Mites of the superfamily Rhodacaroidea (Acari: Mesostigmata) from Colombia, with a key for the world species of Desectophis Karg (Ologamasidae)

Three species of Rhodacaroidea are reported from soil in Colombia. Desectophis anthuriumsetis n. sp. (Ologamasidae) and Multidentorhodacarus colombianus n. sp. (Rhodacaridae) are described from newly-collected material. Multidentorhodacarus triramulus (Karg, 1998) is redescribed from the holotype and adult females collected in this study. A key for the separation of females of the five recognisable world species of Desectophis Karg is provided.
