C. crassiusculus : Farran, 1929 (p.211, 291, figs.F)
Corycaeus vitreus : Boxshall & Halsey, 2004 (p.494)
F. Dahl, 1894 (p.73); M. Dahl, 1912 (p.25, Descr.M, figs.M); Farran, 1936 a (p.134, figs.F, Rem.); Dakin & Colefax, 1940 (p.111, figs.M, Rem.); Sewell, 1947 (Rem.: p.275); Motoda, 1963 (p.221, figs.M); Chihara & Murano, 1997 (p.967, Pl.218: M);
Species Corycaeus (Corycaeus) vitreus - Plate 1 of morphological figuresissued from : O. Tanaka in J. Fac. Agricult. Kyushu Univ., 1957, 11 (1). [Pl.4, Figs.1-4].
Male (from Japanese waters): 1, habitus (dorsal); 2, idem (lateral left side); 3, A2; 4, P4.
Nota: Cephalothorax 1.5 times as long as urosome (26:17). The abdominal segments and furca in the proportional lengths 55:15:30. Anal segment is wider at the proximal than at the distal (13:11). Furcal rami 5 times as long as wide (19:4).

Species Corycaeus (Corycaeus) vitreus - Plate 2 of morphological figuresissued from : Q.-c Chen & S.-z. Zhang & C.-s. Zhu in Studia Marina Sinica, 1974, 9. [Pl.15, Figs.6-8]. As Corycaeus (Corycaeus) viretus.
Male (from China Seas): 6, habitus (dorsal); 7, A2; 8, P4.

Species Corycaeus (Corycaeus) vitreus - Plate 3 of morphological figuresissued from : G.P. Farran in Great Barrier Reef Expedition 1928-29. Scientific Reports, V, No.3. Copepoda. 1936 [p.135, Fig.28].
Female: a, habitus (dorsal); b, idem (lateral left side).
Nota: In form the female is more robust than C. crassiusculus. The urosome is shorter and broader in dorsal view, though scarcely differing when seen from the side; the furcal rami are noticeably broader and more tapered. There is a menbranous edge to the longest furcal seta, but it is narrow and tenuous and difficult to make out, and isequally present in the furcal seta of C. crassiusculus.

Nota: The characters which separate it from the males of C.clausi and C. crassiusculus are the short cephalon, very broad in front and tapering posteriorly, the short anal segment and the fine transparent edge to the longest furcal seta

Species Corycaeus (Corycaeus) vitreus - Plate 4 of morphological figuresissued from : M. Dahl in Ergebnisse der Plankton-Expedition der Humboldt-Stiftung. Bd II, G. f1. I. Die Corycaeinen 1912. [Taf.III, Figs.8-13].
Male: 8, habitus (dorsal); 9, idem (lateral left side): 10, A2; 11, Mxp; 12, P1 (distal part of exopod 3); 13, P4.

Species Corycaeus (Corycaeus) vitreus - Plate 5 of morphological figuresissued from : Z. Zheng, S. Li, S.J. Li & B. Chen in Marine planktonic copepods in Chinese waters. Shanghai Sc. Techn. Press, 1982 [p.136, Fig.84].
Male (from SE Korea): a, habitus (dorsal); b-c, urosome (lateral, right side); d, A2; e, P4.
