Colour in life. Overall red.

Remarks. The present specimens of P. e n t h r i x agree well with recent accounts ( Galil 2000; Ahyong & Brown 2002). Lateral carapace spination is 8–10: 3–4: 12–17, and the antrorse tooth on the abdominal tergite 5 is pointed in adult females, blunt in adult males. The spination of the anterior carapace margin flanking the rostral spines varies allometrically. The inner orbital spine and a second similar spine are always present, but the additional smaller marginal spines vary in length and number according to body size. Nevertheless, a row of small spines is always present in addition to the two larger spines, distinguishing P. e n t h r i x from the northwestern Pacific species, P. amemiyai Yokoya, 1933 , which bears only two spines on either side of the rostral spines.

Distribution. Fiji to New Zealand, and Australia; 229–1152 m ( Ahyong & Brown 2002).
