| Abstract: | Three new species of the Stegana (Oxyphortica) convergens species group are described from South China: S. (O.) gonglui Wang and Chen, sp. nov., S. (O.) xiaoyangae Zhang and Chen, sp. nov., and S. (O.) zhulinae Wang and Chen, sp. nov. The diagnosis of S. (O.) setifrons is revised. A key to all eight species of this group is provided. The phylogenetic relationships among the eight species of this group are reconstructed using DNA sequences of the mitochondrial COI gene (cytochrome c oxidase, subunit I). The intra- and interspecific pairwise Kimura’s two-parameter (K-2P) distances for these species are summarised. Moreover, 35 COI sequences of the eight convergens species show the presence of 30 species-specific base substitutions in 28 nucleotide sites in the character-based analysis. www.zoobank.org/urn:lsid:zoobank.org:pub:8AC2D398-96F2-4EE5-AE0D-16B8761BD55D |
