Annotated checklist of Echinoderms from Maranhão and Piauí States, Northeastern Brazil

Abstract

The present study provides the first checklist of echinoderm species that occurs in the States of Maranhão and Piauí, in Northeastern Brazil. The present compilation was produced based on an extensive bibliographical revision and on echinoderms deposited in the Invertebrate Collection Paulo Young, Federal University of Paraíba. Twenty-two species were listed, distributed into the classes Asteroidea (2 spp.), Ophiuroidea (16 spp.), Echinoidea (2 spp.), and Holothuroidea (2 spp.). The registered echinoderm diversity adds significantly to our faunistic knowledge, considering that no previous systematic compilation of echinoderms exists for this region.

A taxonomic guide to the brittle-stars (Echinodermata, Ophiuroidea) from the State of Paraíba continental shelf, Northeastern Brazil

“…In Brazil it has been recorded from the States of Amapá, Pará, Maranhão, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas (Gondim et al in press), Abrolhos islands off southern Bahia (Rathbun 1879), Bahia (Alves and Cerqueira 2000), and Rio de Janeiro (Manso 1993). Intertidal to 367.5 m. In this study it occurred between 11 and 33m.…”

“…Western Atlantic from Canada, United States, Mexico, the Antilles, Belize, Costa Rica, Panama, Colombia, Brazil, Uruguay, and Santa Cruz Province, Argentina (Bernasconi 1965, Hendler et al 1995, Hernández-Herrejón et al 2008, Martínez 2008, Benavides-Serrato et al 2011). In Brazil, from Pará, Maranhão, Ceará, Paraíba, Alagoas, Bahia (Gondim et al in press), Rio de Janeiro (H.L. Clark 1915) and, São Paulo (Borges et al 2002).…”

“…In Brazil from Amapá, Maranhão, Ceará, Bahia (Gondim et al in press), Rio de Janeiro (Rathbun 1879), and São Paulo (Netto et al 2005). Depth 1 to 126 m. Recorded herein for the first time in the State of Paraíba, between 10 and 18 m.…”

“…In Brazil from Maranhão, Ceará, Rio Grande do Norte, Pernambuco, Alagoas (Albuquerque 1986, Gondim et al in press ), and Espírito Santo (Tommasi 1970). This is the first record for the State of Paraíba.…”

Some Pycnogonida (Arthropoda: Chelicerata) from the "Paulo Young" Invertebrate Collection (CIPY) of the Federal University of Paraíba (UFPB), Brazil

“…The publication of biological information based on material deposited in the CIPY occurred punctually until the year 2000 (Young & Christoffersen 1984;Veloso & Melo 1993;Melo & Veloso 2005). Papers were produced more systematically since 2008, dealing with diverse groups, such as Crustacea (Riul et al 2008;Rodrigues et al 2009), Polychaeta (Santos et al 2008(Santos et al , 2010(Santos et al , 2011(Santos et al , 2014de Assis et al 2007de Assis et al , 2008ade Assis et al ,b, 2012Brito et al 2013), Echinodermata (Gondim et al 2013a(Gondim et al ,b, 2015Prata et al 2012Prata et al , 2014aPrata et al ,b, 2016, and Mollusca (Dias et al 2013;Lima et al 2013Lima et al , 2017aLima & Guimarães 2015;, include inventories of benthic macrofauna (Gondim et al 2011) and biological associations (Lima et al , 2017b. However, most of the available information has not been published in scientific journals, having been cited only in monographies, dissertations, thesis and congress/conference abstracts, which makes access to this information more difficult for the scientific community.…”
