Remarks

epipelagic. Overall depth Range in Sargasso Sea: 0-500 m (Deevey & Brooks, 1977, Station "S");
C.B. Wilson (1950) reports this species for the Pacific; also present near the Tuamotu Islands (Rose, 1953), Moorea, and California (Brinton & al., 1986).
For Boxshall & Halsey (2004, p.491) the subgenus (Dahl, 1912) is considered as full generic status pending phylogenetic revision of the whole family at the generic level.
