Oribatid mite fossils from pre-Quaternary sediments in Slovenian caves III. Two new species of Dissorhina (Oppiidae) from the Pliocene

摘要

Two new fossil species of the extant genus Dissorhina Hull, 1916 (Oribatida, Oppiidae) are described from Pliocene clastic sediments in Trhlovca cave of the Slovenian Classical Karst (Kras): Dissorhina paleokrasica n. sp. and Dissorhina nuda n. sp.. Diagnoses of both new species are given on the basis of detailed study of few damaged adult individuals obtained by sieving. Relationships to recent species of the genus and the possible importance of the Balkan Peninsula for the speciation of Dissorhina are discussed.
