Two new species of the genus Hemirrhaphes Candèze, 1878, H. johorensis sp. nov., and H. laoticus sp. nov., are described and illustrated, and new data on H. ferrugineus Candèze, 1896, and H. notabilis Candèze, 1878 are provided. In total, we consider 6 species as members of the genus Hemirrhaphes: H. apicalis Schwarz, 1900, H. bivittatus Fleutiaux, 1905, H. ferrugineus Candèze, 1896, H. johorensis sp. nov., H. laoticus sp. nov., and H. notabilis Candèze, 1878. It is argued that species of Hemirrhaphes are phylogenetically closer to species of the genus Zorochros than to those of the genus Arhaphes, in which they were repeatedly placed by various earlier authors.
