Abstract

A new species of oribatid mites (Oribatida) phoretic on the beetle, Macrolinus batesi (Coleoptera, Passalidae) is described from Sumatra, Indonesia. Graptoppia (Stenoppia) royi sp. nov. (Oppiidae) differs from G. (S.) italica by the smaller body size, the presence of thin transcostula and the absence of costulae. Data on oribatids phoretic on passalid beetles are summarized; nine identified oribatid species (from 19 beetle species) are listed.
