“…Furthermore, the coastal zone of Bahia is recognized as a Brazilian marine biodiversity "hotspot", mainly due to the occurrence of the richest and largest coral reef complex in the South Atlantic. Despite the biological and ecological importance of this coastal zone (Leão & Ginsburg 1997, Alves & Cerqueira 2000, Leão 2002, Dutra et al 2005, Barros et al 2008, MMA 2010, Ourives et al 2011, Paz et al 2012, Moura et al 2015, Paim et al 2015, Leão et al 2016, Mazzei et al 2016, Lucena & Christoffersen 2017, there remains much to be discovered regarding the biological diversity of its ecosystems, even in the most studied regions between the Abrolhos Archipelago and Tinharé-Boipeba Environmental Protection Area.…”

The reef ecosystems of Morro de São Paulo are located in the Tinharé-Boipeba Environmental Preservation Area which was established in 1992 in the state of Bahia, Brazil. Despite this area has been created more than two decades ago, no study has provided knowledge on the invertebrate biodiversity associated with such reef ecosystems. The present investigation provides the first inventory of benthic mollusks associated with the reef ecosystems of Morro de São Paulo based on the collection of living specimens and fresh empty as well as some worn shells. Mollusks were sampled in January 2015 and August 2016 through intensive searches from the intertidal to shallow subtidal habitats of the reefs on three beaches of Morro de São Paulo. Taxonomic richness and biodiversity indices were analyzed. This rapid assessment of the malacofauna resulted in the determination of 84 species belonging to 44 families of gastropods as well as 13 species belonging to eight families of bivalves and one chiton (total: 98 species). Species richness was numerically dominated by members of the subclass Caenogastropoda. The families with the largest number of species were Ranellidae (5), Muricidae (6) and Marginellidae (7). Conus regius, Cypraecassis testiculus, Lobatus goliath, Strombus pugilis, Tonna galea, Turbinella laevigata and Vasum cassiforme are extremely vulnerable macrospecies in the region due to their commercial importance. Comparisons of the malacofauna composition between the study site and Abrolhos Bank were made from data published for this region. ACE and CHAO 1 estimated 133 mollusk species for the region. Despite the rapid assessment, the number of species discovered in the study area approached 73.6% of the estimated total number. The considerable number of mollusk species found in a relatively small area with insufficient sampling underscores the importance of the reef ecosystems of Morro de São Paulo as a one priority area for conservation on the coast of the state of Bahia, Brazil, for which the species richness of other invertebrate groups is virtually unknown.

“…Little information is found regarding pycnogonid fauna on the coast of Brazil, where the group has been scarcely and sporadically addressed in the literature (see Lucena 2016). However, there have been recent efforts regarding the study of the biodiversity of the group, which has increased knowledge on species richness in northeastern Brazil (Lucena et al 2015;Lucena 2016;Lucena & Christoffersen 2016).…”

Uma espécie de picnogonídeo classificada na família Pallenopsidae Fry, 1978 e no gênero Pallenopsis Wilson, 1881 é registrada neste estudo para a costa do estado da Paraíba (nordeste do Brasil), com base na identificação de três espécimes fêmeas coletadas na zona infralitoral em profundidades de 12 a 34 metros. Pallenopsis fluminensis (Krøyer, 1844) é a quarta espécie de Pycnogonida registrada para a região. Até então, apenas Anoplodactylus batangensis (Helfer, 1938), A. eroticus Stock, 1968 e A. mirim Lucena, Araújo & Christoffersen, 2015 haviam sido registradas para a costa da Paraíba. Pallenopsis fluminensis é diagnosticada pelo tronco com setas pequenas na borda distal de cada segmento; probóscide com setas terminais; processos laterais com pequenas setas dorsais; palpos sem setas e reduzidos a um pequeno tubérculo; quela com muitas setas, palma 1.5 vezes mais longa que larga; ovígeros com oito artículos nas fêmeas, sendo os artículos 5 e 6 subiguais, e o 8 pouco menor que o 7; e a tíbia 1 sem uma cobertura densa de setas. Até o momento, P. fluminensis é a única congênere proveniente da costa Atlântica da América do Sul sem uma densa cobertura de setas sobre a tíbia 1.Palavras chave: Arthropoda, Chelicerata, Pantopoda, Atlântico oeste, região tropical, zona costeira.Abstract: A pycnogonid species classified in the family Pallenopsidae Fry, 1978 and the genus Pallenopsis Wilson, 1881 is recorded in this study for the coast of the state of Paraíba in northeastern Brazil based on the identification of three female specimens collected from the infralittoral zone at depths of 12 to 34 meters. Pallenopsis fluminensis (Krøyer, 1844) is the fourth species of Pycnogonida recorded for the region. To date, only Anoplodactylus batangensis (Helfer, 1938), A. eroticus Stock, 1968 and A. mirim Lucena, Araújo & Christoffersen, 2015 have been recorded for the coast of the state of Paraíba. Pallenopsis fluminensis is diagnosed by a trunk with small setae on the distal border of each segment; proboscis with terminal setae; lateral processes with small setae; palps without setae and reduced to a small knob; chela with many setae, palm 1.5 times longer than wide; ovigers with eight articles on females, articles 5 and 6 subequal and article 8 not much smaller than 7; and tibia 1 without dense cover of the setae. To date, P. fluminensis is the only congener from the Atlantic coast of South America without a dense cover of setae on tibia 1.Key words: Arthropoda, Chelicerata, Pantopoda, Western Atlantic, tropical region, coastal zone.
