An annotated checklist of oribatid mite taxa from two forest plantations of Dong Nai Biosphere Reserve (Southern Vietnam) is presented. It includes 55 species, 39 genera and 23 families. Otocepheus spatulatus,Yoshiobodes aokii, Acrogalumna bipartita and the genera Yoshiobodes, Suctobelbata are first records from Vietnam. Suctobelbata is recorded for the first time from the Oriental region. Suctobelbata bituberculata sp. nov. (Suctobelbidae) is described from litter. The new species is most morphologically similar to Suctobelbata truncicola (Forsslund, 1941) from the Palearctic region, but it is clearly distinguishable from the latter by the rectangular tectopedial fields, setiform rostral setae and the prodorsal tubercle represented by a transverse line.
