Two new oribatid mite species of Oppiidae, Gittella ecuadoriensis sp. nov. and Lasiobelba (Antennoppia) chistyakovi sp. nov., are described from Ecuador. Gittella and Lasiobelba are recorded for the first time from Ecuador. Gittella ecuadoriensis sp. nov. differs from all species of the genus by the selective characters (long, setiform and smooth notogastral setae, granulate body surface, sensilli with long cilia, absence of muscle sigilla in interbothridial and epimeral regions). Lasiobelba (Antennoppia) chistyakovi sp. nov. differs from all species of the subgenus by the setiform sensilli with long cilia and localization of lamellar setae nearer to interlamellar setae, than rostral setae. An identification key to all known species of Gittella is presented.
