Fig. 8A
). (From colour slide). Uniform deep red, except for narrow median dorsal stripe, deepest yellow on rostrum, posteriorly to fourth abdominal tergite. Specimen (2) lacked the dorsal yellow stripe and had the ambulatory propods transparent.

Remarks
. The specimens agree fully with the original description. The ovigerous female (2), CL 3.2, has a bluntly rounded nonsetose preterminal distal dorsal tooth and a very small distal ventral rostral tooth only. The single male in lot (1), CL
1.6 mm
, has a well developed rostral dentition: the dentition is feebly developed in all females, as in the
type
material.
The present specimens were collected from slightly shallower depths than the earlier specimens, which were mainly from over
400 m
.
The
type
specimens were collected from
503 m
.
Distribution
. Recorded only from the region of
New Caledonia
, the Loyalty Islands and the northern Tasman Sea.
