title: A new species group in the genus Dichaetophora Duda (Diptera: Drosophilidae) based on a phylogenetic analysis, with descriptions of four new species from China.
abstract: A new species group, the sinensis group, is established within the genus Dichaetophora, based on a phylogenetic analysis of 37 adult morphological characters from 26 drosophilid species, including ten known species of Dichaetophora; four newly described species (Di. abnormis, Di. hainanensis, Di. bicornis, and Di. sinensis spp. nov. from China); and some representatives of related genera (Drosophila, Hirtodrosophila, and Scaptomyza).
