A new oribatid mite species, Perscheloribates paratzitzikamaensis n. sp., is described from Ecuador. This species is morphologically similar to Perscheloribates tzitzikamaensis (Pletzen, 1965) from South Africa, however, it differs from the latter by the smaller body size, longer notogastral setae p1, the absence of a translamellar line and prolamellar lines represented only by short basal part. The supplementary descriptions of Scheloribates elegans Hammer, 1958 and Monoschelobates parvus Balogh and Mahunka, 1969 are presented on the basis of Ecuadorian specimens.
