Abstract
Two new species of the subgenus Galumna (Galumna) (Oribatida, Galumnidae) are described from leaf litter of evergreen rain forest in eastern Madagascar. Galumna brevilineata sp. nov. differs from its closest species Galumna (Galumna) anuakensis Ermilov, 2019 and Galumna paracalcicola Ermilov & 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) paraarmatifera sp. nov. differs from its closest species Galumna armatifera Mahunka, 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.
