The oribatid mite species Ethiovertex africanus has been recorded for the first time in Ethiopia. A supplementary description of the adult is provided. A description of all juvenile instars is presented; it is the first record of juveniles within Ethiovertex. The larval and nymphal instars are characterized by gastronotum and epimeral and anogenital regions folded; short and spiniform lamellar, interlamellar, exobothridial, gastronotic, epimeral, and anogenital setae (some gastronotic and epimeral setae modified, cylindrical, with needleform apex); short bothridial seta having a globose head; and the absence of setae it’ and it” on leg tarsi I–III in tritonymph.
