Zanclea costata Gegenbaur, 1856a

Remaks: doubtful identification of the medusa stages, especially in southeastern Brazilian waters (20°S to 25°S) due to the recent synonymy of the polyp stage present in this area with Z. migottoi (cf. Galea 2008 p. 14–16).

Distribution in South America: medusa—Atlantic Ocean, Brazil to Uruguay, from 20°S to 25°S, from 29°S to 35°S (Vannucci 1957; Navas-Pereira 1974, 1981, 1984; Ramírez & Zamponi 1981; Migotto et al. 2002; Silveira & Morandini 2011; Miranda et al. 2015).

Habitat: medusa—neritic, eurythermic and euryhaline species (Vannucci 1957; Navas-Pereira 1974).
