Contribution to the knowledge of oribatid mites of Colombia, with description of two new species of Galumna (Acari, Oribatida, Galumnidae)

Abstract

The present study is based on oribatid mite material collected in 1937 in 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 to G. (Galumna) innexa Pérez-Íñigo & Baggio, 1986 by the sculpture of prodorsum, ornamentation of pteromorphs, morphology of bothridial heads, length of rostral and lamellar setae and localization of notogastral lyrifissures im. Galumna (Galumna) naturalisi sp. nov. differs from G. (Galumna) reticulata Hammer, 1958 by the body size, sculpture of prodorsum and the development of lenticulus.
