Sampling/reporting sites.

Off the northern coast of Chile ( Schrödl 2003). On the coast of El Salvador (13°N) (Segovia and López 2015). In Peru, it was mentioned by Paredes et al. (1999) and Ramírez et al. (2003) based on the records of d’Orbigny (1854) in Callao (10°15'S). Recently reported in Isla Santa, Ancash (09°01'S) by Uribe et al. (2013).

Remarks.

Included in Paredes et al. (1999), probably based on a personal communication with Sandra Millen. The records of Glaucus distichoicus d’Orbigny, 1837 ( d’Orbigny 1854; Dall 1909; Paredes et al. 1999; Ramírez et al. 2003) do not have enough evidence to formalize the species within the genus Glaucus and could refer to G. atlanticus .
