Diagnoses and a key for seven macrochelid mites species of two genera, Macrocheles and Holostaspella, associated with scarabaeid beetles in Sumatra are given. Those species include one new species, Macrocheles sukaramiensis sp. nov., and three species, Macrocheles oigru, M. kraepelini, and Holostaspella berlesei, recorded from Sumatra for the first time. The new species is described in detail on the basis of materials collected from scarabaeid beetle Catharsius molossus in the Province of Sumatera Barat, Sumatra.

Ten mite species of the genus Macrocheles (Acari: Macrochelidae) were collected from the body surface of dung beetles (Scarabaeidae) in Papua, Indonesia, providing the first record of the genus for the area. Of these, five species, Macrocheles erniae, M. kojimai, M. manokwariensis, M. timikaensis, and M. woroae, were described as new to science. The remaining five species were M. agilis, M. borealis, M. limue, M. merdarius, and M. sp. aff. glaber.

Seventeen species of macrochelid mites belonging to the genera Glyptholaspis and Macrocheles are recorded from Sulawesi, Indonesia. They were all collected from dung beetles (Aphodiinae, Scarabaeinae). Except for Macrocheles kraepelini, all the species are recorded from Sulawesi for the first time. Six species, i.e., M. convexus sp. nov., M. donggalensis sp. nov., M. persimilis sp. nov., M. pilosellus sp. nov., M. simulans sp. nov., M. variodecoratus sp. nov., are new to science. A key to 55 species of macrochelid mites recorded from Indonesia is also provided.

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 Takaku 2003, M. dispar (Berlese, 1910)

Twenty one species of macrochelid mites belonging to the genera Glyptholaspis Holostaspella, and Macrocheles, were collected in the Philippines. Of these, 3 species were described as new to science, and 9 species were recorded from the Philippines for the fi rst time. In total 23 species are known from the Philippines to date, including Holostaspella stenaspis Krantz, 1967 and Glyptholaspis cariasoi De Jesus and Rueda, 1990, which were not collected in this research.
