Abstract

Two new genera and species of arionid slug, Securicauda hermani n. gen. et n. sp. and Carinacauda stormi n. gen. et n. sp., are described from the United States in northern Idaho and westem Oregon, respectively. This taxonomic decision is based on anatomical comparisons to the ten genera of Arionidae native to northwestem North America. Securicauda lacks an atrium and atrial accessory stmctures and the epiphallus is almost entirely buried in the penis; Carinacauda has an atrium, a pair of atrial accessory stmctures, and a long epiphallus that is not embedded in the penis.
