Espèce Pareucalanus langae - Planche 1 de figures morphologiquesissued from : J.M. Bradford-Grieve in The Marine Fauna of New Zealand: Pelagic Calanoid Copepoda. National Institute of Water and Atmospheric Research (NIWA). New Zealand Oceanographic Institute Memoir, 102, 1994. [p.81, Fig.43].
Female (from Fleminger, 1973, p.991, fig.15 b. As Eucalanus langae): A, habitus (dorsal and lateral pattern of integumental organs (black point = sites occuring at 100% frequency, o = 80-99% frequency, x = 10-79% frequency, triangle are sites which are also visible in lateral view but which are assigned to dorsal sets). Female (from south-west Pacific): B, habitus (dorsal); C, urosome (dorsal); D, genital segment (lateral right side); E, Md (mandibular palp).

Male (from Fleminger, 1973, p.994, Fig.18p. As Eucalanus langae): F, urosome and P5 (lateral right side).


Espèce Pareucalanus langae - Planche 2 de figures morphologiquesissued from : A. Fleminger in Fishery Bull. natn. Ocean. Atmos. Adm., 1973, 71 (4). [p.968, Fig.1, t (p.969). As Eucalanus langae.
Female: t, genital segment (lateral right side).


Espèce Pareucalanus langae - Planche 3 de figures morphologiquesissued from : A. Fleminger in Fishery Bull. natn. Ocean. Atmos. Adm., 1973, 71 (4). [p.994, Fig.18]. As Eucalanus langae.
Female (from 32°29'S, 09°04'E): h, forehead (ventral)

Male (31°11'S, 00°56'E): p, urosome and P5 (lateral right side).


Espèce Pareucalanus langae - Planche 4 de figures morphologiquesissued from : A. Fleminger in Fishery Bull. natn. Ocean. Atmos. Adm., 1973, 71 (4). [p.991, Fig.15 Ab, Bb]. As Eucalanus langae.
Female: a, habitus (dorsal); a', idem (lateral right side).
Dots represent sites occuring at a frequency of 100% in the pooled sample of the species, open circles are sites appearing in 80 to 99%, crosses are sites occupied in from 10 to 79%. Open triangles are sites also visible in lateral view but assigned to tergal sets.


Espèce Pareucalanus langae - Planche 5 de figures morphologiquesissued from : J.M. Bradford in N.Z. Jl Mar. Freshw. Res., 1970, 4 (4). [p.352, Figs 6-9]. As Eucalanus attenuatus.
Female (off Kaikoura, New Zealand): 9, urosome (dorsal).

Male: 6, Md (mandibular palp); 7, P5; 8, urosome (dorsal).

Scale bars represent 0.1 mm.

Nota: The New Zealand specimens differ from Giesbrecht's (1892) description in details of the mandibular palp: basipod 2 bears 4 small setae; the endopod of segment 1 has 2 small setae, segment 2 has 5 setae (2 of which are slenderer than the rest). The females and stage V males from New Zealand only the anal segment is hairy and the adult males have a naked urosome.
