Systematic remarks. Bougainvillia is a well-defined genus and the medusae are easily recognized; however, species are difficult to identify. 32 species in the genus are valid, with 28 medusae species (Schuchert 2013; Nogueira et al. 2013); 8 were cited in Brazil, 7 in the medusa stage (Migotto et al. 2002). B. frondosa is completely distinct from other species of the genus because of the absence of ocelli and only two long, thick marginal tentacles per bulb (Bouillon 1999, see Table 1 in Nogueira et al. 2013).
Biological data. Unknown hydroid (Vannucci & Rees, 1961). No information is available on the biology of the species. In Brazil it is considered rare (Vannucci 1957; Navas-Pereira 1981).
