A new oribatid mite subgenus, Perscheloribates (Ecuadoribates) subgen. nov., and three new species, Perscheloribates (Ecuadoribates) pentasacculus sp. nov., Fissurobates neotropicus sp. nov. and Mucrobates microsetosus sp. nov., of the family Scheloribatidae are described from Ecuador. The new subgenus differs from Perscheloribates (Perscheloribates) by the number of notogastral sacculi and number of genital setae. Fissurobates and Mucrobates are recorded for the first time in Ecuador. The morphology of gnathosoma and legs are presented for the first time for any member of Fissurobates and Mucrobates.
