Abdominal segments and caudal rami in the proportional lengths 40 : 14 : 14 : 18 : 14 = 100. Genital segment asymmetrical, the right lateral margin is much produced; genital area furnished with 2 irregular lamellous plates; the distal ventral margin of the segment has a triangular process on the left side. Caudal rami 1.5 times as long as wide. A1 extends to the posterior margin of the 3rd thoracic segment. Male: e, right P5; f, left P5. Nota: Cephalothorax 1.52 mm; abdomen 0.77 mm. The last thoracic segment slightly asymmetrical; the lateral corner triangularly produced with a small process on the distal margin (in some specimens the lateral margin has 2 small processes). In P5: distal segment of the left leg elongated and curved. Right leg with a very small process on the inner proximal margin of the 3rd segment; the distal segment long and spoon-shaped.

[p.129, Fig.88]. Male (from same locality than female): A, habitus (dorsal); B, left A1; C, A2; D, mandibular palp; E, Mx1; F, Mx2; G, Mxp; H, P1; I, P2; J, P3; K, P4; L, right P5; M, left P5. Female characteristics: Posterior borders of pediger segments 4+5 almost equal. - Genital segment quite large, asymmetrical with a swelling on the right. - Caudal rami divergent. - A1 much shorter than body. - P5 narrow with oblique articulations between exopod segments. Male characteristics: Caudal rami divergent. - P5 left endopod large and triangular. Nota: It seems that P. helgae also has an extension of the right male P5 exopod segment 2 although neither Farran (1905) nor Sars (1925) figures this character. Also the conspicuous constriction dividing the distal part of male left P5 exopod segment 2 from the rest of the limb is not figured by Farran (1905).
