Four eriophyid mite species were collected on plants during field survey in Egypt. Abacarus sacchari ChannaBasavanna is recorded for the first time from Egypt and a supplementary morphological description and illustrations are given. A new species, Aculodes sacchari sp. nov., is vagrant in grooves on the inner surface of the leaves of Saccharum officinarum L. (Poaceae) and no apparent symptoms were observed. Two other new species are described: Aculus glinus sp. nov., causes deformations on stems and leaves of Glinus lotoides L. (Molluginaceae), and Aceria nodiflorae sp. nov., is vagrant on leaves and flowers of Phyla nodiflora (L.) Greene (Verbenaceae) and no apparent symptoms were observed. Both adult sexes and immature stages are described and illustrated for all species.
