First reports of Galumnellidae (Acari, Oribatida) from the Philippines, with description of Galumnella junichiaokii sp. n.

Abstract

Oribatid mites (Acari, Oribatida) of the family Galumnellidae are recorded from the Philippines for the first time, represented by Porogalumnella reducta Mahunka, 1995 (previously known from only Borneo) and a new species of Galumnella. Galumnella junichiaokii sp. n., is described and illustrated on the basis of adult specimens. This species is morphologically similar to G. nipponica Suzuki et Aoki, 1970, from Japan, but differs by its smaller body size, the presence of a dorsal longitudinal ridge and lateral tooth-like projections on the prodorsum, a large anterior tectum on epimere I, and lamellar and sublamellar lines that diverge distally.
