ABSTRACT
This paper discusses the newly proposed family Arionoceratidae Dzik 1984 at the familial, generic, and specific levels. An emendation of this family is proposed that clarifies some of this family’s more characteristic features. Evidence for possible sexual dimorphism in Arionoceras submoniliforme (Meneghini 1857) is also discussed.
