Wuyishan National Park of Fujian, China (Coleoptera: Lucanidae: Lucaninae).

0395879AFFF83469FF42E195FDA0B133.taxon	etymology	Etymology. The new species is named after Mr. Zhi-Hao Qi (Ấâă), a young entomologist from Wuyishan City, Fujian Province, China, who collected and provided the holotype specimen of the new species for our study.	en	Lin, Xin, Su, Rong-Xiang, Xin, Fei-Yi, Liao, Zhi-Yu, Lu, Huang-Hui, Liu, Xian-Zhou, Song, Hai-Tian (2024): Lucanus qizhihaoi, a new stag beetle from Wuyishan National Park of Fujian, China (Coleoptera: Lucanidae: Lucaninae).

0395879AFFF83469FF42E195FDA0B133.taxon	discussion	Remarks. This new species should be assigned to the Lucanus boileaui group based on the external and genital characters (sensu Huang & Chen 2010). The new species was first discovered on October 2 nd, 2023, when Xin Lin and Huang-Hui Lu, hiking with other hikers, accidentally picked up a large sized mutilated body of this species on the top of the Mt. Xianglushan at an altitude of 1900 m. Xin Lin took photos at the scene (Fig. 10 C – D) and brought the head back. At that time, we speculated that this species is closest to L. boileaui, perhaps a new subspecies of L. boileaui or a separate new species. At 8 a. m. on July 13 th, 2024, we formed a team of four people with hiking bags carrying dry food, water, gasoline generators and tents from the foot of the Mt. Xianglushan at 1080 m, and reached the camping position at an altitude of 1700 m at around 4 p. m. At night, we set up a light tent trap, using a 250 W high-pressure mercury lamp to lure. At the same time, five simple light traps using 11 W purple lights were set up at an altitude of 1695 m to 1780 m. After a night of light trapping, we collected L. wuyishanensis and L. fortunei, but did not found any of this new species. At about 11 a. m. on July 14 th, we climbed to the top of the Mt. Xianglushan and began collecting insect specimens and taking photos (Figs. 9 B – D; 11 A – B). During this time, we witnessed a male Lucanus species flying to the top, but failed to collect it. Before returning, we decided to search the location nearby, where the carcass of the new species was found last year. Fortunately and surprisingly, Zhi-Hao Qi found a small male individual of the new species dying in the sun on a large rock (Figs. 9 D; 10 A – B). A female was subsequently collected, but later identified as L. parryi parryi. In summary, we believe that L. qizhihaoi Lin, Su, Xin & Song, new species, as most other Lucanus species, has a habit of flying to the top of the mountain. In addition, since only one night of light trapping was performed, the phototaxis of this new species is unclear.	en	Lin, Xin, Su, Rong-Xiang, Xin, Fei-Yi, Liao, Zhi-Yu, Lu, Huang-Hui, Liu, Xian-Zhou, Song, Hai-Tian (2024): Lucanus qizhihaoi, a new stag beetle from Wuyishan National Park of Fujian, China (Coleoptera: Lucanidae: Lucaninae).
