Species description. Prosome ovoid in dorsal view (Fig. 7: 1), nearly 2.5 times as long as urosome and 2.2 times as long as wide. The first pediger fused to cephalosome, pedigers fourth and fifth fused (Fig. 7: 2).

Spermathecae visible in ventral view but difficult to see in lateral view. Anterior part of genital complex protruding strongly ventrally, forming thick wide fold, covering middle part of double somite (Fig. 7: 4). Antennule of 24 free segments and extending to proximal border of caudal rami (Fig. 7: 2). Mouthparts as in P. tridentatus, with first lobe of maxilliped syncoxa with one seta (Fig. 7: 7); no substantial differences from similar appendages of other species.
