Xenocheira
sp.
Xenocheira seurati
Ledoyer, 1984
, 41, fig. 19.
Xenocheira?

Moore, 1988: 712
, figs. 4-7.
Material examined. NCL-210 (3 66, 9 ~~,
2 immature
), NCLÂ 219 (5 ~~).
Remarks. Present material agrees well with that described by Moore from Western Australia and by
Ledoyer (1984)
, from
New Caledonia
.
Xenocheira seurati
was originally described from the Gambier archipelago by Chevreux (1907, 1908).
Moore (1988)
, examined
type
specimens of X.
seurati
,
but in part due to the age of the material, was unable to convince himselfthatAustralian and NewCaledonianmaterial was definitely conspecific with Gambier material. He listed several differences between his material and the
types
and noted the characteristic shape of the pereopod 5 basis, which is very apparent also in our material. Unfortunately
type
material is missing this appendage.
Schellenberg (1938)
recorded a single female specimen, which he attributed to
Xenocheira seurati
,
from
Viti
Levu,
Fiji
. As he provided neither descriptionnorfigures, this record remains enigmatic. For the present, we assign our material to theunnamedtaxonfromAustraliaandNewCaledonia, whilst acknowledging that this taxon may later be shown to be synonymous with X.
seurati
Chevreux.
Lyons & Myers (1990) considered
Xenocheira
to be polyphyletic and transferred X.
fasciata
Haswell to
Bemlos
Shoemaker
and X.
angusticarpa
Ledoyer to
Lemboides
Stebbing. Thus
Xenocheira
now includes 2-3 known species: X.

Habitat.

Acknowledgments. I am grateful to Dr Bertrand Richer de Forges for all his help and hospitality in
New Caledonia
, and to all the ORSTOM staff, especially Jean-Louis Menou, Georges Bargibant, Pascal Hamel and Stephane Bujan for their assistance in sample collection. The work forms part of a larger survey on the amphipods of
New Caledonia
carried out jointly with Drs Jim Lowry and Ichiro Tekeuchi. I thank them both for their comradeship during the field work.
