Calocalanus neptunus  Shmeleva, 1965   (F,M)
Ref.:
Shmeleva, 1965 c (p.8, figs.F,M); 1967 a (p.1177, figs.F,M); Corral Estrada, 1970 (p.121, figs.F); 1970 a (p.13, figs.F); Corral, 1972 (n°138, p.4, 5, figs.F,M); Bradford-Grieve, 1994 (p.58, figs.F,M, fig.99); Avancini & al., 2006 (p.69, Pl. 38, figs.F,M, Rem.); Vives & Shmeleva, 2007 (p.946, figs.F,M, Rem.)
Species Calocalanus neptunus - Plate 1 of morphological figuresissued from : J.M. Bradford-Grieve in The Marine Fauna of New Zealand: Pelagic Calanoid Copepoda. National Institute of Water and Atmospheric Research (NIWA). New Zealand Oceanographic Institute Memoir, 102, 1994. [p.59, Fig.30].
Female: A, habitus (dorsal); B, last thoracic segment and urosome (lateral right side); C, P5.
Nota: The Southwest Pacific females appear to be similar to the Adriatic specimens, but differ in that the head and pedigerous 1 appear to be fused and there is an indication, in the midline, of fusion between pedigerous segments 4 and 5.


Species Calocalanus neptunus - Plate 2 of morphological figuresissued from : J. Corral Estrada in Tesis Doct., Univ. Madrid, A-129, Sec. Biologicas, 1970. [Lam.31].
Female (from Canarias Is.): 1, habitus (dorsal); 2, idem (lateral left side); 3, urosome (dorsal); 4, idem (lateral left side); 5, distal segments of A1; 6, P1; 7, urosome (dorsal (another specimen); 8, posterior part cephalothorax with P5 and urosome (lateral left side).


Species Calocalanus neptunus - Plate 3 of morphological figuresissued from : J. Corral Estrada in Tesis Doct., Univ. Madrid, A-129, Sec. Biologicas, 1970. [Lam.32, figs.1-4].
Female: 1, P2; 2, P3; 3, P4; 4, P5.


Species Calocalanus neptunus - Plate 4 of morphological figuresissued from : A.A. Shmeleva in Zool. Zh., 1967, 46 (8). [p.1178, Fig.3].
Female (from Ionian Sea): 1, habitus (dorsal); 2, urosome (dorsal); 3, rostrum (lateral); 4-8, P1 to P5.
Nota: Head and 1st pedigerous somite separate, 4th and 5th pedigerous somites fused. Rostrum well developed, bifurcated. A1 slightly exceeding the body length; 24-segmented, the last one almost 2.5 times longer than the penultimate. P5 3-segmented, symmetrical, the last segment is 2.5 times longer than the preceding one, armed with 2 massive terminal setae, the inner being more than twice as long as the outer one, at the base of these seta there is a crown of small spinules.Genital segment oval, convex in ventral view, with a very well distinguished spherical spermathecae. Anal somite large, almost 3 times as long as the preceding one and 2 times as long as the caudal ramus. Symmetrical furca, short and movable, its length about twice as large as wide, 4 strong setae on each caudal ramus

Male: 9, habitus (dorsal); 10, urosome (dorsal); 11, rostrum (lateral); 12, P1; 13, P4; 14, P5.
Nota: The male looks like the female. Head and 1st pedigerous somite fused. Urosome 5-segmented. Anal somite of the same length as the two preceding ones. Caudal rami immovable, slightly asymmetrical, equaling in length to the anal somite, each ramus with 4 strong and 1 fine, inner seta. P5 asymmetrical, the left leg 4-segmented (1.6 times longer than the right leg), the right leg 3-segmented, both armed with small terminal spinules

Rem.: epipelagic- ?.
According to Shmeleva (1965, p.10) specimens have been found in the area of Middle Adriatic in the surface layer where they probably have got during the upwelling of deep-sea waters from the data in Bogdanova & Timoshchuk (in press).
