Abstract

Six species of oribatid mites (Acari: Ceratozetidae) in six genera were recorded from a variety of arboreal habitats in western Canada, including the canopy of temperate rainforest, montane forest, and the leaves of shrubs. Four of these species are new to science and are described: Sphaerozetes winchesterisp.nov., on the basis of adults; and Dentizetes ledensissp.nov., Melanozetes crossleyisp.nov., and Neogymnobates marilynaesp.nov., on the basis of adults and immatures. Jugatala tuberosa Ewing is redescribed from both adults and immatures, a new observation being that adults have seven pairs of notogastral porose areas. The placement of the genus Jugatala Ewing in Ceratozetidae is confirmed. Latilamellobates baloghi (Mahunka) is newly recorded from North America, and the taxonomy of the genus is discussed. The major differences among these six species are presented in tabular format.

Résumé

Six espèces d’oribates (Acari : Ceratozetidae) appartenant à six genres ont été recensées dans une variété d’habitats arboricoles de l’ouest du Canada, dont la canopée de fôrets tempérées pluvieuses, de fôrets montagneuses, et dans les feuilles d’arbustes. Quatre de ces espèces n’ont jamais été décrites. La description de Sphaerozetes winchesterisp.nov. est basée sur les adultes, alors que celles de Dentizetes ledensissp.nov., Melanozetes crossleyisp.nov., et Neogymnobates marilynaesp.nov., sont basées sur les adultes et juvéniles. La redescription de Jugatala tuberosa Ewing est basée sur les adultes et juvéniles, et les adultes ont sept paires d’aires poreuses à leur notogaster. Le placement de Jugatala Ewing parmis les Ceratozetidae est confirmé. Latilamellobates baloghi (Mahunka) est nouvellement découvert en Amérique du Nord, et la taxonomie de ce genre est discutée. On trouvera ici un tableau contenant les differences majeures entre ces six espèces de Ceratozetidae.
