Espèce Pseudodiaptomus sewelli - Planche 2 de figures morphologiquesIssued from : S. Wellershaus in Veröff. Inst. Meeresforsch. Bremerh., 1969, 11 (2). [p.255, Fig.21-22]. As Pseudodiaptomus aurivilli.
Female (from Cochin Backwater, India): 22, P5.
Nota: Exopodal segment 1 of P5 bears only one hair on the outer margin. Ratio cephalothorax: urosome = 1,7; Length of the caudal rami = 7 x breadth.

Male: 21, P5.
Nota: Proportions of the urosomal segments 11 : 20 : 18.5 : 18.5 : 9, caudal rami 23 %. The spine of the outer corner of the 5th thoracic segment is shorter than in the female. As in the female there is a pair of black dots in the anal segment. Spikes are on the whole posterior margin of abdominal 2, 3 and 4, and additional spinules on the ventral aspect of abdominal 2, 3 and 4
