Ref.:
Marsh, 1933 (p.35, figs.F,M, Rem.); Wright, 1936 (p.3, figs.F,M); 1937 (p.160); Dussart & Defaye, 1983 (p.30); Dussart, 1984 a (p.27, fig.M); Grindley, 1984 (p.221, Rem.); Walter, 1986 (p.131, 140); 1986 a (p.502, fig.1: zoogeogr.); 1987 (p.366); Defaye & Dussart, 1988 (p.112, figs.F,M, Rem.); Walter, 1989 (p.610, figs.F,M; Rem.)
Species Pseudodiaptomus gracilis - Plate 1 of morphological figuresissued from : T.C. Walter in Bull. Mar. Sc., 1989, 45 (3). [p.611, Fig.11].
Female: A, habitus (dorsal); B, idem (lateral left side); C, Head (ventral); D, caudal rami showing naked lateral spine-like seta; E, P5 (anterior view).

Male: F, habitus (dorsal); G, idem (lateral right side); H, P5 (posterior view); I, idem (anterior view).


Species Pseudodiaptomus gracilis - Plate 2 of morphological figuresissued from : S. Wright in Ann. Acad. Brasileira Sci., 1936, VIII (1). [Pl.1, Figs.1-8].
Female: 3, urosome (dorsal); 6, forehead (ventral; showing bifid rostrum, base of left A1 and lateral spine); 7, genital segment with spermatophore (lateral, right side); 8, right P5.

Male: 1, P5; 2, left P5 ( from left side); 4, right A1 (segments 9 to 13, showing spines only); 5, right P5 (1st exopodite segment, from right side).


Species Pseudodiaptomus gracilis - Plate 3 of morphological figuresissued from : B.H. Dussart in Hydrobiologia, 1984, 113. [p.27, Fig.2].
Male (from Venezuela).


Species Pseudodiaptomus gracilis - Plate 4 of morphological figuresIssued from : C.D. Marsh in Proc. U.S. natn. Mus., 1933, 82 (18) (2959). [Pl. 18, figs.4-6].
Female: 4, P5.
Nota: Wright stated that the head bears a pointed process on either side. These spines were not seen in the material strudied by the author.

Male: 5, P5; 6, urosome (dorsal).
Nota: left exopod 3-segmented. Though wright considered the left exopod 2-segmented, his figure apparently shows 3 degments/
