Redescription of Janiralata Pulchra (Hansen, 1916) Oaniridae) from the Kolbeinsey Ridge, North Atlantic and Synonymy with Ianthopsis Pulchra (Acanthaspidiidae) (Crustacea, Isopoda)

Abstract

This paper deals with a poorly known species, Ianthopsis pulchra (Hansen, 1916), found on the Kolbeinsey Ridge, north of Iceland (North Atlantic) during the expedition M21-5 with RV Meteor. The species was thought to be a member of the family Acanthaspidiidae, however, a detailed study, including comparison with the type material of Hansen from the Ingolf expedition and redescription with complete illustration, document that this species belongs to the Janiridae.
