Nausithoe rubra Vanhöffen, 1902

Remarks: Nausithoe rubra is considered by some authors (Bigelow 1928; Kramp 1961) as conspecific with Nausithoe atlantica . Because there is no conclusive revision on the group, we decided to maintain both species. Distribution in South America: medusa—Pacific Ocean, Peru Current (N. Chirichigno unpublished data), Chile, from 41.5°S to 43.65°S in Chiloé interior sea (Palma et al. 2011).

Habitat: mesopelagic and bathypelagic, oceanic (Bigelow 1928; Kramp 1961).
