Two new species of oribatid mites of the genus Oribatella (Oribatida, Oribatellidae)—O. paradechambrieri sp. nov. and O. parastrinatii sp. nov.—are described, based on adults collected from rainforest litter in Guatemala. Oribatella paradechambrieri sp. nov. is similar to O. dechambrieri but differs by the smaller body size, the length of the teeth of the lamellae, the relative length of the free distal and fixed mediobasal parts of the lamella, the size of the trapezoid region in basal part of the prodorsum, and the length of the interlamellar seta. Oribatella parastrinatii sp. nov. is similar to O. strinatii but differs by the smaller body size, the morphology of the rostrum, the morphology of the tutorial cusp, the presence of large dense foveolae in the centrodorsal part of the notogaster and between the genital and anal apertures, and dense short transverse ridges on the medioposterior part of the notogaster, and the number of genital setae. Oribatella dechambrieri is the first record of the species for Guatemala. The belonging of O. paradechambrieri to the genus Fenestrobates is discussed.
