Abstract

Morphological, life history, and distributional data are presented for North American species of the subgenus Allomomonia Cook, 1968. Adults of Stygomomonia (Allomomonia) moodyi Mitchell are redescribed, and deutonymphs and adults of four new species, S. (A.) pacifica, S. (A.) mendocinoensis, S. (A.) mitchelli, and S. (A.) atnarkicola, are described for the first time. Larvae tentatively identified as S. (A.) mitchelli are also described, and host associations of these, and larvae that appear to belong to other species of Stygomomonia, are presented and discussed. New distributional data are presented for all species. A new diagnosis of Allomomonia is proposed, two new species groups, the moodyi and mitchelli groups, are proposed and diagnosed, and a key to adults of North American species of the subgenus is included.

Résumé

Les auteurs présentent des données sur la morphologie, la biologie et la distribution des espèces nord-américaines du sous-genre Allomomonia Cook, 1968. Ils donnent une nouvelle description de l’adulte de Stygomomonia (Allomomonia) moodyi Mitchell, puis décrivent pour la première fois les deutonymphes et les adultes de quatre nouvelles espèces, S. (A.) pacifica, S. (A.) mendocinoensis, S. (A.) mitchelli, et S. (A.) atnarkicola. Ils décrivent en outre des larves provisoirement identifiées comme étant de l’espèce S. (A.) mitchelli et leurs associations d’hôte, et présentent des larves qui semblent appartenir à d’autres espèces du genre Stygomomonia et discutent de celles-ci. Ils fournissent des données sur la distribution de toutes ces espèces. Les deux chercheurs donnent une nouvelle diagnose du sous-genre Allomomonia, proposent la création de deux nouveaux groupes d’espèces, le groupe moodyi et le groupe mitchelli et rédigent des diagnoses de ceux-ci, puis présentent une clé d’identification des adultes des espèces nord-américaines du sous-genre.
