Abstract

Adults of Cyclomomonia andrewi gen.nov., sp.nov. are described from interstitial habitats in small, cascading streams in western North America. The genus Cyclomomonia and the subfamily Cyclomomoniinae are proposed and diagnosed, based primarily on the distinctive, complex structure of the dorsal and ventral shields and the genital field. Possible relationships between Cyclomomonia and other Momoniidae are discussed, and a new key to the world genera and subgenera of the family is presented.

Résumé

L’ouvrage décrit des adultes de Cyclomomonia andrewi, nouveau genre et nouvelle espèce, prélevés d’habitats interstitiels dans de petits ruisseaux en cascades de l’ouest de l’Amérique du Nord. Le genre Cyclomomonia et la sous-fanùlle des Cyclomomoniinées sont proposés et diagnostiqués, essentiellement d’après la structure typiquement complexe des boucliers dorsal et ventral et des genitalia. L’auteur discute des rapports possibles entre Cyclomomonia et d’autres Momoniidées et présente une nouvelle clef d’identification des genres et sous-genres mondiaux de la famille.
