Abstract

A new family and superfamily are proposed for Galatheacaris abyssalis, new genus, new species, found in a deep-water sample of the Galathea collections. The new superfamily is characterized by a pectinate sinus between the mandibular processes, an articulated palp on the first and second maxillae, the third maxilliped with 7 segments, the dactyli of the third maxilliped to fifth pereiopods similar and unspecialized, the first and second pereiopods with peculiar microscopic subchela-like structures, all pereiopodal exopods prominent, and small epipods on the third maxilliped to the fifth pereiopod. Relationships to similar caridean superfamilies are considered, and biological remarks are provided.
