Abstract

The oribatid mite genus Megeremaeus is redefined, with the addition of information on leg chaetotaxy and immature instars. Three new species are described, Megeremaeus hylaius from northeastern North America, and M. keewatin and M. kootenai from northwestern North America. Descriptions of the former two species are based on adults and immatures, the latter species on adults only. Nymphs of M. montanus Higgins and Woolley are described. A key is given for the six known species in the genus.

Le genre Megeremaeus est redéfini avec l’addition d’information sur la chaetotaxie des pattes et les juvéniles. Trois nouvelles espèces sont proposées, Megeremaeus hylaius de la partie nord-est, et M. keewatin et M. kootenai de la partie nord-ouest de l’Amérique du Nord. Les deux premières espèces sont décrites basées sur les adultes et les juvéniles, la deuxième espèce sur les adultes seulement. Les juvéniles de M. montanus Higgins et Woolley sont décrites. L’ouvrage comprend une clé des six espèces connues. [Traduit par l’auteur]
