Type material. Zeidler (1995) established that Fabricius (1775) based his original description of this species solely on drawings made by Sydney Parkinson, labelled “ Onidium gibbosum ”, now held by the NHM, London. An examination of these drawings suggest that this is most likely a species of Lycaea, but that the drawings, and description, lack sufficient detail to make a specific determination. The type locality is the Atlantic Ocean, near Portugal, inside a salp (Dagysas sp.).
