Planche 1 issued from : S. Chullarson, F.D. Ferrari & H.-U Dahms in Helgol. Mar. Res., 2010, 64; [p.51, Fig.14, A-D].
Male (from Shedd Aquarium Chicago): A: P5 (potopod and endopods, anterior view); B, right exopod of P5 (anterior view); C, proximal segment of right exopod of P5 (posterior view); D, left exopod of P5 (anterior view).

Nota: This species is similar to P. schminkei, but the distal attenuation of articulating segment 15 on right A1 of males reaches beyond segment 16 as it does forP. schminkei. The intercoxal plate of male P5 has a simple, ventral lobe (fig. A), and the distal segment of the right exopod is thick, relative to its length (fig.B, C). The proximal lobe of the distal segment of left exopod is not simply quadrate, and the distal part of the limb is broader (fig.D).

Planche 2 issued from : S. Chullarson, F.D. Ferrari & H.-U Dahms in Helgol. Mar. Res., 2010, 64; [p.51, Fig.14, E-G].
Male: E, left exopod of P2 (middle segment and distal complex, anterior view); F, right exopod of P2 (middle segment and distal complex, anterior view); G, right exopod of P2 (lateral seta of middle segment and proximo- and distolateral seta of distal complex, lateral view).

Another difference with P. schminckei: the lateral seta on middle exopodal segment of the right P2 of males is irregularly swollen (fig. E,F); the proximal seta on distal segment is curved posteriorly, and the lateral margin between tje proximal and distal lateral seta is swollen (fig.E,G)
