Abstract

Three new assassin bug species of the genus Biasticus Stål, 1867 are recognized in Vietnam based on morphological examination, morphometric and molecular phylogenetic analyses, and described as Biasticustaynguyenensis Ha, Truong & Ishikawa, sp. nov., Biasticusgriseocapillus Ha, Truong & Ishikawa, sp. nov., and Biasticusluteicollis Ha, Truong & Ishikawa, sp. nov. The conspecific male and female associations of the new species were confirmed by phylogenetic analyses and DNA barcoding of the mitochondrial 16S rDNA and COI genes. All three new species are presently restricted to the Central Highlands, Vietnam (Kon Chu Rang NR, Gia Lai Province, and Chu Yang Sin NP, Dak Lak Province).

Keywords: Assassin bugs; Indo-China; molecular phylogeny; morphometry; taxonomy.
