ABSTRACT: The Oriental genus Hygiella Mesnil is revised: three species are described as new, Hygiella angustifrons sp. nov., Hygiella luteipes sp. nov. and Hygiella proclinata sp. nov., and two known species are re-described, Hygiella nigripes Mesnil and Hygiella pygidialis Mesnil. A key to these five species is provided. The host of H. proclinata, Phyllium siccifolium (Linnaeus) (Phasmatodea: Phylliidae), is recorded for the first time as a host of the Tachinidae. The systematic position of Hygiella is discussed and the genus is placed in the tribe Acemyini (Exoristinae) based on the structure of the male terminalia.
