Description of Lucanus chengyuani sp. nov. from Taiwan, with a key to the species of Taiwanese Lucanus Scopoli (Coleoptera: Lucanidae)
Abstract
A new species of stag beetle, Lucanus chengyuani Wang & Ko, is described from Taiwan. This is the ninth species of Lucanus in Taiwan, representing L. fortunei species group. Lucanus chengyuani is the third species having diurnal flight behavior in Taiwan. Its habitat-associated characters and possible convergent adaptation to the habitat shift are discussed.
... Lucanus Scopoli, 1763 is the type genus of the family Lucanidae (Coleoptera) with members occurring in the Nearctic, Oriental and Palearctic regions; however, it reaches its highest diversity in eastern Asia. Since the three milestone books of "Stag beetles of China" by Huang & Chen (2010, 2013, 2017a, nine species have been contributed to Lucanus from Chinese fauna: L. zhanbishengi Wang et Zhu, 2017 from Hunan (Wang & Zhu, 2017), L. zhuxiangi Wang et Zhan, 2018 from Guangdong and Hunan (Wang & Zhan, 2018), L. chengyuani Wang et Ko, 2018 from Taiwan (Wang & Ko, 2018), L. liuweii Huang et Chen, 2019 from Zhejiang (Huang & Chen, 2019), L. cenwanglaoshanus Huang et Chen, 2020 from Guangxi (Huang & Chen, 2020), L. takeoi Adachi, 2020 from Sichuan (Adachi, 2020), L. yulaoensis Lin, 2021 from Taiwan (Lin, 2021), L. moae Qi, 2021 from Sichuan (Qi, 2021), and L. shulini Bian et Zhan, 2021 from Xizang (Bian & Zhan, 2021). In the present paper, we describe and illustrate two new species of Lucanus both from Yunnan Province, Southwest China, under the name of L. niu sp. ...

In the present paper, we describe and illustrate two new species of Lucanus both from Yunnan Province, Southwest China, under the name of L. niu sp. ...
The stag beetle genus Lucanus Scopoli, 1763 (Coleoptera: Lucanidae, Lucaninae, Lucanini) consists of 118 species (without subspecies), of which 64 species known from China. Two new species, Lucanus niu sp. n. and Lucanus zenghuae sp. n., are described from Yunnan Province, Southwest China. Diagnostic characters of the two new species are illustrated and compared with closely related congeners.
... The Lucanidae is a diverse family distributed worldwide with about 110 genera and about 1400 described species (Holloway 2007;Fujita 2010). Lucanus chengyuani was recently described endemic species to Taiwan (Wang and Ko 2018). It is the third species that has a diurnal mate-searching flight behaviour in the genus Lucanus in Taiwan. ...
... The habitat of L. chengyuani is the open area along forest edges with miscellaneous trees and herbaceous plants. The small body size of L. chengyuani likely represents an evolutionary consequence of feeding on lownutritional food in the habitat (Wang and Ko 2018). This is the first report of a complete mitochondrial genome sequence for the species Lucanus chengyuani. ...
We sequenced and assembled the complete mitochondrial genome of Lucanus chengyuani, from the Alishan, Chiayi County, Taiwan. The length of the complete mitogenome of L. chengyuani is 16,926 bp and the mitogenome contains 13 protein-coding, 22 tRNA, and 2 rDNA genes. Nucleotide compositions of the whole mitogenome of L. chengyuani are 38.37% for A, 27.96% for T, 23.03% for C, and 10.637% for G. The AT and GC skewness of mitogenome sequence are 0.157 and -0.368, showing the A-skew and C-skew. The reconstructed phylogenetic relationships of 9 Lucanidae species based on 13 mitochondrial protein-coding genes are highly supported. The clade including Neolucanus maximus and Odontolabis cuvera is sister to the rest of the stag beetle clades, which contains L. chengyuani and L. mazama. Mitogenomic data from this study will provide useful information for further studies for the population genetics, speciation, biogeography, and conservation of L. chengyuani in the future.
... Lucanus Scopoli, 1763 is the type genus of the family Lucanidae Latreille, 1804, most species are distributed in the Palaearctic region, some in the Oriental region and a few in the Nearctic one. China is one of the countries with the greatest species diversity of Lucanus, and in recent years new species have been found continuously, so that currently a total of 66 species are known (Huang & Chen, 2010;2013;2019;2020;Huang, He & Shi, 2011;Wang & Zhu, 2017;Wang & Zhan, 2018;Wang & Ko, 2018;Adachi, 2020;Lin, 2021;Qi, 2021;Bian & Zhan, 2021;Zhan, Zhu & Li, 2022;Zhou et al., 2022;Wang et al., 2023). ...
A new stag beetle is described from Yunnan Province, China: Lucanus jiaozishanus Qi, He, Su & Song, new species. It is the third species of the L. boileaui group which are distributed only in Southwestern China and Northeastern Myanmar. The differences of the new species with the more related taxa (L. boileaui Planet, 1897, L. ludivinae Boucher, 1998 and L. takeoi Adachi, 2020) are discussed. A new synonymy, L. bidentis Schenk, 2013 = L. boileaui, is proposed. Keys to males and females of the L. boileaui group are provided. The variation of males, the female and the host plant of L. takeoi (L. maculifemoratus group) are illustrated for the first time.
Among nine endemic Lucanus beetles in Taiwan, L. datunensis is the island’s smallest and most threatened species. It currently exists as only one population located in tall grasslands
of Mt. Datun in the Yangmingshan National Park. Given the isolated population, unique subtropical grassland, and the threats
resulting from human activities, L. datunensis raises immediate conservation concern for its long-term survival. Phylogenies reconstructed from combined mitochondrial cytochrome
oxidase subunit 1 (1310bps) and nuclear wingless (436bps) genes were resolved and placed L. datunensis as a phylogenetically distinct species sister to L. fortunei from China. All 13 examined individuals of L. datunensis shared just one mitochondrial haplotype suggesting extremely low mitochondrial DNA diversity and a small effective population
size. L. datunensis and morphologically closest L. miwai were distantly related and appear to have evolved in parallel the life history traits of a small body size and diurnal mate-searching
behavior. We hypothesize that these habitat-associated characters are convergent adaptations that have evolved in response
to shifts from forests to grasslands.

Pleistocene glacial oscillations have had profound impacts on the historical population dynamics of extant species. However, the genetic consequences of past climatic changes depend largely on the latitude and topography of the regions in question. This study investigates the effect of Pleistocene glacial periods and the Central Mountain Range on the phylogeography, historical demography, and phenotypic differentiation of a montane forest-dwelling stag beetle, Lucanus formosanus (Coleoptera: Lucanidae), which exhibits extensive mandible variations across mountain ranges in subtropical Taiwan. Analyses of mitochondrial (cox1) and nuclear (wg) loci reveal that L. formosanus originated nearly 1.6 million years ago (Mya) in the early Pleistocene period and consisted of geographically overlapping Alishan and Widespread clades. A drastic population expansion starting approximately 0.2 Mya in the Widespread clade likely resulted from altitudinal range shift of the temperate forests, which was closely tied to the arrival of the Riss glacial period in the late Middle Pleistocene. A ring-like pattern of historical gene flow among neighboring populations in the vicinity of the Central Mountain Range indicates that the mountains constitute a strong vicariant barrier to the east-west gene flow of L. formosanus populations. A geographic cline of decreasing mandible size from central to north and south, and onto southeast of Taiwan is inconsistent with the low overall phylogeographic structures. The degree of mandible variation does not correlate with the expected pattern of neutral evolution, indicating that the evolutionary diversification of this morphological weapon is most likely subject to sexual or natural selection. We hypothesize that the adaptive evolution of mandibles in L. formosanus is shaped largely by the habitat heterogeneity.
