Abstract

The genus Sycanus Amyot & Serville, 1843 includes seventy-two valid species distributed in African and Asian regions. Among those species, eight of them, Sycanus atrocoeruleus Signoret, 1862, S. bifidus (Fabricius, 1787), S. croceus Hsiao, 1979, S. falleni Stål, 1863, S. minor Hsiao, 1979, S. rubricatus Stål, 1874, S. sichuanensis Hsiao, 1979, and S. ventralis Distant, 1919, were described and recorded in Vietnam. In this study, we examined species of Sycanus collected from Vietnam based on external morphology, male genital morphology, and molecular phylogenetic analyses inferred from mitochondrial COI sequences. Consequently, two new species, Sycanus thuathienhuensis sp. nov. and Sycanus taynguyenensis sp. nov., were discovered, described, and illustrated here.
