Four new species of the genus Dichaetomyia Malloch, 1921 are described from Madagascar as Dichaetomyia aneliyana spec. nov., Dichaetomyia circuita spec. nov., Dichaetomyia factoti spec. nov. and Dichaetomyia pafema spec. nov. The species belong to a group of Dichaetomyia species which are characterized by metallic shiny blue, green or violet body parts. This type of body colouration is known for Dichaetomyia only from species originating from Madagascar. The four new species are members of the subgenus Dichaetomyia Malloch, 1921.
