Different from the genus Euaugaptilus by the four-segmented abdomen of the female. Can be distinguished from other species in the genus, P. longerimis, by a larger size, the presence of an outer spine on the second segment of the exopodite of P5, shape of the genital segment, and shape of the mandibles.
Central Arctic Basin, Aleutian Islands, Sea of Japan
Meso-bathypelagic
Female: Abdomen is 3.3 times shorter than the cephalothorax. The genital segment is as long as the length of the next two segments combined plus a third of the anal segment. Caudal rami are 1.5 times longer than the previous segment. The ventral projection on the genital segment is slight, the tip of the projection is abruptly separate. Rostrum consists of 2 thin, very long filaments. A1 longer than the body by 1.5-2 last abdominal segments, the distal segments of A1 sometimes carry large and densely plumose setae. Rami of A2 almost equal in length. The . Mx well developed with 5 setae on the feeding edge. All swimming legs three-segmented. Exopodite of P1 with long outer spines, the last segment carries 2 very long lateral spines and an apical spine.
