Espèce Labidocera diandra - Planche 4 de figures morphologiquesissued from : A. Fleminger in Proc. U.S. natn Mus., 1967, 120 (3567). [p.21, Fig.8, l].
Copépdite stage V: l, forehead (dorsal).
Nota: head-hooks were seen in all immature copepodites from stages II to V (Secondary loss of head-hooks in the mature stage).
Remarks (p.30) The presence or absence of head-hooks in pontellids, and sepecially in Labodocera, has been widely regarded as a feature of considerable taxonomic significance. Obviously, if head-hooks can vary in occurrence intraspecifically, their usefulness to phylogeny hinges upon a thorough survey of all species in the genus.
