Remarks.
As
reported by
Baba & Poore (2002)
for southeastern Australian material, the two spines at the anterolateral angle of the carapace in the present specimens are subequal. One male (26.0 mm pcl,
Fig. 2
C, D) is atypical in lacking the rostrum entirely and the ovigerous female bears 1 or 2 minute spines behind the anterolateral spines. The specimens otherwise agree with the recent accounts from the area (
Baba & Poore 2002
;
Macpherson 2007
). Notably, the posterior margin of the mesogastric spine in the present series is straight as in New Caledonian specimens rather than slightly convex as in West African material (
Macpherson 2007
).
Distribution.
Atlantic and Southern oceans, Indian Ocean, western and eastern Pacific. The Indo-West Pacific range includes
Zanzibar
, the Arabian Sea,
Indonesia
,
Japan
,
Australia
,
New Caledonia
, and now

;
