First record of Chaetacanthus magnificus (Polychaeta: Polynoidae) from the northeast coast of Brazil, with an overview of its taxonomic history

Abstract

Polynoidae is a diverse group of polychaetes known as scale-worms, found in different marine regions. However this rich family is little studied in Brazil, especially along the northeastern coast of the country. We report Chaetacanthus magnificus, a first record for the northeastern coast of Brazil, establish this species as valid, differentiating it from other synonyms found in several studies which report polychaetes in Central and South America. The polychaetes found by Project Algae of Paraíba are in the collection of Laboratory of Marine Invertebrates Paulo Young, Universidade Federal da Paraíba, Brazil.KEY WORDSPolychaetes, Polynoidae, scale-worm, South America, new record

Catalogue of sponges, cnidarians, and echinoderms from Brazil based on a historical inventory of the Invertebrate Collection Paulo Young (CIPY)

“…In total, 36 described species are housed in this collection (Table 1), of which 28 are endemic. Additionally, some new records have been cited for the Brazilian littoral based from material deposited at the CIPY (e. g. Young, 1988;Young & Christoffersen, 1984;De Assis et al, 2008Santos et al, 2009;Gondim et al, 2010Gondim et al, , 2013aGondim et al, , 2015aGondim et al, , 2018aOliveira & Christoffersen, 2013;Brito et al, 2013;Prata et al, 2014b;.…”

Inventory of mollusks from the estuary of the Paraíba River in northeastern Brazil

“…The biodiversity of marine invertebrates (mainly mollusks and polychaetes) in this coastal area has been increasingly studied (Duarte et al 2014, Santos et al 2010, Lomônaco et al 2011, De Assis et al 2012, Brito et al 2013, Fukuda et al 2013, Lima et al 2014, Prata et al 2014, Lucena et al 2015, Lima & Christoffersen 2016, 2016, however, the mollusk diversity of large areas, such as basin of the Paraiba River remains unknown.…”
