The present study is based on oribatid mite material collected in 1937 from Colombia. A list of identified taxa, including 13 species from 11 genera and 10 families, is presented; of these, two species of the genus Galumna are new to science, 10 species, 10 genera and eight families are recorded in this country for the first time. Galumna (Galumna) colombiana sp. nov. differs from G. (Galumna) innexa Pérez-Íñigo & Baggio, 1986 by the sculpture of the prodorsum, ornamentation of the pteromorphs, morphology of the bothridial heads, length of the rostral and lamellar setae, and the localization of the notogastral lyrifissures im. Galumna (Galumna) naturalisi sp. nov. differs from G. (Galumna) reticulata Hammer, 1958 by the body size, sculpture of the prodorsum and the development of a lenticulus.
