Abstract:

A single carapace and its counterpart of an erymoid lobster collected from the Middle Jurassic Smithers Formation in British Columbia, permits description of a new species, Eryma walkerae. The specimen represents only the fourth species of Eryma described from North America and documents a north polar route of dispersal for erymids into North America.

Une carapace unique d'un homard érymoïde et sa contre-empreinte prélevées dans la Formation de Smithers, du Jurassique moyen, en Colombie-Britannique, rendent possible la description d'une nouvelle espèce, Eryma walkerae Ce spécimen constitue seulement la quatrième espèce d'Eryma d'Amérique du Nord décrite à ce jour et témoigne d'une voie de dispersion vers l'Amérique du Nord qui passe par le pôle Nord pour les érymidés.[Traduit par la Rédaction]
