Park in Biology of the Antarctic Seas XI, Antarct. Res. Ser, 1982, 34. [p.111, Fig.21]. Female: a, forehead (lateral); b, last thoracic segment and urosome (lateral left side); c, genital segment (lateral); d, P1 (anterior); e, P2 (posterior); f, P3 (posterior); g, P5 (posterior); h, distal part of inner spine of P5. Nota: Urosome about 29/100 length of prosome. All cephalosomal pappendages seem similar to those of S. major. The species differs from S. major by anterior surface spinulation of P1.

 Issued from : T. S. Park in Bull. Mar. Sc., 1970, 20 (2). [p.506, Figs.147-153]. As Scaphocalanus major. Female (from Caribbean Sea & G. of Mexico): 147, habitus (lateral right side); 148, rostrum (anterior view); 149, P1 (anterior); 150, P2 (posterior); 151, P3 (posterior); 152, P4 (posterior); 153, P5. Nota: prosome a little more than 3 times length of urosome. P5 2-segmented, the external spine small and often absent.

 Issued from : G.O. Sars in Résult. Camp. Scient. Prince Albert I, 69, pls.1-127 (1924). [Pl.XLIX, figs.1-8]. Female: 1, habitus (dorsal); 2, idem (lateral left side); 3, rostrum; 4, P1; 5, P2; 6, endopodal segments of P3; 7, endopodal segments of P4; 8, P5.

Fauna SSSR, 1950, 35 (Israel Program for Scientific Translations, Jerusalem, 1967) [p.251, Fig.158]. With doubt. Female (from NW Pacif.): habitus (dorsal and lateral right side); S5, P5. Male: habitus (dorsal; S5, P5. Nota: Pacific specimens are larger than the Atlantic ones; they also differ in the length ratio of the inner bristle of P5 in female.

 issued from : C.B. Wilson in Scientific Results of Cruise VII of the Carnegie during 1928-1929. Biology-I. Carnegie Inst. Wash. Publ. 536, 1942. [p.233, Fig.136]. With doubt. Female (from SE Pacific): 136, P5. Nota: Head without crest. The structure of P5 is quite different from that in the other authors.

Sometimes confused with Scaphocalanus major, as yet they are not synonymous. According to Vervoort (1965, p. 63) the described form under this designation by Brodsky, 1950 (1967) is a synonym of S. major. The geographical distribution remains uncertain. | | | Last update : 25/10/2022 | |
