From an examination of the original material of G. O. Sars and new material from Björnehodebukta, Oslofjord, Psammis longisetosa Sars is redescribed, noting in particular the presence of 2 inner setae on P2 endopod 2 and 1 inner seta on P4 exopod 1. A new species is described from the Celtic Sea, Paradanielssenia biclavata , characterized by the presence of club‐shaped appendages on the mouthparts and differing from P. kunzi Soyer in mouthpart structure and limb setation. Specimens from the Gulf of Mexico have been assigned to a new subspecies, Thompsonula hyaenae elongata , after careful comparison with specimens of the nominate T. hyaenae (I. C. Thompson) from Europe and South Carolina.
