Planche 4 issued from : E. Suarez M. & A. Leon-Oropeza in Gulf and Caribbean Researc, 2000, 12. [p.38, Fig.1]. Female (from Campeche Sound, G. of Mexico): A, habitus (dorsal); B, idem (latral); C, urosome (lateral); D, idem (dorsal); E, right A1; F, P3; G, detail of P3 ctenospines; H, exopodite of P2; I, P1; J, head (lateral); K, P5. Scales in mm.
Planche 5 issued from : E. Suarez M. & A. Leon-Oropeza in Gulf and Caribbean Researc, 2000, 12. [p.39, Table I]. Characters used to separate the known species of Ctenocalanus. c/u ratio = cephalosome/urosome length ratio.
Planche 6 Issued from : V.N. Andronov in Russian Acad. Sci. P.P. Shirshov Inst. Oceanol. Atlantic Branch, Kaliningrad, 2014. [p.36, Fig.9, 4]. Ctenocalanus heronae after Vega-Perez & Bowman, 1992, 1970. 4, distal segment of exopod of A2.
Pour A. Prado-Por (1984) les épines cténoides pourraient être articulées à leur base, ainsi leur angle avec l'axe de l'exopode ne constitue pas un bon critère taxonimique. Vega-Pérez & Bowman (1992, p.100) n'observent aucun muscles attachés à la base des épines cténoides. le seul mouvement possible pourrait résulter de la flexion antero-posterieur de la patte. Pour ces derniers auteurs, la position des épines cténoides constitue un caractère valide.
