New records of nudibranchs (Mollusca: Gastropoda) from Bahia state, northeastern Brazil

Abstract

Although around 3,000 species of nudibranchs are known worldwide, only nearly 100 species are reported from Brazil. From Bahia State, northeastern Brazil, only seven species are listed. The current article provides four new records of nudibranchs from this region: Geitodoris pusae (Marcus 1955); Felimida paulomarcioi (Domínguez, García and Troncoso 2006); Felimida binza (Marcus and Marcus 1963) and Cadlina rumia Marcus 1955. The new records presented herein fill part of a historical gap in the species geographic distribution, and increase to eleven the number of nudibranch species known from Bahia.

Sea slugs (Gastropoda: Heterobranchia) from Rio Grande do Norte, Northeastern Brazil

“…Due to the high number of species found, almost four times higher than previously recorded, it is clear that there are still a gap of knowledge of the diversity of heterobranchs from northeastern Brazil. In the last years, different works contributed to fill part of this gap, including checklists, new records and the discovery and description of new species (e.g., Padula & Santos, 2006;García et al, 2008;Padula & Delgado, 2010;Lima & Delgado, 2011;Padula et al, 2012;Sales et al, 2013;Silva et al, 2013;Silva et al, 2014;Alvim & Pimenta, 2015;Galvão-Filho et al, 2015). However, despite this effort, the coast of Rio Grande do Norte remained almost unexplored.…”

“…The species was described by Alvim & Pimenta (2015) (Marcus, 1957;Domínguez et al, 2006;García et al, 2008;Padula et al, 2012, Sales et al, 2013Galvão-Filho et al, 2015;Padula et al, 2016).…”

“…They occur in diverse habitats and substrates, including macroalgae, rocky shores, coral reefs and are distributed from the poles to the tropical regions. Around 6,000 described species are known, of these 250 -excluding pelagic species -are recorded from Brazil, and 124 from the northeastern Brazilian coast (Padula & Absalão, 2005;García et al, 2008;Rios, 2009;Padula & Delgado, 2010;Alvim & Pimenta, 2011;Lima & Delgado, 2011;Cunha, 2011;Sales et al, 2011Alvim & Pimenta, 2013;Sales et al, 2013;Silva et al, 2013;Cunha et al, 2014;Alvim & Pimenta, 2015;Galvão-Filho et al, 2015).…”
