Material examined New Caledonia: (i) BERYX 11, south New Caledonia, stn DW27, 23 ° 379S, 167 ° 419E,

460–470 m, 18 October 1992, 1 ovig. ♀ (MNHN-Na 14885); (ii) BATHUS 3, stn CP832, 23 ° 03.079S, 166 ° 53.709E, 650–669 m, 30 November 1993, 1♀ (MNHN-Na 14941); (iii) HALIPRO 2, Norfolk Ridge , stn BT60, 24 ° 529S, 168 ° 449E , 1133–1280 m, 18 November 1996, 1♀ (MNHN-Na 15880).

Remarks

The specimens fit the original description and illustrations of the species very well, except for the larger body size with the postorbital carapace length 6.1 mm. The smaller body size of the holotype male may be caused by the bopyrid parasites present.

One of the authors (X. Li) checked the ovigerous female (MNHN-Na 12870) reported by Bruce (1996, under the name of P. uniunguiculatus , from Comoro Islands, at a depth of 500 m) and the adult female (MNHN-Na 12042) reported by Bruce (1991a, under the name of P. sp. A, from New Caledonia, at a depth of 825–860 m), during his visit to the museum ( MNHN, Paris, 2004), and found that they are conspecific. Unfortunately, the holotype male was absent then. Anyway, both specimens mostly fit Bruce’s (1990a) description. We are now sure the specimen of Bruce’s (1991a) P. sp. A is identical to the present species. The present records extend the bathymetric range of the species from 460 to 1280 m.

Distribution

Type locality: New Caledonia. Also known from Comoro Islands ( Bruce, 1996) .
