Three new species were described for the first time in the present thesis (Macrocheles lumbiensis, M. lorensis, and Neopodocinum murungensis), three species were already described and published by author during the study (M. dayaci, M. riparius, and M. wainensis), 16 species have already known previously, and 13 species recorded from Kalimantan for the first time. A key to 35 species (female) of the family in Kalimantan was provided. Based on morphological characters, especially dorsal and sternal characters, three species of the genus Holostaspella were classified into 3 species groups (bifoliata, mirabilis, and sculpta species group). Nineteen species of the genus Macrocheles maybe classified to the four species groups (glaber species group, muscaedomesticae group, subbadius group, and krantzi group) and seven species complexes. Five complexes are belonging to glaber group, i.e., glaber complex (including Macrocheles sp. aff. glaber (Müller, 1860), M. oigru Walter and Krantz, 1986, and M. dayaci Dwibadra and Takaku, 2014), kraepelini complex (including M. kraepelini (Berlese, 1905) and M. hallidayi Walter and Krantz, 1986), scutatus complex (M. dispar (Berlese, 1910), M. entetiensis Hartini and Takaku, 2005, M. jabarensis Hartini and Takaku, 2003, M. nidus Hartini and Takaku, 2013, and M. persimilis Hartini, Dwibadra and Takaku, 2007), pumilus complex (including M. pumilus Hartini, Dwibadra and Takaku, 2009 and M. riparius Dwibadra and Takaku, 2014), baramensis complex (including M. baramensis, M. kalimantanensis, and M. lumbiensis). One species complex, merdarius complex, is included in subbadius group. The krantzi species group and pumilus and baramensis 1 complexes belonging to glaber species group were established and their diagnoses were defined here. Macrochelids of Kalimantan (including Malaysian part) were found to be phoretic on 9 genera of scarab beetles Aphodius, Caccobius, Catharsius, Copris, Onitis, Oniticellus, Onthophagus, Paragymnopleurus, and Sisyphus (Coleoptera: Scarabaeidae), one genus of geotrupid beetle Bolbochromus (Geotrupidae), and one genus of scavenger scarabaeid beetle Phaeocroops (Hybosoridae). Twenty two species of mites were collected from the genus Catharsius, 19 spp. from Onthophagus and 13 spp. from Paragymnopleurus. These results suggest that larger sized genus or diversified genus of beetle tend to harbor large number of species of macrochelid mites. Most of macrochelid mites were associated with several genera of beetles (e.g., Macrocheles hallidayi were found on 5 genera of beetles, M. kalimantanensis on 7 genera of beetles), and macrochelids associated with dung beetles in Kalimantan did not show preference to particular species of dung beetles. In this study, five groups of geographical region based
