Sars, 1902 (1903) (p.102: Rem.); Tollinger, 1911 (p.212, fig.16); Willey, 1920 a (p.11, figs.F); Gurney, 1931 a (p.185); Shih & al., 1971 (p.208); Heron & Damkaer, 1976 (p.129, Table 2); Kos, 1977 a (p.20); 1991 (p.112-116, figs. 38-39); 2016 (p.74, figs. F, M, Rem.)
Species Eurytemora gracilis - Plate 1 of morphological figuresIssued from : A. Willey in Rep. Can. Arct. Exp. 1913-18, 1920, VII, Part K. [p.12K, Figs.3, 4].
Female (from 68°41'N, 165°10'W; damaged): 3, urosome (dorsal); 4, P5.

Nota: Relative lengths of anal segment and caudal rami 9 : 15.
In P5, the distal segment was lost; the unguiform process of the proximal segment (endopodite 1) projects nearly horizontally inwards, abruptly narrowing to a distal acuminate portion which is ciliated on the inner edge.
Genital segment with lateral convexities separated by a constriction.
