Abstract
Six species of macrochelid mites were collected from scarabaeid dung beetles in Sempu Island, East Java, Indonesia. Of these, one species, Macrocheles insulicola was described as new to science. The remaining five species were Glyptholaspis asperrima (Berlese, 1905), Neopodocinum subjaspersi Hartini and Takaku 2003, M. dispar (Berlese, 1910), M. entetiensis Hartini and Takaku 2005, and M. jabarensis Hartini and Takaku 2003.
