ABSTRACT: The oribatid mite genus Zetorchella (Acari: Oribatida: Caloppiidae) comprises 16 species. We describe Zetorchella nortoni sp. n., collected in mosses on trees from Ethiopia. The new species is most similar to Zetorchella orbiculata Wen, Zhao, 1994 (Asia, China), but differs from this species by the length of the body, the morphology of sensilli, the length of interlamellar setae, and the morphology of notogastral setae p2, and p3. Among African species the new species is most similar to Zetorchella basylewskyi (Balogh, 1958), but differs from this species by body size, the length of interlamellar setae and setae c, and the morphology of notogastral setae.
KEY WORDS: oribatid mite, new species, Caloppiidae, Zetorchella nortoni sp. n., Ethiopia.
