Two new species of oribatid mites, Suctobelbella (Ussuribata) phylliformis sp. n. (Suctobelbidae) and Neoribates (Neoribates) paratuberculatus sp. n. (Parakalummidae), are described from ferralitic soil of polydominant forest in Dong Nai Culture and Nature Reserve, southern Vietnam. Suctobelbella (Ussuribata) phylliformis sp. n. is similar morphologically to S. (U.) separata Mahunka, 2001, however, the new species differs from the latter by the number of genital and adanal setae, the morphology of the knob-like tubercle and the number of lateral prodorsal teeth. Neoribates (Neoribates) paratuberculatus sp. n. is similar morphologically to N. (N.) tuberculatus Willmann, 1956, however, the new species differs from the latter by the smaller body size, density of tubercles on pteromorphs and the morphology of bothridial setae. The validity of Suctobelbella (Ussuribata) is discussed; an identification key to all species of this subgenus is given.
