Espèce Talacalanus maximus - Planche 1 de figures morphologiquesissued from : O. Tanaka & M. Omori in Publ. Sero Mar. Biol. Lab., 1992, 35 (4/5). [p.267, Fig.8, g-h]. As Xanthocalanus maximus.
Female (from Izu region, Japan): g, Mx2; h, sensory filaments of terminal part of Mx2.

Nota: Re-examination of female specimen described by Tanaka & Omori (1967) revealed that the leaf-like seta on 5th lobe of Mx2 is not as long as illustrated in their report and that endopod of Mx2 armed with 1 long vermiform and 7 short brushform sensory filaments, instead of 8 bud-like filaments.
