The oribatid mite genus Macrogena (Acari, Oribatida, Ceratozetidae), with description of two new species from New Zealand

Abstract

Two new species of oribatid mites of the genus Macrogena (Oribatida, Ceratozetidae) are described from alpine soils of the South Island of New Zealand. Macrogena brevisensilla sp. n. and M. abbreviata sp. n. differ from all species of this genus by the tridactylous legs and by the comparatively short interlamellar setae, respectively. New generic diagnosis and an identification key to the known species of Macrogena are provided.
