O objetivo deste trabalho foi estudar a ecologia populacional de Callichirus major (Say, 1818) na praia de Piedade, Estado de Pernambuco, Brasil, através da análise de parâmetros como proporção sexual, período reprodutivo e o recrutamento de juvenis nesta população. As coletas foram realizadas mensalmente entre dezembro de 2010 e novembro de 2011. A temperatura do ar e das tocas, além da salinidade da água do mar foram medidas in situ. O teste t de Student foi aplicado para comparar os valores dos fatores abióticos entre as estações seca e chuvosa. A proporção sexual foi analisada para cada mês e durante todo o período estudado, e o teste do qui-quadrado foi aplicado para verificar se desvia significativamente da proporção esperada. O período reprodutivo foi determinado com base na frequência de fêmeas ovígeras. O recrutamento foi obtido com base na frequência de indivíduos imaturos. A influência de fatores abióticos na população foi avaliada através do coeficiente de Pearson. A temperatura do ar e das tocas variou significativamente entre os períodos seco e chuvoso, com valores mais elevados no período seco. Um total de 389 indivíduos C. major foram amostrados (174 ♂ e 215 ♀). A razão sexual foi de 1:1,24 (♂:♀), as fêmeas foram mais abundantes que os machos. No presente estudo, foi observado que o pico da fase reprodutiva e frequência de fêmeas ovígeras de C. major ocorreu na estação seca (verão equatorial). O recrutamento de jovens na população ocorreu durante todo o ano, especialmente entre o verão e o outono. De acordo com a matriz de correlação, o fator abiótico mais influente na abundância de C. major, especialmente em fêmeas ovígeras, é a temperatura das tocas. Este estudo cria uma linha de base para futuras pesquisas com C. major no Nordeste do Brasil.

The aim of this paper was to study the population ecology of Callichirus major (Say, 1818) at Piedade Beach, State of Pernambuco, Brazil, through the analysis of parameters such as sex ratio, reproductive period and recruitment of juveniles into this population. Sampling was taken monthly from December 2010 to November 2011. The burrow and air temperatures, as well as the sea water salinity, were measured in situ. A Student t test was applied to compare the value of abiotic factors between the dry and rainy seasons. The sex ratio was analyzed for each month and for the total studied period, and a Chi-square test was applied to verify if it deviated significantly from the expected proportion. The reproductive period was determined based on the frequency of ovigerous females. The recruitment was obtained based on the frequency of non-mature individuals. The influence of the abiotic factors was evaluated through a Pearson’s coefficient. The air and burrow temperatures varied significantly between the dry and rainy periods, with the highest values in the dry period. A total of 389 individuals of C. major (174 ♂ and 215 ♀) were sampled. The sex ratio was 1:1.24 (♂:♀), with females being more abundant than males. In this study, the most active reproductive period of C. major and frequency of ovigerous females was observed in the dry period (equatorial summer). Recruitment of juveniles into the population occurred throughout the year, between the summer and the autumn. According to the correlation matrix, the main abiotic factor influencing the abundance of C. major, especially of ovigerous females, was the burrow temperature. This study creates a baseline for further research with C. major in Northeastern Brazil.

The purpose of the present study was to investigate the biodiversity, relative abundance and frequency of decapod crustaceans in the marine mangrove ecosystem at Gaibu Beach, Pernambuco State, Brazil. A total of eight samples were taken: four in the rainy season (August 2010) and four in the dry season (February 2011), during spring low tides and according to the phases of the moon. In all, 352 decapods were sampled. These specimens belonged to 17 species, 14 genera and 13 families. Pachygrapsus transversus (Gibbes, 1850), P. gracilis (Saussure, 1858), Panopeus americanus Saussure, 1857 and Uca (Leptuca) leptodactyla Rathbun, 1898 were very frequent. The three latter species occurred in all samples. The most abundant species was P. americanus. The Shannon-Wiener index (H') showed that, in general, the diversity level was medium for all samples. However, the sample taken at the time of the new moon during the rainy season was classified as highly diverse. These results contribute to the knowledge of the decapod fauna inhabiting mangroves associated with fringe reefs.

A total of 39 species of Stomatopoda were previously reported from marine and estuarine habitats of Brazilian waters. The present checklist is based on material deposited in the crustacean collection of Museu de Oceanografia Petrônio Alves Coelho, Universidade Federal de Pernambuco, city of Recife, Brazil (MOUFPE). The collection, deriving primarily from the northern and northeastern coast of Brazil, includes 667 samples and 1.301 specimens, distributed in four superfamilies, seven families, 14 genera and 33 species, including one holotype and two paratype. Apparent distribution gaps for five-species were filled. Two Brazilian endemic species had their southern geographical ranges increased (Neogonodactylus moraisi (Fausto Filho & Lemos de Castro, 1973) and Nannosquilla dacostai Manning, 1970) and one was recorded for the first time from northeast Brazilian waters [Alima neptuni (Linnaeus, 1768)]. There are now 42 species of Stomatopoda recorded from the Brazilian coast.

This study investigated the composition and spatial distribution of the sublittoral decapods on the reefs of Porto de Galinhas Beach, southern coast of Pernambuco, Brazil, through the Underwater Visual Census technique. Data were collected monthly, at night during full-moon tides in low tide periods from June 2004 to May 2005, using SCUBA diving and a visual census with a fixed belt transect (20 m long). Three sampling areas were defined: Confined Waters (low hydrodynamics) with shallow sites (up to 2.5 m deep); Semi-open Water (3 to 6 m deep), influenced by waves and tidal currents (moderate hydrodynamics); and Open Water (7 to 10 m deep), in the breaker zone (high hydrodynamics). A total of 6,287 individuals of 34 species belonging to the infraorders Brachyura (19 species), Achelata and Anomura (5 species each), Caridea (3 species), and Stenopodidea and Astacidea (1 species each) were collected. Two decapod assemblages were distinguished: in a habitat with low hydrodynamics and shallow (Confined) water; and in a habitat with moderate to high hydrodynamics and depths of 3 to 10 m (Semi-open and Open water). At the sites with high hydrodynamics, i.e., the Open-water Area in the breaker zone, decapod diversity was significantly lower than in the other, protected areas on the reef bench. These results suggest that the distribution of subtidal decapods on coastal reefs is influenced by depth and exposure to water stress caused by waves and currents (hydrodynamics). The visual census technique with SCUBA proved to be suitable for ecological studies on subtidal decapods.

The barbouriid shrimp Janicea antiguesis (Chace, 1972) is reported from Porto de Galinhas and Tamandaré in Pernambuco and Guarapari in Espírito Santo, Brazil. These records confirm the presence of J. antiguensis in northeastern and eastern Brazil, considerably extending its Brazilian range from Fernando de Noronha to southern Espírito Santo and also representing the first record of this species from mainland coastal reefs. In Brazil, J. antiguensis occurs in or near marine reef caves, typically at depths between 5 and 15 m, and can be most easily observed while scuba diving at night. Colour photographs of J. antiguensis from various Atlantic localities are provided and its colour pattern is compared to that of the closely related Indo-West Pacific barbouriid shrimp, Parhippolyte misticia (Clark, 1989). Some in situ observations are provided for the Porto de Galinhas population of J. antiguensis. Multiple observations of pairs with both individuals brooding embryos at different developmental stages suggest protandric simultaneous hermaphroditism in J. antiguensis.

A presente contribuição visa avaliar a relação largura carapaça vs. peso úmido e o fator de condição de Ucides cordatus (Linnaeus, 1763), nos manguezais dos rios Ariquindá e Mamucabas, Estado de Pernambuco, Brasil. Essas duas áreas próximas apresentam características similares de vegetação e substrato, mas exibem diferentes níveis de conservação ambiental: o rio Ariquindá é a área preservada, considerado um dos últimos rios não poluídos de Pernambuco, enquanto o rio Mamucabas sofre impactos de represamento, desmatamento e deposição de lixo. Um total de 1.298 indivíduos de U. cordatus foi coletado. Machos foram mais largos e mais pesados que as fêmeas, o que é comumente observado em Brachyura. Ucides cordatus mostrou crescimento alométrico negativo (p < 0.05), o que está provavelmente relacionado à dilatação que esta espécie desenvolve na lateral da carapaça, que abriga seis pares de brânquias. Os valores de b estiveram dentro do limite estabelecido para organismos aquáticos. Apesar do fator de condição ser considerado um importante aspecto para confirmar o período reprodutivo, visto que varia com atividades cíclicas, no presente estudo ele não esteve correlacionado com a abundância de fêmeas ovígeras. Entretanto, foi considerado um bom parâmetro para avaliar impactos ambientais, sendo significativamente menor na área impactada.

The present contribution aims at evaluating the carapace width vs. humid weight relationship and the condition factor of Ucides cordatus (Linnaeus, 1763), in the mangrove forests of the Ariquindá and Mamucabas rivers, state of Pernambuco, Brazil. These two close areas present similar characteristics of vegetation and substrate, but exhibit different degrees of environmental conservation: the Ariquindá River is the preserved area, considered one of the last non-polluted of Pernambuco, while the Mamucabas River suffers impacts from damming, deforestation and deposition of waste. A total of 1,298 individuals of U. cordatus were collected. Males were larger and heavier than females, what is commonly observed in Brachyura. Ucides cordatus showed allometric negative growth (p < 0.05), which is probably related to the dilatation that this species develops in the lateral of the carapace, which stores six pairs of gills. The values of b were within the limit established for aquatic organisms. Despite of the condition factor being considered an important feature to confirm the reproductive period, since it varies with cyclic activities, in the present study it was not correlated to the abundance of ovigerous females. However, it was considered a good parameter to evaluate environmental impacts, being significantly lower at the impacted area.

Este estudo foi desenvolvido com o objetivo de determinar o tamanho da maturidade morfológica e fisiológica de machos e fêmeas em duas populações de Ucides cordatus (Linnaeus, 1763) de Tamandaré, Pernambuco, Brasil. Os caranguejos foram coletados mensalmente (abril/2008 a março/2009) nos manguezais dos rios Ariquindá e Mamucabas, por um catador, através da técnica de braceamento, durante a maré baixa em três áreas distintas de 25 m² cada. Os caranguejos capturados foram separados por sexo e medidos (largura da carapaça, comprimento do própodo do quelípodo dos machos e largura do 5º somito abdominal das fêmeas). Além disso, os caranguejos foram caracterizados em relação ao estágio de desenvolvimento gonadal. Os caranguejos com gônadas imaturas e rudimentares foram considerados jovens, enquanto os demais foram classificados como adultos (gônada em desenvolvimento, desenvolvida, avançada ou esgotada). O tamanho da largura da carapaça no qual 50% da população de U. cordatus foi considerada madura morfologicamente foi de 38,0 mm (machos) e 35,4 mm (fêmeas) em Ariquindá, enquanto para Mamucabas estes valores foram de 37,3 e 32,9 mm, respectivamente. Na determinação da maturidade sexual fisiológica, os machos e fêmeas de Ariquindá foram considerados maduros com 38,5 e 37,8 mm, respectivamente, enquanto em Mamucabas os tamanhos obtidos foram de 36,2 e 35,8 mm. A maturidade morfológica dos machos ocorreu com tamanho superior ao das fêmeas, provavelmente devido ao seu maior investimento em crescimento somático, enquanto as fêmeas investem mais no processo reprodutivo. Os caranguejos provenientes do manguezal de Mamucabas atingiram a maturidade sexual com tamanhos inferiores aos de Ariquindá, provavelmente devido ao maior impacto verificado para este manguezal.

This study aims to determine the size at morphological and physiological maturity of males and females at two populations of Ucides cordatus (Linnaeus, 1763) from Tamandaré, Pernambuco, Brazil. Crabs were sampled monthly from April 2008 to March 2009 at the Ariquindá and Mamucabas mangroves by professional crab catchers during ebb tide in three replicates (25 m² each, 20 m between plots). Crabs collected were sexed and measured (carapace width, cheliped propodus length of males and abdomen width of the fifth somite of females). Besides, the crabs were characterized according its gonad development stage. For the physiological maturity determination, crabs were arranged in two groups: juvenile crabs (specimens that showed immature and rudimentary gonads) and adult crabs (specimens with gonads at the stages classified as developing, developed, advanced or spent). The carapace width size in which 50% of males and females were considered morphologically mature was 38.0 and 35.4 mm (Ariquindá) and 37.3 and 32.9 mm (Mamucabas), respectively. Therefore, the size at physiological maturity of males and females occurred with 38.5 and 37.8 mm (Ariquindá) and 36.2 and 35.8 mm, respectively (Mamucabas). Males attain morphological maturity at a higher size than females, probably due to a major investment in their somatic growth, while females spend their energy in the reproductive process. Crabs from Mamucabas mangrove attained sexual maturity at smaller sizes than Ariquindá, probably because the more impacted situation of the primer mangrove.

OBJETIVO: Verificar a influência do local de nascimento e do transporte sobre a morbimortalidade de recém-nascidos prematuros na Região Sul do Brasil. MÉTODOS: Estudo de coorte com recém-nascidos prematuros transferidos para a unidade de tratamento intensivo de referência (grupo transporte = 61), tendo sido acompanhados até a alta. Os dados sobre o atendimento no hospital de origem e transporte foram obtidos no momento da internação. Esse grupo foi comparado com neonatos da maternidade de referência, pareados por idade gestacional (grupo controle = 123), tendo como desfecho primário o óbito e desfechos secundários as alterações da glicemia, temperatura e saturação de oxigênio no momento da internação e a incidência de enterocolite necrosante, displasia broncopulmonar e sepses. Na associação entre as variáveis e o desfecho, foi utilizado o risco relativo. Foi adotado um nível de significância de α = 5% e β = 90%. RESULTADOS: A distância média percorrida foi de 91 km. A idade gestacional média foi de 34 semanas. Entre os recém-nascidos transferidos, 23% (n = 14) não tiveram atendimento pediátrico na sala de parto. No transporte, 33% dos recém-nascidos foram acompanhados por pediatra, e os equipamentos utilizados foram: incubadora (57%), bomba de infusão (13%), oxímetro (49%) e aparelho para aferição da glicemia (21%). O grupo transporte apresentou maior incidência de hiperglicemia, risco relativo (RR) = 3,2 (2,3-4,4), hipoglicemia, RR = 2,4 (1,4-4,0), hipertermia, RR = 2,5 (1,6-3,9), e hipoxemia, RR = 2,2 (1,6-3,0). Foram observados 18% de óbitos no grupo dos transferidos e 8,9% no grupo controle, RR = 2,0 (1,0-2,6). CONCLUSÕES: A pesquisa expõe deficiências no atendimento e transporte dos recém-nascidos, sendo necessária uma melhor organização do atendimento perinatal e do transporte na região nordeste do Rio Grande do Sul.

OBJECTIVE: To evaluate the effect of place of birth and transport on morbidity and mortality of preterm newborns in the southern region of Brazil. METHODS: This cohort study included preterm newborns transported to a reference intensive care unit (transport group = 61) and followed up until discharge. Data about care in hospital of origin and transport were obtained at admission. This group was compared with infants born in the maternity ward of the reference hospital paired according to gestational age (control group = 123). Primary outcome was death, and secondary outcomes were changes in blood glucose, temperature and oxygen saturation at admission and the incidence of necrotizing enterocolitis, bronchopulmonary dysplasia and sepsis. Relative risk (RR) was used to evaluate the association between variables and outcome. The level of significance was set at α = 5% and β = 90%. RESULTS: Mean travel distance was 91 km. Mean gestational age was 34 weeks. Of the neonates in the transport group, 23% (n = 14) did not receive pediatric care in the delivery room. During transportation, 33% of newborns were accompanied by a pediatrician, and the equipment available was: incubator (57%), infusion pump (13%), oximeter (49%) and device for blood glucose test (21%). The transport group had a greater incidence of hyperglycemia (RR = 3.2; 2.3-4.4), hypoglycemia (RR = 2.4; 1.4-4.0), hyperthermia (RR = 2.5; 1.6-3.9), and hypoxemia (RR = 2.2; 1.6-3.0). The percentage of deaths was 18% in the transport group and 8.9% in the control group (RR = 2.0; 1.0-2.6). CONCLUSIONS: This study revealed deficiencies in neonatal care and transport. Perinatal care and transport should be better organized in the northeastern region of Rio Grande do Sul, Brazil.

The fiddler crab Uca spinicarpa was presented by MJ. Rathbun; however, no original description or figures were provived. The species was presented in a key and the registration number of the type material mentioned. Thus, a redescription and figures of this species based on a specimen from the type locality are provided herein. Additional morphological characters based on specimens deposited in the National Museum of Natural History (Smithsonian Institution), Washington, DC, and in the American Museum of Natural History, New York City, as well as remarks regarding its geographic distribution are also provided.

El cangrejo violinista Uca spinicarpa fue presentado por MJ. Rathbun en 1900; sin embargo, la descripción original y las figuras son inexistentes. La especie apareció en una clave junto con número de registro del material tipo. Este trabajo pretende redescribir la especie y proveer figuras de acuerdo con un espécimen colectado en la localidad tipo. Se presentan caracteres morfológicos adicionales extraídos de especímenes depositados en el National Museum of Natural History (Smithsonian Institution), Washington, DC, y en el American Museum of Natural History, Nueva York, como también datos sobre su distribución geográfica.

The fiddler crabs Uca panacea Novak & Salmon, 1974 and Uca pugilator (Bosc, 1802) are closely related North American species that are sympatric along the north coast of Gulf of Mexico. Since U. panacea was described, there has been confusion in the identification these two species. Morphological differences between these two fiddlers have been pointed out in recent years, mainly regarding the presence of a pigment spot and granulations on the dorsal margin of carapace in U. pugilator. We report herein some intraspecific differences between the two species that we believe to be useful in avoiding misidentification among preserved specimens of these two fiddler crabs, such as the absence of the pigment spot in U. pugilator and the presence of the pigment spot and granulations on dorsal margin of carapace in U. panacea as well. Our results have also revealed that 65% of the U. pugilator specimens examined possess a gape pile in the major chela, which is not a reliable diagnostic character, but could be useful when present. The gonopods of both species were analyzed using SEM, confirming the previous statement that the sub-terminal thumb is shorter in U. panacea than in U. pugilator. Finally, as important morphological characters are missing in the original description of U. panacea, a redescription of this species is also provided.

Eiconaxius carinatus (Bouvier 1925) caracteriza-se, principalmente, por apresentar carenas laterais do rostro lisas, mero da quela maior com carena dorsal lisa, palma da quela maior exibindo carena dorsal bem nítida e dedos da quela menor de comprimento inferior ao da palma. Um exemplar foi coletado ao largo do Estado do Maranhão (00º 08' N e 44º 32' W) a 247 m de profundidade. A área de ocorrência anteriormente conhecida abrangia a Flórida e Antilhas (Santa Cruz e São Vicente), entre 161 e 339 m. Este trabalho registra pela primeira vez a família para o Brasil.

Eiconaxius carinatus (Bouvier 1925) is characterized, mostly, by smooth rostral lateral carinae, merus of major chela with smooth dorsal carina, palm of major chela with dorsal carina evident and length of fingers of minor chela less than the palm length. One specimen was collected off the state of Maranhão (00º 08' N and 44º32'W) in a depth of 247 m; this species was known previously from Florida and West Indies (Saint Croix and Saint Vincent), in depths between 161 and 339 m. This record is the first record of this family for Brazil.

Se conoce un total de 117 especies de crustáceos decápodos de agua dulce en Brasil. El conocimiento de la fauna de decápodos de las aguas continentales en el estado de Bahia, noreste de Brasil, es incipiente. A pesar de su amplio territorio y una rica red hidrográfica, solo se conoce de 13 especies de decápodos limnéticos en ese estado. El objetivo de este proyecto fue estudiar los crustáceos decápodos de algunas cuencas hidrográficas en el sureste de Bahia. El material descrito aquí se obtuvo de muestreos llevados a cabo entre 1997 y 2005. Los especímenes testigo se depositaron en las colecciones carcinológicas del Museo de Zoología, Universidade Estadual de Santa Cruz, Ilhéus, Brasil, y en el departamento de Oceanografía, Universidade Estadual de Santa Cruz, Ilhéus, Brasil. Se recolectó un total de 13 especies. Los carideos estuvieron representados por los átidos Atya scabra (Leach, 1815) y Potimirim potimirim (Müller, 1881) y los palaemónidos Macrobrachium acanthurus (Wiegmann, 1836), M. amazonicum (Heller, 1862), M. carcinus (Linnaeus, 1758), M. heterochirus (Wiegmann, 1836), M. jelskii (Miers, 1877), M. olfersi (Wiegmann, 1836), y Palaemon (Palaemon) pandaliformis (Stimpson, 1871). Los braquiuros estuvieron representados por los portúnidos Callinectes bocourti A. Milne-Edwards, 1879 y C. sapidus Rathbun, 1895, los tricodáctilos Trichodactylus fluviatilis Latreille, 1828 y el panopeido Panopeus rugosus A. Milne-Edwards, 1881. Macrobrachium heterochirus representa un nuevo registro en Bahia, y M. amazonicum se halló por primera vez en el sureste de Bahia. Se observó la existencia de dos formas diferentes extremas de T. fluviatilis. La forma A se caracteriza por el margen frontal del caparazón bordeado por gránulos conspicuos, el margen anterolateral presenta dientes desarrollados además de gránulos, y el margen posterolateral presenta granulación similar a la encontrada en el frontal. En la forma B el margen frontal es liso o tiene granulación incospicua; el margen anterolateral presenta usualmente 1-3 muescas, y los dientes, si están presentes (1-2), son pequeños; y el margen posterolateral es liso o levemente granulado.

A total of 117 species of freshwater decapod crustaceans are known from Brazil. Knowledge regarding the fauna of Decapoda from inland waters in the state of Bahia, northeast Brazil, is incipient. In spite of its wide territory and rich hydrographic net, only 13 species of limnetic decapods have been reported from that state. The objective of this contribution was to survey decapod crustaceans of some hydrographic basins in southeastern Bahia. The material described herein was obtained in samplings conducted between 1997 and 2005. voucher specimens were deposited in the carcinological collections of the Museu de Zoologia, Universidade Estadual de Santa Cruz, Ilhéus, Brazil, and Departamento de Oceanografia, Universidade Federal de Pernambuco, Recife, Brazil. A total of 13 species was collected. The carideans were represented by the atyids Atya scabra (Leach, 1815) and Potimirim potimirim (Müller, 1881) and the palaemonids Macrobrachium acanthurus (Wiegmann, 1836), M. amazonicum (Heller, 1862), M. carcinus (Linnaeus, 1758), M. heterochirus (Wiegmann, 1836), M. jelskii (Miers, 1877), M. olfersi (Wiegmann, 1836), and Palaemon (Palaemon) pandaliformis (Stimpson, 1871). The brachyurans were represented by the portunids Callinectes bocourti A. Milne-Edwards, 1879 and C. sapidus Rathbun, 1895, the trichodactylid Trichodactylus fluviatilis Latreille, 1828 and the panopeid Panopeus rugosus A. Milne-Edwards, 1881. Macrobrachium heterochirus represents a new record from Bahia, and M. amazonicum is reported for the first time in southeast Bahia. The occurrence of two extreme different forms of T. fluviatilis was observed. Form A is characterized by the frontal margin of carapace bordered by conspicuous granules, the anterolateral margin provided with developed teeth plus granules, and the posterolateral margin provided with granulation similar to that found on the front. In form B the frontal margin is smooth or has an inconspicuous granulation; the anterolateral margin is usually provided with 1-3 notches, and teeth (1-2), if present, are small; and the posterolateral margin is smooth or slightly granulated.

The coast of the state of Bahia in eastern Brazil comprises more than 12% of tire entire Brazilian coast. However, the crustacean fauna of this area still remains poorly known, especially the shallow-water fauna. We provide here a list of 162 brachyuran crustaceans known for the Bahia coast, based on published records as well as material deposited in the Carcinological Collection of the Universidade Estadual de Santa Cruz, Ilhéus, Bahia. The list includes estuarine and marine species (from coastal beaches to the continental shelf and slope) that have been reported at least once in the study area. Regarding longitudinal distribution patterns, five species are circum-tropical, nine are amphi-Atlantic, and two are amphi-American. The portunid Charybdis hellerii (A. Milne-Edwards, 1867) is an introduced Indo-West Pacific species. The remaining 145 species are native to the western Atlantic; 17 of these are endemic to Brazil. A total of 46 species (28.4%) have the southernmost limit of their known ranges in the western Atlantic between Bahia and the state of Rio de Janeiro, which suggests, for this group, the existence of a wide transition area between the Brazilian and Paulista zoogeographic provinces. Finally, two small range extensions in the western Atlantic are reported: the hymenosomatid Elamena gordonae Monod, 1956 from Camamu Bay (13°54'14"S) to Nova Vicosa (17°53'00.9"S), and the sesarmid Sesarma curaçãoense De Man, 1892 from Ilhéus (15°04'58.6"S) to Mucuri (18°05'38'S).

La costa del Estado de Bahia, situado en el este de Brasil, comprende más del 12% de la costa brasileña. Sin embargo, la fauna de crustáceos de esta area aún se encuentra pobremente conocida, sobretodo aquella de aguas someras. Se presenta una lista de 162 especies de crustáceos braquiuros conocidos de esta costa, en base a registros publicados y al material depositado en la Colección Carcinológica de la Universidade Estadual de Santa Cruz, Ilhéus, Bahia. La lista incluye especies estuarinas y marinas (desde playas costeras hasta la plataforma continental y talud) que han sido reportadas por lo menos una vez para el area de estudio. En cuanto a los patrones de distribución longitudinal, cinco especies son circumtropicales, nueve anfi-Atlánticas, dos anfi-Americanas, y el portúnido Charybdis hellerii (A. Milne-Edwards, 1867) es una especie introducida, nativa del Indo-Pacífico oriental. Las restantes 145 especies son nativas del Atlántico occidental, 17 de las cuales son endémicas de Brasil. Un total de 46 especies (28.4%) tienen su límite sur de distribución en el Atlántico occidental, entre Bahia y el Estado de Rio de Janeiro, lo que sugiere, para el grupo estudiado, la existencia de una amplia zona de transición entre las provincias zoogeográficas Brasileña y Paulista. Finalmente, se reporta dos ampliaciones de ámbito en el Atlántico occidental: el himenosomátido Elamena gordonae Monod, 1956 desde Bahia de Camamu (13°54'14"S) a Nova Vicosa (17°53'00.9"S), y el sesármido Sesarma curaçãoense De Man, 1892 desde Ilhéus (15°04'58.6"S) a Mucuri (18°05'38'S).

Este trabalho reporta a ocorrência de Austinixa bragantina Coelho, 2005; A. leptodactyla (Coelho, 1997) e Zaops ostreum (Say, 1817) para o litoral do Estado do Ceará, sendo estes os primeiros registros de representantes da família Pinnotheridae De Haan, 1883 para a costa cearense. A. bragantina foi coletada em maio e junho de 1995, na praia do Futuro, município de Fortaleza (3°42'S, 38°27'W). Esta espécie era conhecida, até o momento, apenas de sua localidade tipo, Ilha Canela, município de Bragança, Pará. A. leptodactyla foi coletada em novembro de 2004, na praia da Baleia, município de Itapipoca (3°08'S, 39°27'W) e Z. ostreum foi obtido a partir do exame de ostras da espécie Crassostrea rhizophorae Guilding, 1828, coletadas em novembro de 2005 no estuário do Rio Jaguaribe, município de Fortim (4°24'S, 37°46'W). São apresentadas considerações biogeográficas sobre as três espécies assim como uma lista atualizada de todos os pinoterídeos do litoral brasileiro e sua distribuição geográfica.

This study reports the occurrence of Austinixa bragantina Coelho, 2005; A. leptodactyla (Coelho, 1997) and Zaops ostreum (Say, 1817) for the State of Ceará, Northeast Brazil. These records represent the first account of the family Pinnotheridae de Haan, 1883 for the coast of Ceará. A. bragantina was collected on May and June 1995 at Futuro Beach, municipality of Fortaleza (3°42'S, 38°27'W). This species was previously known only for the type locality, Canela Island, Bragança, Pará, Brazil. A. leptodactyla was collected on November 2004 at Baleia Beach, municipality of Itapipoca (3°08'S, 39°27'W) and Z. ostreum was obtained from the oyster Crassostrea rhizophorae Guilding, 1828, collected on November 2005 at the Jaguaribe River estuary, municipality of Fortim (4°24'S, 37°46'W). Biogeographic considerations regarding the three species and an updated list of all known Brazilian pinnotherid species along with their_geographic distribution are also provided.
