A new species of acarid mite was collected in 1980 from rice bran residues and broken rice in a cooperative rice mill at Dewi Ratih, Tulungagung, East Java. The female and male of the new mite, Madaglyphus javensis, are described, and notes are given on the tritonymph, protonymph and larva. The definition of the previously monotypic genus Madaglyphus is modified slightly to accommodate this second species. The main characters differentiating M. javensis sp. n. from M. legendrei Fain are tabulated.
