| abstract | The present study is based on oribatid mite material (Acari, Oribatida) collected from the vicinities of Dhati-Walal National Park in Ethiopia in 2017. A list of identified taxa, including 56 species from 46 genera and 25 families is provided; of these, 10 species and 4 genera are recorded for the first time in the fauna of this country. A new species of the genus Sadocepheus (Compactozetidae) is described; Sadocepheus dhatiwalalensis Ermilov sp. nov. differs from Sadocepheus subniger (Ewing, 1917) by the larger body size, truncate lamellar cusps with lateral and medial points and brush-shaped, erect bothridial setae. The species Scheloribates leleupi Balogh, 1959 (Scheloribatidae) is redescribed and illustrated in detail, based on specimens from Ethiopia; the main morphological traits for this species are summarized. Morphological additions to the description of Galumna incisa Mahunka, 1982 (Galumnidae) are presented. |
