Species Mimocalanus cultrifer - Plate 11 of morphological figuresIssued from : M. Bode, S. Laakmann, P. Kaiser, W. Hagen, H. Auel & A. Cornils in J. Plankton Res., 2017, 39 (4). [p.603, 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; End = endopodite; P = swimming legs; End = endopodite; Exp = exopodite.

Distribution map of Mimocalanus cultrifer by geographical zones
Species Mimocalanus cultrifer - Distribution map 4issued from : W. Vervoort in B.A.N.Z. Antarctic Reseach Expedition, Reports - Ser. B, Vol. III, 1957 [Fig.11]
Chart showing the geographical distribution (white triangle) in the seas surrounding the Antarctic continent.
Nota: In this chart the area frequented by whaling vessels has been hatched. The Antarctic circle (66°.5 S) has been drawn as a broken line. The numbers I to VI refer to the sectors into which the Antarctic seas are divided according to Mackintosh (1942) (after Vervoort, 1951).

(SE, NE, NW), Brazil, off Amazon, Canary Is., off W Cabo Finisterre, Bay of Biscay, Caribbean Sea, Caribbean Colombia, G. of Mexico, off Bermuda, off S Cape Cod, off W Ireland, Medit. (Alboran Sea, Thyrrenian Sea, Ligurian Sea, Ionian Sea, S Adriatic), Indian, Indonesia-Malaysia, China Seas (East China Sea, South China Sea), Japan, Pacif.
