The genus Trichosilia Hampson, until now monotypic, is revised to include 10 species, 4 of which are described as new: T. austrina Lafontaine, from Texas; T. woodiana Lafontaine, from northwestern Canada; T. boreana Lafontaine, from northern Canada and Alaska; and T. beringiana Lafontaine and Kononenko, from northwestern Canada, Alaska, and Chukotka, USSR. All species are illustrated and characters to distinguish the species are given. Distribution maps for the species and a phylogenetic analysis of the genus are also included.


Le genre Trichosilia Hampson, considéré monotypique jusqu’à maintenant, a fait l’objet d’une révision pour y inclure 10 espèces, dont 4 sont jugées nouvelles : T. austrina Lafontaine, du Texas; T. woodiana Lafontaine, du nord-ouest canadien; T. boreana Lafontaine, du nord canadien et de l’Alaska; T. beringiana Lafontaine et Kononenko, du nord-ouest canadien, de l’Alaska et de Chukotka (URSS). L’article contient des illustrations de toutes les espèces et donne les caractères distinctifs de chacune. Il comprend aussi des cartes de l’aire de distribution des espèces et une analyse phylogénétique du genre.
