Taxonomy of Gigantoporidae View in CoL from Brazil

Gigantoporidae View in CoL was recently characterized by Martha et al. (2020) as having encrusting or erect colonies, large zooids with a pseudoporous lepralioid wall, orifice with a wide proximal sinus and condyles, but without spines, and notably, a raised secondary orifice forming a tubular peristome and having adventitious avicularia and spiramen. Additionally, the peristomial ovicell was characterized as having a membranous ectooecium and a pseudoporous endooecium. Bock (2024) reports that the family comprises 49 species with representatives widely reported (mainly in the tropics). According to Vieira et al. (2008), only two species of Gigantoporidae View in CoL were reported from the Brazilian coast, namely Gigantopora lyncoides and Aptonella violacea View in CoL (= Cy. violacea View in CoL n. comb.). While numerous studies have unveiled previously undocumented bryozoan biodiversity along the Brazilian coast (e.g., Almeida et al. 2015, 2021; Ramalho et al. 2018; Winston et al. 2014; Vieira et al. 2016), there have been no reports of any other gigantoporid species to date ( Vieira & Almeida 2024).

As mentioned earlier, A. violacea View in CoL is now assigned to the bitectiporid genus Cycloperiella View in CoL . Thus, the only gigantoporid reported from Brazil is Gi. lyncoides , the type species of the genus. This species is here described and imaged using SEM for the first time since its original description. Additionally, a new species of Cosciniopsis View in CoL from Brazil is described below.
