Species Spinocalanus elongatus - Plate 6 of morphological figuresIssued 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 crypticf 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.
