Two new species of the genus Galumna (Oribatida, Galumnidae) are described from the Antigua and Aruba Islands (Lesser Antilles). Galumna (Galumna) antiguaensis sp. nov. is morphologically most similar to G.(Galumna) tetraporosa Ermilov, Martens & Tolstikov, 2014, but differs by the smaller body size, presence of three pairs of notogastral porose areas, short interlamellar seta and parallel lamellar and sublamellar lines.Galumna (Neogalumna) harrysmiti sp. nov. is morphologically most similar to G. (Neogalumna) curviporosa(Balakrishnan, 1986), but differs by the minute interlamellar seta, unusual long postanal porose area, band-like porose areas A2 and A3, paraanal position of adanal lyrifissure and the presence of a median pore and longer bothridial seta.
