Abstract

The oribatid mite genus Zachvatkinibates, found in both littoral and forest litter habitats in North America and the Soviet Union, is redefined. Its systematic relationship to other genera in the Mycobatidae is discussed. A new species, Z. tetrasklerosis, is proposed, and Z. maritimus Shaldybina, 1973, is redescribed. Immatures of both species are described; none was previously known for the genus. Sexual dimorphism is displayed in the notogastral porose areas of adults of Z. maritimus, but not of Z. tetrasklerosis.

Résumé

Le genre Zachvatkinibates trouvé dans les habitats littoraux et litières forestières du continent Nord-Américain et de l’Union Soviétique, est redéfini, et sa relation systématique aux autres genres de Mycobatidae est discutée. Une nouvelle espèce Z. tetrasklerosis est proposée, et Z. maritimus Shaldybina 1973 est décrite à nouveau. Les juvéniles de ces deux espèces sont décrites, aucune n’étant antérieurement connue pour ce genre. Le dimorphisme sexuel est exposé dans les régions poreuse du notogaster des adultes de Z. maritimus, mais non chez Z. tetrasklerosis.
