Oribatid Mites from Several Mires in Northern Japan
II. Three Species of the Genus Hydrozetes (Acari: Oribatida) including Two New Species

Abstract

Two new species of Hydrozetes are described from several Sphagnum mires in Japan: Hydrozetes japonicus sp. n. and H. harundinosus sp. n. Local variability and certain ecological characters are surveyed in H. japonicus, a common species in the Sphagnum mires of North Japan. H. lemnae (Coggi, 1897) was collected for the first time from Japan. The Japanese species is redescribed in this paper.
