 issued from : C. With in The Danish Ingolf-Expedition, 1915, III (4). [Pl. I, 10a, 10b]. As Spinocalanus abyssalis. Female: 10a, oral surface of the labrum; 10b, lamina labialis. Nota: Labrum : in front of the hinder margin in the middle a transverse row of long bristles is observed, but here none along the margin proper; laterally a series of short setae is observed (10a), and in front of these, partly on the oral surface, a group of short spines or granules is observed. Orally we find on each side an inner and an outer series of delicate bristles, arranged in a xhort posterior and a long anterior division. As far as the structure of the labium etc. is concerned (10b).

 Issued from : M. Bode, S. Laakmann, P. Kaiser, W. Hagen, H. Auel & A. Cornils in J. Plankton Res., 2017, 39 (4). [p.604, Table I]. Species identified via morphological and molecular analyses, including the number of specimens used for each identification method (MI: morphological identification, COI: cytochrome c oxydase subunit I gene fragment, MS: MALDI-TOF analysis, 18 S: ribosomal 18 S gene fragment). Cryptic lineages were revealed only after molecular analysis. Sampling depth, latitude, total length (TL) and Prosome/Urosome ratio (Pr:Ur) of taxon were recorded. morphological characters are only listed here, if the identification was ambiguous due to missing body parts or if cryptic or pseudocryptic lineages were revealed during molecular analyses. For diagnostic character of species refer to the references: Park, 1970; Grice, 1971; Damkaer, 1975; Schulz, 1989, 1996. C = coxa; B = basis; P = swimming legs; Exp = exopod.

Confusions between this species and S. abyssalis make some geographical localisations uncertain.
The sex of this species in Deevey & Brooks (1977) is not specified (See Remarks for S. pseudospinipes, but probably female. | | | Last update : 25/03/2020 | |
