| abstract | The present study is based on oribatid mite material (Oribatida) collected from the Oromia Region in Ethiopia. A new species of the genus Allogalumna (Galumnidae) is described. Allogalumna oromiaensis Ermilov sp.n. differs from A. abrupta (Hammer, 1972) in having lanceolate bothridial setae and in having a complete dorsosejugal suture. Allogalumna oromiaensis also differs from A. bipartita (Aoki et Hu, 1993) in having three pairs of notogastral porose areas and in having a complete dorsosejugal suture. A list of new records of Ethiopian fauna, which includes seven species, is provided. Of these, Malaconothrus aureopunctatus Hammer, 1979 and Tectocepheus minor Berlese, 1903 are recorded for the first time in the Ethiopian region. The other five species, as well as the genera Ululohmannia Mahunka, 1987, Hammerabates Balogh, 1970 and Heterogalumna Balogh, 1960, are recorded for the first time in Ethiopia. |
