Abstract

Nothrolohmannia is a genus of oribatid mites that was previously recorded only from Papua New Guinea (PNG), from which two described species are known. Early classifications included this problematic genus in various oribatid mite superfamilies, but it was recently shown to be a sister-genus of Malacoangelia, a member of Hypochthoniidae. We describe the first species of Nothrolohmannia from outside PNG, based on two specimens from Samar Island, Philippines. Unlike the PNG species, it has notogastral porose organs similar to those of Malacoangelia, which solidifies the relationship of the two genera and shows that N. samarensis n. sp. is the most basal known member of Nothrolohmannia. Modifications to the generic diagnosis of Nothrolohmannia are proposed, to accommodate the new species.

Key words: oribatid mite, soil mite, Enarthronota, Malacoangelia, Samar Island
