Abstract

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.
