Abstract

Adults of Cyclothyas siskiyouensis n. sp., the first species of the genus reported from the Western Hemisphere, are described from female specimens collected from a small stream in Oregon, U.S.A. Members of this species differ from those of previously described species in having 3, rather than numerous, pairs of genital acetabula along outer edges of the genital flaps. A revised diagnosis of the genus Cyclothyas is presented.

Résumé

L'auteur décrit des adultes femelles de Cyclothyas siskiyouensis, nouvelle espèce, d'un petit ruisseau en Oregon, États-Unis. C'est la première mention de ce genre dans l'Hémisphère de l'Ouest. Les membres de cette espèce diffèrent de ceux des autres espèces déjà décrites par la présence de trois, plutôt que plusieurs, paires de verrues génitales sur les bords latéraux des valves génitales. Un nouveau diagnostic du genre Cyclothyas est présenté.
