The arenga species group, hitherto consisting of three species, Colocasiomyia arenga, C. pararenga and C. sagittata, is separated from the genus Colocasiomyia, and established as the new genus Arengomyia Yafuso and Toda, gen. nov. Of the three species, C. pararenga Okada, 1990 is synonymized with C. arenga (Okada, 1987). A new species, Arengomyia xanthopleura Yafuso and Toda, sp. nov., is also described. Supplementary descriptions and revisions of some morphological characters are also provided for the known species.
