Cryptoteuthis brevibracchiata: a new species and genus of cirrate octopod (Octopoda: Cirrata)

A new species and genus of cirrate octopod, Cryptoteuthis brevibracchiata, is described from a single specimen captured at 2274-2300 m in the Porcupine Seabight, northeastern Atlantic. The species possesses characteristics of both Opisthoteuthis and Grimpoteuthis, but is sufficiently distinct from both to warrant placement in a new genus, within the family Grimpoteuthidae.
