Abstract

There are 29 species or subspecies in genus Hexacentrus occurring in Asia, Africa and Australia. Because of its similar appearance, it is not easy to distinguish them by traditional methods. In this study, we collected samples and sequenced COI genes from wide range. By reconstructing the gene tree, we found one new species, H. formosanus Chen et He sp. nov., from Taiwan. The new species is similar to H. expansus or H. inflatissimus, but differs from the former in male Cu2 vein of left tegmina curved and slender, and spectrum of male left tegmina slender and subsquare; differs from the later by body size smaller and female tegmina narrow and short. The type specimens are deposited in National Museum of Natural Science, Taichung, Taiwan (NMNS). H. japonicus hareyamai is treated as species level, H. hareyamai stat. nov.
