| Abstract |
The study of many samples collected by MUSORSTOM cruises, deposited in the Muséum national d'Histoire naturelle, as well as the reexamination of types and published specimens reveal that Pasiphaea sivado (Risso, 1816) and the related species, P. propinqua de Man, 1916, P. japónica Omori, 1976, P. marisrubri Iwasaki, 1989 and P. nudipeda Burukovsky, 1993, belong to one group. All are characterized by a terminal spine on the sixth abdominal somite and a branchial reduction. However, P. nudipeda is entirely devoid of arthrobranchia, has unarmed first pereiopods and three pairs of spines on the posterior margin of telson and has to be separated; a new genus Alainopasiphaea is proposed for it. The other species mentioned above, except P. marisrubri, bear three arthrobranchiae from the fourth to sixth thoracic somites. P. marisrubri and five new species found in the MUSORSTOM material and belonging in this group have four pleurobranchiae from the fourth to seventh thoracic somites. On the other hand, P. propinqua, P. japónica and P. sivado have one more, but rudimentary, pleurobranchia on the eighth somite. A key for all these species is provided. |
