Two new species of the subgenus Galumna (Galumna) (Oribatida, Galumnidae) are described from leaf litter of evergreen rain forest in eastern Madagascar. Galumna brevilineatasp. nov. differs from its closest species Galumna (Galumna) anuakensisErmilov, 2019 and Galumna paracalcicolaErmilov & Anichkin 2014 by the length of interlamellar and lamellar setae, the localization of notogastral lyrifissures im, the ornamentation of anogenital region, the morphology of bothridial setae and postanal porose area, and the absence of median pore. Galumna (Galumna) paraarmatiferasp. nov. differs from its closest species Galumna armatiferaMahunka, 1996 by the morphology of bothridial setae and anal plates, and the length of circumpedal carinae. An identification key to species of Galumna (Galumna) of the calcicola-group (species with short lamellar lines) was presented.
