The present study is based on oribatid mite material (Acari, Oribatida) collected from six localities in Ethiopia during 2013. A list of identified taxa, including 60 species from 45 genera and 30 families, is provided; of these, eight species are recorded in the fauna of this country for the first time, and one species is recorded in the Ethiopian region for the first time. A new species of the genus Wallworkoppia (Oppiidae) is described from litter and fallen leaves in a Juniperus forest; W. tetraciliata Ermilov sp. nov. differs from W. secata (Mahunka, 1999), W. parasensilla (Mahunka, 1999), W. tuberosa (Mahunka, 1988) and W. vibrissa (Mahunka, 1983) by the rounded rostrum (versus tripartite rostrum). An identification key to known species of Wallworkoppia is updated.
