Systematic revision and biogeography of the endemic Lucanus kanoi species complex (Coleoptera, Lucanidae) from Taiwan, with the description of a new subspecies

In this study, the taxonomic status of the Lucanus kanoi species complex is examined through a comprehensive systematic revision, and the phylogenetic relationships among its constituent taxa are investigated. Three taxa are analyzed: L. kanoi, L. piceus, and L. ogakii. Although closely related, the results support the recognition of each as a distinct species-level taxon.

Specifically, L. piceus stat. nov. is elevated to full species status, rather than being treated as a subspecies of L. kanoi. Furthermore, a new subspecies, L. kanoi kavulunganus subsp. nov., is described based on consistent morphological, biogeographical, and molecular evidence.
