A revision of the North American species of Brachylomia (Lepidoptera: Noctuidae: Xyleninae) with descriptions of four new species

  • James T. Troubridge (a1) and J. Donald Lafontaine (a1)


The North American species of Brachylomia Hampson, 1906 are revised and four new species (B. cascadiasp. nov., B. obscurifasciasp. nov., B. pallidasp. nov., and B. sierrasp. nov.) are described. The monotypic genus Lomilysis Franclemont, 1937 is synonymized with Brachylomia. Epunda onychina Guenée, 1852, which is currently placed in Brachylomia, is reclassified as a senior synonym of Egira alternans (Walker, [1857]), but Epunda onychina, not being associated with any known species in more than 150 years, is treated as a nomen oblitum, so Egira alternans is a nomen protectum under provisions of Article 23.9.2 of the International Code of Zoological Nomenclature. Adults and genitalia of Nearctic species of Brachylomia are figured.

Nous révisons les espèces nord-américaines de Brachylomia Hampson, 1906 et nous décrivons quatre nouvelles espèces (B. cascadiasp. nov., B. obscurifasciasp. nov., B. pallidasp. nov. et B. sierrasp. nov.). Le genre monotypique Lomilysis Franclemont, 1937 devient synonyme de Brachylomia. Nous plaçons Epunda onychina Guenée, 1852, actuellement inclus dans Brachylomia, comme synonyme plus ancien d'Egira alternans (Walker, [1857]); cependant parce qu'Epunda onychina n'a été associé à aucune espèce connue depuis plus de 150 ans, nous le traitons comme nomen oblitum; ainsi, Egira alternans devient un nomen protectum selon les provisions de l'article 23.9.2 du Code International de Nomenclature Zoologique. Nous donnons des illustrations des adultes et des organes génitaux des espèces néarctiques de Brachylomia.
