Pseudodiaptomus cornutus  Nicholls, 1944   (F,M)
Syn.: no Pseudodiaptomus cornutus : Tanaka,1966 (p.40,figs.F)
Ref.:
Nicholls, 1944 (p.8, figs.F,M); Hirakawa, 1983 (p.68, Rem.); Walter, 1986 (p.133, 155, fig. F,M); 1986 a (p.503); 1987 (p.368, 376, figs.F,M, Rem.); Bradford-Grieve,1999 b (p.152, figs.F,M, fig.181)
Species Pseudodiaptomus cornutus - Plate 1 of morphological figuresissued from : T.C. Walter in J. Plankton Res., 1986, 8 (1). [p.154, Fig.11, K-L].
Female: L, P5 (posterior view).

Male: K, P5 (posterior view).


Species Pseudodiaptomus cornutus - Plate 2 of morphological figuresissued from : T.C. Walter in Aust. J. Mar. Fresfw. Res., 1987, 38. [p.377, Fig.6].
Female: A, habitus (dorsal); B, prosome (lateral right side); C, urosome (lateral right side); D, P5 (posterior view).

Male: E, habitus (dorsal); F, portion of prosome and urosome (lateral right side); G, P5 (posterior view); H, idem (anterior view).


Species Pseudodiaptomus cornutus - Plate 3 of morphological figuresissued from : K. Hirakawa in Bull. Plankton Soc. Japan, 1983, 30 (1). [p.68, Table 1].
Female & Female: Comparison of the morphological characters in P. nihonkaensis and P. cornutus Nicholls, 1944.
Nota: The original description by Nicholls (1944) is incomplete in some details. After examination of the type specimens of P. cornutus, I propose to correct as follows:
Female: 1 - The inner distal corner of the 1st exopod segment of P5 is not triangular form, but round; 2- The genital somite bears several patches of strong spines on the right lateral side.
Male: The outer lamelliform plate in the right endopod of P5 bears spinules on its distal margin.
