Pegantha triloba Haeckel, 1879

Remarks: the distribution range provided by Ramírez & Zamponi (1981) is not based on specific records and, therefore, we did not consider that information for this species.

Distribution in South America: medusa—Pacific Ocean, Colombia to Chile, from 2°N to 30°S (Kramp 1965, 1968; Segura-Puertas 1984; Baldrich 2007); Atlantic Ocean, Brazil to Uruguay, no specific record (Ramírez & Zamponi 1981; Migotto et al. 2002).

Habitat: medusa—species with a wide vertical distribution (Chirichigno, pers. comm.).
