This work includes taxonomic and faunistic data on oribatid mites (Oribatida) of the superfamily Galumnoidea which were collected in Malaysia. Two new species are described. Galumna perakensissp. nov. differs from Galumna alata, G. cavernalis and G. tokyoensis by the costate prodorsum and reticulate pteromorphs. Pergalumna titiwangsaensissp. nov. differs from Pergalumna paraindistincta by the pointed rostrum and relatively long anal setae. Five species (Allogalumna dilatata, A. indonesiensis, Carinogalumna philippinensis, Galumna granalata, Pergalumna paraindistincta), one subgenus (Flagellozetes (Cosmogalumna)) and one genus (Carinogalumna) are recorded in Malaysia for the first time.
