Two new species of oribatid mites (Acari: Oribatida) are proposed, each based on single specimens included in Baltic amber. Callohmannia schusteri n. sp. and Hermannia sellnicki n. sp. represent the first pre Quaternary fossils of their respective genera. The taxonomic positions of six other oribatid mite genera proposed by Max Sellnick on the basis of Baltic amber inclusions, which are now lost, are reconsidered due to changes in family concepts since their original proposal. Scutoribates, formerly in Carabodidae, is a junior synonym of Eremaeozetes Berlese (n. syn.) in the Eremaeozetidae. Embolacarus is reassigned to Collohmanniidae. Tectocymba and Gradidorsum are tentatively retained in Cymbaeremaeidae and Eremaeidae, respectively. Strieremaeus and Plategeocranus are removed from their current families, Eremaeidae and Carabodidae respectively, but cannot be reassigned based only on original descriptions.
