Material examined. West Norfolk Ridge: NMNZ, 1 male (31.2 mm), 1 ovigerous female (31.3+ mm; ovum diameter 2.8 mm), 35°35.83’S, 169°33.43’E, 1760–1786 m, TAN0308/167 #016, 5 Jun 2003; NIWA 28060, 2 males (26.0[pcl.]– 31.5 mm), 35°35.83’S, 169°33.43’E, 1760–1786 m, TAN0308/167 #016, 5 Jun 2003.

Colour in life. Orange overall.

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 View FIGURE 2. A, B 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 New Zealand; 1584–3294 m ( Ahyong & Poore 2004; Macpherson 2007).
