Distribution map of Neoscolecithrix watersae by geographical zones
Loc:
NW Atlant. (off S Cape Cod)
N: 1
Lg.:
(213) F: 1,86; M: 1,92-1,75; {F: 1,86; M: 1,75-1,92}
Rem.: bathypelagic (1465-1500 m), hyperbenthic.
This species resembles Neoscolecithrix koehleri Canu, 1896.
According to Campaner (1978 a, p.968) Xanthocalanus watersae (Grice, 1972) , from the structure of the P5, the species must be removed to the genus Neoscolecithrix.
