ABSTRACT: Pergalumna tsavoensis Mahunka, 1986 and P. bifissurata Hammer, 1972 are redescribed on the basis of specimens from Zambia and Brazil, respectively. The dentate anterior tectum of epimere I in P. tsavoensis and microgranular body surface, rounded rostrum and absence of postanal porose area in P. bifissurata should be considered in any future identification of these species.

KEY WORDS: oribatid mites, Galumnidae, Pergalumna tsavoensis, P. bifissurata, supplementary description, Zambia, Brazil.
