Fourteen mite species in three genera of the family Macrochelidae were collected from the body surface of dung beetles (Scarabaeidae) in Mt Merapi National Park, Jogyakarta, Indonesia. Of these, three species, Macrocheles turgoensis n. sp., M. pumilus n. sp. and Glyptholaspis merapiensis n. sp., were described as new to science. The remaining 11 species were Glyptholaspis fimicola (Sellnick, 1931), Neopodocinum spinirostris (Berlese, 1910), M. dispar (Berlese, 1910), M. entetiensis Hartini and Takaku, 2005, M. hallidayi Walter and Krantz, 1986, M. jabarensis Hartini and Takaku, 2003, M. merdarius (Berlese, 1889, M. muscaedomesticae (Scopoli, 1772), M. oigru Walter and Krantz, 1986, M. sukaramiensis Takaku, 2001 and M. sp. aff. glaber (Müller, 1860.

Clean Development Mechanism afforestation often involves the creation of fast growing tree plantations on non-forest lands. To estimate the possible impacts of afforestation on the biodiversity of local species, we compared the diversity of dung beetles collected using baited pitfall traps placed in grasslands, plantations of Acacia mangium, and intact natural forests in East Kalimantan, Indonesia. The species richness in plantations was higher than that on grasslands but lower than that in intact natural forests. Ordination analysis revealed that the structures of beetle assemblages in plantations were intermediate between intact natural forests and grasslands. However, the indicator species for the intact natural forests were never or rarely seen in the plantations. These results suggest that afforestation increases the local native diversity of dung beetles but that plantations are not readily colonized by the indicators of intact natural forests. Conversely, it is suggested that afforestation decreases the abundances of two grassland specialists.

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.

Twenty-two mite species of four genera belonging to the family Macrochelidae were collected from the body surface of dung beetles (Scarabaeidae) in Sungai Wain, East Kalimantan, Indonesia. Three species, Macrocheles dayaci sp. nov., M. riparius sp. nov., and M. wainensis sp. nov., are described as new to science. Another eight species are recorded from Kalimantan for the first time.

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.
