Abstract
Trictenotomidae, one of the most charismatic and enigmatic groups of beetles, known for their large size and distinctive mandibles, is widely distributed throughout tropical and subtropical Asia. New species are continually being discovered, and the known range of the group has been expanded considerably by the discovery of Autocrates maqueti Drumont in the Korean Peninsula, ~2,000 km from its previously known distribution in the Chinese mainland highlands. A comprehensively sampled multigene phylogenetic tree of Trictenotomidae, including all six species of Autocrates and five species of Trictenotoma, was reconstructed using multigene data. Using the resulting phylogeny, we performed divergence time estimation, biogeographical assessments, and molecular species delimitation. All six known species of the genus Autocrates were found to be valid in all four molecular species delimitation scenarios, indicating the need for further taxonomic research on these poorly understood taxa. The A. maqueti population in South Korea forms a genetically distinct clade in all genetic analyses, suggesting that it is a natural distribution rather than a result of anthropogenically driven spread. The Korean A. maqueti population is likely to have been isolated since ~1.8 Mya, when the Yellow Sea was still a landmass, highlighting the need for targeted conservation measures in South Korea.
期刊介绍:
The Zoological Journal of the Linnean Society publishes papers on systematic and evolutionary zoology and comparative, functional and other studies where relevant to these areas. Studies of extinct as well as living animals are included. Reviews are also published; these may be invited by the Editorial Board, but uninvited reviews may also be considered. The Zoological Journal also has a wide circulation amongst zoologists and although narrowly specialized papers are not excluded, potential authors should bear that readership in mind.
