Distribution map of Euaugaptilus nudus by geographical zones
Japan (Sagami), Indian (Arabian Sea)
N: 3
(69) F: 4,2; {F: 4,20}
Rem.: Obtained in a vertical haul from 1000 m to the surface (Matthews, 1972). Between 150-500 m in Indian Ocean (Stephen, 1984).
For Itoh (1970 a, fig.2, from co-ordonates) the Itoh's index value from mandibular gnathobase = 1050.

In ''affinis"" Group after Matthews (1972, p.64) {See remarks in Euaugaptilus genus}.
