NIWA 76630, Stn. TAN1108/166, North Canterbury, 43.099 –43.095 °S, 173.446– 173.444°E, 79 m, 26 May 2011: 4 M 4.4–5.2 mm, 1 ov. F 4.1 mm, 7F 4.0– 4.8 mm. Donated to MNHN (MNHN-IU-2019-2596). <b>Diagnosis</b> (modified from Schnabel &amp; Ahyong 2019). Rostrum lateral margins convex; subapical spines present. Epigastric region with 4 spines; parahepatic spines on protogastric region absent.Anterior metagastric ridge continuous, not medially interrupted; hepatic spine present. Thoracic sternite 3 anterior margin biconcave, with obtuse median projection. Pleonal tergite 3 with anterior and posterior transverse ridge. Antennular article 1 with 5 distal spines, lateralmost spine always distinct. Antennal article 1 mesial process distally overreaching peduncle and usually reaching second lateral antennular spine; article 2 with lateral spine distinctly larger than mesial spine; article 3 usually unarmed or with minute mesial spine only. Flexor margin of Mxp3 merus with one prominent spine only. P2–4 dactylus extensor margin without upright spines at bases of movable spines. <b>Genetic data.</b> COI and 16S, Table 1. <b>Distribution</b>. New Zealand continental shelf, from the Snares to the Three King Islands and northwards to Norfolk Island, and westward to southern Australia (New South Wales to South Australia), between 15 and 366 m (from Schnabel &amp; Ahyong 2019). <b>Remarks.</b> The species closely resembles <i>P. nui</i> Schnabel &amp; Ahyong, 2019, from New Zealand and Eastern Australia and <i>P. integrus</i> (Benedict, 1902) from Japan to Chesterfield Islands (see the differences under the Remarks of <i>P. integrus</i>).
