Centropages elegans  Giesbrecht, 1895   (F,M)
Ref.:
Giesbrecht, 1895 c (p.256, pl.4, figs.1-2: M); Giesbrecht & Schmeil, 1898 (p.57); Brodsky, 1950 (1967) (p.319, figs.M); Vervoort, 1964 b (p.309); Park, 1968 (p.557, Redescr. F,M, figs.F,M); Vidal, 1968 (p.36, figs.F,M); Roe, 1975 (p.344, Rem.); Bradford-Grieve,1999 b (p.137, figs.F,M, Rem.)
Species Centropages elegans - Plate 1 of morphological figuresissued from : Bradford-Grieve J.M. in The Marine Fauna of New Zealand: Pelagic Calanoid Copepoda. National Institute of Water and Atmospheric Research (NIWA). NIWA Biodiversity Memoir, 111, 1999. [p.138, Fig.95].
Female (29°03.5'S, 168°36'E): A, habitus (dorsal); B, P5.

Male: C, habitus (dorsal); D, left P5; E, right P5.

Nota: In Southwest Pacific males the inner extension of right P5 exopod segment 2 is terminated by a small spinule; the tips of the two spines on the left exopod segments 2+3 are actually covered in small spinules (not pitted).


Species Centropages elegans - Plate 2 of morphological figuresissued from : Park T. in Fishery Bull. Fish Wildl. Serv. U.S., 1968, 66 (3). [p.558, Plate 10, Figs.1-6].
Male (from tropical Central North Pacific: 1, habitus (dorsal); 2, right A1; 3, geniculated region of right A1; 4, P5 (anterior); 5, exopod of right P5; 6, exopod of left P5.

Nota: The proportional lengths of the prosome and urosome are 2.8:1. Cephalosome and 1st metasomal segment incompletely separated (a line of separation is visible only on the dorsal side). The urosome segments and furca are in the proportional lengths as 15:17:17:5:14:32.


Species Centropages elegans - Plate 3 of morphological figuresissued from : Park T. in Fishery Bull. Fish Wildl. Serv. U.S., 1968, 66 (3). [p.556, Plate 9, Figs.12-26].
Female (from tropical Central North Pacific): 12, habitus (dorsal view); 13, posterior part of metasome and urosome (lateral left side); 14, idem (lateral right side); 15, idem (ventral); 16, A2; 17, Md (mandibular palp); 18, Md (cutting edge); 19, Mx1; 20, Mx2; 21, Mxp; 22, P1; 23, P2; 24, P3; 25, P4; 26, P5.

Nota: The prosome is about 3 times as long as urosome. The cephalosome, dorsally, has a small semicircular projection at the tip and a knoblike process at the posterodorsal margin. Cephalosome and 1st metasomal segment incompletely separated (a line of joint is visible only on the dorsal region).
