Epidaus batxatensis and Epidaus konkakinhensis, two new species of the genus Epidaus Stål (Insecta: Hemiptera: Reduviidae: Harpactorinae) from Vietnam

The genus Epidaus Stål, 1859 includes 26 valid species, distributed widely in the Oriental and Sino-Japanese realms. Among them, four species, Epidaus bachmaensis Truong, Zhao & Cai, 2006, E. famulus (Stål, 1904), E. longispinus Hsiao, 1979, and E. sexspinus Hsiao, 1979, were recorded and described from Vietnam. In this study, we conduct the examination of species of the genus Epidaus collected from Vietnam based on an integrative taxonomy, including morphological examination, morphometric analyses (Principal Component Analyses), molecular phylogenetic analyses (Bayesian Inference Analyses), and species delimitation analyses (Assemble Species by Automatic Partitioning and Bayesian implementation of the Poisson Tree Processes model). As a result, two new species of the genus Epidaus Stål, 1859, i.e., Epidaus batxatensis Truong, Nguyen & Ha sp. nov. and Epidaus konkakinhensis Truong, Nguyen & Ha sp. nov., are herein discovered and described.
