The auchenipterid catfish genus Tatia is revised. Twelve species are recognized including three described as new. Tatia is diagnosed by the hyomandibula elongated anterodorsally, the anal-fin base of adult males reduced in length, and the caudal peduncle laterally compressed and deep with a middorsal keel. Tatia aulopygia occurs in the Madeira river drainage and is distinguished by the reduced cranial fontanel in adults and male modified anal fin with middle rays reduced in length. Tatia boemia, known from the upper Uruguay river drainage, is distinguished by its unique color pattern with dark chromatophores on the sides of body. Tatia brunnea from river basins in Suriname and French Guiana and the Negro river drainage, Amazon basin, is recognized by its wide head and mouth and by the male modified anal fin with sharply pointed tip. Tatia dunni, from the upper Amazon basin, is recognized by its narrow head, long postcleithral process in some specimens, and body coloration with irregular blotches or stripes. Tatia galaxias, endemic to the Orinoco river basin, is distinguished by its large eye and short snout. Tatia gyrina, distributed in the upper and central Amazon basin and in northern Suriname, has a uniquely reduced mesethmoid, slightly protruding lower jaw, second nuchal plate with slightly concave lateral borders, third nuchal plate reduced, small prevomer, low number of ribs, low number of vertebrae and sexual dimorphism regarding intumescent male genital papilla. Tatia intermedia, recorded from central and lower Amazon basin, Tocantins river, and coastal drainages in Guyana, Suriname, French Guiana, and eastern Pará State, Brazil, is distinguished by the short postcleithral process, small eye and long snout. Tatia neivai, from the upper Paraná river , Paraguay river and upper Paraíba do Sul river basin, is distinguished by its unique vertebral count and caudal-fin coloration consisting of transverse dark bars. Tatia strigata, from central Amazon basin and Negro river, is distinguished by its horizontally striped color pattern and the modified male anal fin with middle rays reduced in length. Tatia caxiuanensis, a new species described from the Curuá river, lower Amazon basin, is recognized by its wide cranial fontanel and distinctive anal fin in mature males. Tatia meesi, a new species described from the Essequibo river basin, Guyana, is distinguished from congeners by the cranial fontanel with two separate openings and thin nasal bone. Tatia nigra, a new species described from the central Amazon basin, is distinguished by its short postcleithral process, low number of vertebrae, and dark color pattern. All twelve species of Tatia are described or redescribed and a key to species is provided.

Glanidium botocudo, new species, is described from the tributaries to the upper rio Doce and Mucuri, eastern Minas Gerais State, Brazil. It represents the northernmost record of a centromochlin catfish from the coastal rivers of the Northeastern Atlantic Forest. Glanidium botocudo is readily distinguished from its congeners, except Glanidium albescens, by the whitish grey body coloration with evenly spaced small dark brown dots. The new species has a long sharpened ventral process on the urohyal, an uncommon condition among congeners, and the lowest vertebral count among the large-sized Glanidium, 36-37. It differs from Glanidium albescens by proportional measurements and higher number of ribs. Glanidium botocudo and Glanidium albescens are probably sister species, exhibiting similar morphological features and a complimentary distribution pattern, associated to an allopatric distribution pattern. Glanidium bockmanni is transferred to the genus Centromochlus

Ecology - Abstract
The susceptibility of streams to anthropogenic interference raises the need for continuous assessment of their environmental condition. From early studies to recent approaches, metrics derived from fish assemblages have proven to be fundamental tools in evaluating the ecological condition of watercourses. We assessed the environmental degradation of streams inside and surrounding the Córrego Grande Biological Reserve, state of Espírito Santo, Brazil, to develop and apply a biotic index for this region based on fish metrics. We performed samplings in 19 stream sites along 2012, 2018 and 2019, and collected 24 species belonging to five orders, 11 families, and 21 genera. The sites were classified as least-disturbed (N = 9, all within the protected area), intermediate (N = 8), and most-disturbed (N = 2). Ordination analyses distinctly separated the sites according to their disturbance classes, revealing that the percentage of native vegetation cover in 100 m buffers and type of riparian vegetation played an important role in the environmental quality of these sites. From the initial 38 metrics, three were able to distinguish between disturbance classes: percentage of Siluriformes and Characiformes species, percentage of nektonic species, and percentage of omnivorous individuals. Our results show that these metrics are significant factors to be considered in monitoring the environmental degradation of Atlantic Forest streams.

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change. There are no copyright restrictions on the data, and please cite this data paper when using the data in publications.

A hypothesis of phylogenetic relationships is presented for species of the South American catfish subfamily Centromochlinae (Auchenipteridae) based on parsimony analysis of 133 morphological characters in 47 potential ingroup taxa and one outgroup taxon. Of the 48 species previously considered valid in the subfamily, only one, Centromochlus steindachneri, was not evaluated in the present study. The phylogenetic analysis generated two most parsimonious trees, each with 202 steps, that support the monophyly of Centromochlinae composed of five valid genera: Glanidium, Gephyromochlus, Gelanoglanis, Centromochlus and Tatia. Although those five genera form a clade sister to the monotypic Pseudotatia, we exclude Pseudotatia from Centromochlinae. The parsimony analysis placed Glanidium (six species) as the sister group to all other species of Centromochlinae. Gephyromochlus contained a single species, Gephyromochlus leopardus, that is sister to the clade Gelanoglanis (five species) + Centromochlus (eight species). Based on the new taxonomic arrangement herein, BalroglanisGrant 2015 and SauronglanisGrant 2015 are placed in the synonymy of Centromochlus. Tatia is the most diverse genus within Centromochlinae, with twenty-six species in three monophyletic clades. The species composition of Tatia differs from that of Calegari et al. (2019). DuringlanisGrant 2015 and FerrarissoaresiaGrant 2015 are considered synonyms of Tatia. All generic taxa within Centromochlinae are diagnosed based on synapomorphic morphological characters. An identification key for Centromochlinae is provided.

Sarcoglanidinae and Glanapteryginae catfishes are among the most unusual elements of the Neotropical freshwater fish fauna. Microcambeva ribeirae, M. barbata and M. draco are miniaturized Sarcoglanidinae known to occur in sandy microhabitats in drainages of the Brazilian Atlantic Forest. Due to their specific habitats, specimens of Microcambeva are rare in fish collections, and new records are considered noteworthy to warrant report. Recently, specimens of this genus were newly found in the Rio Doce basin in Minas Gerais and Espírito Santo States. Such new records expand the known geographic distribution of Microcambeva. Further records of Microcambeva for Rio Peruípe in south Bahia State are also reported. Comments on the distribution of Microcambeva species along the Atlantic Forest coastal basins and suggestions on its conservation status are also offered.

- Abstract
A riqueza hidrológica da região de drenagem dos riachos litorâneos da Costa do Descobrimento é contrastante em relação a ainda pouco conhecida fauna de peixes. Para conhecimento da ictiofauna, foram averiguados 29 pontos em rios e córregos regionais. Foram contabilizadas 35 espécies, incluindo registros históricos e recentes, pertencentes a 17 famílias em 8 ordens. A grande maioria dos peixes capturados na bacia foram Ostariophysi, com 23 espécies capturadas, seguidos pelos Perciformes (5 espécies), Anguilliformes e Cyprinodontiformes (2 espécies cada), e ainda Gasterosteiformes e Synbranchiformes (1 espécie cada). A única espécie exótica reconhecida na bacia foi Oreochromis niloticus. A avaliação dos dados de distribuição das espécies nas bacias litorâneas da costa do descobrimento foi feita através do método PAE baseado em quadrículas. Quatro quadrículas irregulares foram desenhadas para as distintas regiões: Cumuruxatiba, Cahy, Corumbau e Caraíva. Para avaliação do endemismo foram analisadas as distribuições de 30 espécies de peixes de água doce. Foi construída uma matriz de dados analisada por intermédio dos softwares Winclada e NONA. Com base nos dados submetidos, foi encontrada uma única árvore parcimoniosa, dispensando o uso de cladograma de consenso. O cladograma de área continha 36 passos, índice de consistência (CI) 83 e índice de retenção (RI) 62. A análise de dados de distribuição das espécies definiu a bacia do rio Caraíva como área basal em relação às demais regiões, que formam um clado monofilético. O conjunto de áreas formado pelos rios de Cumuruxatiba e rio Cahy foi identificado como proximamente relacionado, e o grupo irmão da região do Corumbau. Acentuado endemismo foi reconhecido para a área de estudo. Espécies ameaçadas de extinção, como Mimagoniates sylvicola e Rachoviscus graciliceps foram registradas para a bacia, bem como também Acentronichthys leptos e Aspidoras virgulatus espécies características de ambientes vegetados.

A Reserva Biológica de Sooretama é a maior floresta nos tabuleiros costeiros ao norte do Espírito Santo, localizada no terço inferior da bacia do rio Barra Seca. Uma grande variedade de pequenos peixes de riacho habita os córregos protegidos pela reserva. Destaca-se a presença de riachos florestados, de águas escuras e ácidas, e ainda grandes lagoas e ambientes temporários na reserva e entorno. Especial atenção se faz necessária aos trechos a montante da unidade, pela degradação das nascentes e terço médio. Foram descritos os ambientes aquáticos e a composição taxonômica de peixes para a bacia do rio Barra Seca, incluindo 15 pontos de amostragem nos terços superior e médio, 28 no trecho baixo e 14 no Vale do Suruaca. Foram identificadas 89 espécies, pertencentes a 42 famílias e 17 ordens. Destas 39 são espécies marinhas que frequentam o estuário. Considerando todas as espécies de peixes encontradas na região, a ordem mais numerosa foi Perciformes com 26 espécies, seguida por Siluriformes com 18 espécies e Characiformes com 16 espécies. Algumas espécies foram encontradas unicamente no trecho do Vale do Suruaca, correspondendo a 48 do total de espécies. Espécies raras e ameaçadas de extinção foram reportadas historicamente para a reserva, mas não encontradas por nós nas amostragens recentes. Para manutenção da ictiofauna na bacia do rio Barra Seca e Vale do Suruaca se faz necessário estabelecer metas para preservar os ambientes de vida da biota aquática. Algumas medidas de proteção são sugeridas no texto visando conservar os córregos e sua biota.

O presente estudo investigou a distribuição das comunidades de peixes de riacho do Córrego Valsugana Velha, Santa Teresa, Espírito Santo, comparando os resultados com registros prévios em literatura. Foram amostrados 13 pontos georreferenciados. Contabilizou-se 15 espécies, entre os registros históricos e recentes em cinco ordens e 10 famílias. A grande maioria pertence às ordens Siluriformes e Characiformes com seis e cinco espécies respectivamente. Nossos resultados evidenciam que a alta riqueza de espécies para o Córrego Valsugana Velha. É provável que, na tentativa de evitar a poluição na calha principal, algumas espécies encontrem refúgio em pequenas sub-bacias, como a do Córrego Valsugana Velha, ainda relativamente vegetadas e com águas limpas. É desejável a conservação daquele Córrego de modo a contribuir para a preservação da bacia do rio Timbuí como um todo.

The South Espírito Santo river basins include the Rio Itapemirim basin, the small river basins in Marataízes and a portion of the Rio Itabapoana basin, in Southeast Brazil. Nighty-two geo-referenced sites were sampled: 23 in Itabapoana, 66 in Itapemirim and three in Marataízes. A species list has been prepared, giving habitat details. Seventy-nine species, in 31 families and 11 orders were, reported, 17 species being from marine or brackish-water/estuarine habitats. The great majority of freshwater species belong to the Siluriformes (29 species), followed by the Characiformes (19). Torrential rivers, protected by the Caparaó mountains, display the lowest richness, with only a few species recorded from the highest valleys. On the other hand, in lowland river valleys along the Serra das Torres, an exceptional diversity of stream fishes was observed. Because of the only known population of Trichogenes claviger, a relictual species of Trichomycteridae, in the river Caxixe, this area is highly strategic in planning conservation of the Icthyofauna of the Itapemirim basin. Some species from southern Espírito Santo were described based on material collected on the historic Thayer Expedition, which crossed the region in 1865. Likewise, Oligosarcus acutirostris, Astyanax microschemos and Trichogenes claviger were also described based on fishes from southern Espírito Santo. A high endemism of freshwater species was observed between southern Espírito Santo rivers and lower Paraíba do Sul, suggesting a common history among these rivers.

Imparfinis borodini Mees & Cala, 1989 is recorded in low population abundance in the upper Paraná, Tocantins and São Francisco river drainages according to the scientific literature and available collection data, but it has not been previously recorded from a coastal Brazilian river. Herein, the geographic range of this species is extended to the Rio de Contas basin in northeastern Brazil. This represents the first record in a coastal system. Additionally, I. borodini was captured in the middle Rio São Francisco at Barreiras. Both new records are the first from Bahia state, Northeastern Brazil.

The auchenipterid catfish genus Tatia is revised. Twelve species are recognized including three described as new. Tatia is diagnosed by the hyomandibula elongated anterodorsally, the anal-fin base of adult males reduced in length, and the caudal peduncle laterally compressed and deep with a middorsal keel. Tatia aulopygia occurs in the Madeira river drainage and is distinguished by the reduced cranial fontanel in adults and male modified anal fin with middle rays reduced in length. Tatia boemia, known from the upper Uruguay river drainage, is distinguished by its unique color pattern with dark chromatophores on the sides of body. Tatia brunnea from river basins in Suriname and French Guiana and the Negro river drainage, Amazon basin, is recognized by its wide head and mouth and by the male modified anal fin with sharply pointed tip. Tatia dunni, from the upper Amazon basin, is recognized by its narrow head, long postcleithral process in some specimens, and body coloration with irregular blotches or stripes. Tatia galaxias, endemic to the Orinoco river basin, is distinguished by its large eye and short snout. Tatia gyrina, distributed in the upper and central Amazon basin and in northern Suriname, has a uniquely reduced mesethmoid, slightly protruding lower jaw, second nuchal plate with slightly concave lateral borders, third nuchal plate reduced, small prevomer, low number of ribs, low number of vertebrae and sexual dimorphism regarding intumescent male genital papilla. Tatia intermedia, recorded from central and lower Amazon basin, Tocantins river, and coastal drainages in Guyana, Suriname, French Guiana, and eastern Pará State, Brazil, is distinguished by the short postcleithral process, small eye and long snout. Tatia neivai, from the upper Paraná river , Paraguay river and upper Paraíba do Sul river basin, is distinguished by its unique vertebral count and caudal-fin coloration consisting of transverse dark bars. Tatia strigata, from central Amazon basin and Negro river, is distinguished by its horizontally striped color pattern and the modified male anal fin with middle rays reduced in length. Tatia caxiuanensis, a new species described from the Curuá river, lower Amazon basin, is recognized by its wide cranial fontanel and distinctive anal fin in mature males. Tatia meesi, a new species described from the Essequibo river basin, Guyana, is distinguished from congeners by the cranial fontanel with two separate openings and thin nasal bone. Tatia nigra, a new species described from the central Amazon basin, is distinguished by its short postcleithral process, low number of vertebrae, and dark color pattern. All twelve species of Tatia are described or redescribed and a key to species is provided. O gênero Tatia de auquenipterídeos é revisado. Doze espécies são reconhecidas incluindo três descritas como novas. Tatia é reconhecido pelo hiomandibular fortemente fendido anterodorsalmente, base da nadadeira anal de machos maduros reduzida em tamanho, e pelo pedúnculo caudal lateralmente comprimido e alto com uma quilha médio-dorsal. Tatia aulopygia ocorre na drenagem do rio Madeira e é distinguida pela fontanela craniana reduzida em adultos e pela nadadeira anal em machos maduros fendida, pela redução em tamanho dos raios medianos. Tatia boemia, conhecida da drenagem do alto rio Uruguai, é reconhecida por seu padrão de colorido único com cromatóforos escuros pelas laterais do corpo. Tatia brunnea, de bacias hidrográficas no Suriname e Guiana Francesa e ainda da drenagem do rio Negro na Amazônia, é reconhecida pela ampla largura da cabeça e boca e pela nadadeira anal modificada em machos com extremidade pontiaguda. Tatia dunni, do alto Amazonas, é reconhecida pela cabeça estreita, pelo processo pós-cleitral longo em alguns espécimens, e pela coloração do corpo com manchas irregulares ou faixas claras. Tatia galaxias, endêmica da bacia do rio Orinoco, é distinguida pelos grandes olhos e focinho curto. Tatia gyrina, com ocorrência pelo alto e médio Amazonas, e pelos rios do norte do Suriname, possui mesetmóide reduzido, mandíbula levemente prognata, segunda placa nucal com bordo lateral estreito, terceira placa nucal reduzida, pré-vomer pequeno, reduzido número de costelas, pequeno número de vértebras e dimorfismo sexual onde a papila genital masculina é entumescida. Tatia intermedia é registrada para o médio e baixo rio Amazonas, rio Tocantins e ainda para drenagens costeiras na Guiana, Suriname, Guiana Francesa e leste do Pará no Brasil. É distinguida pelo processo do pós-cleitro curto, olhos pequenos e focinho longo.

A riqueza hidrológica no Extremo Sul da Bahia é contrastante em relação à ainda pouco conhecida fauna de peixes. Impressiona a presença de diversas espécies ainda não descritas. O presente estudo é parte de uma série que pretende avaliar os sistemas hídricos do Extremo Sul da Bahia do ponto de vista da ictiofauna nas diversas bacias. Aqui são investigados os peixes da bacia do Rio Peruípe, um sistema ímpar de drenagem fluvial, com um amplo delta. Foram averiguados onze pontos georreferenciados em rios e riachos daquele sistema de drenagem. O uso de metodologia para coleta de dados ambientais e de peixes possibilitou descrever cada ambiente coletado bem como documentar a composição taxonômica da ictiofauna. São fornecidas ilustrações das localidades amostrais e de espécimes representativos de algumas das espécies coletadas, exibindo sua coloração em vida. No total foram verificadas 26 espécies pertencentes a 12 famílias em 6 ordens. Das espécies coletadas Trichomycterus pradensis Sarmento-Soares et al. (2005) e Microglanis pataxo Sarmento-Soares et al. (2006) foram recentemente descritas como novas. Aproximadamente 48,7% do total de peixes na bacia pertencem à ordem Siluriformes, 38,5% a Characiformes, 34,6% a Perciformes, 11,5% a Cyprinodontiformes, 7,7% a Gymnotiformes, 3,8% a Synbranchiformes e 3,8% a Pleuronectiformes. As espécies mais freqüentes em termos de constância de ocorrência foram Geophagus brasiliensis (presente em 82% das coletas), Hoplias malabaricus (64%), Astyanax cf. rivularis (55%), Poecilia vivipara (55%), Astyanax cf. lacustris (45%) e Hyphessobrycon bifasciatus (45%). A partir das informações de captura dos peixes em cada ponto amostrado da bacia determinou-se a riqueza, a diversidade, a equitabilidade e a dominância. As condições ambientais nos trechos da bacia são apontadas como influências na ocorrência e distribuição das espécies. A predominância de peixes de pequeno porte, não ultrapassando 150 mm CP, é associada a um acentuado endemismo regional. Hydrological richness on extreme southern Bahia contrasts with the poorly known freshwater fish fauna. It is surprising the presence of several species still undescribed. The present study is the first contribution dealing with the fish fauna of the local river basins. We herein investigate fish fauna of Rio Peruípe basin, a remarkably freshwater drainage, with a wide estuary. Eleven localities, geo-referred, were evaluated in streams and rivulets along that freshwater drainage. The employment of methodology for collecting the environmental data and the fishes made possible the description of each locality sampled, as well as the documentation of the taxonomic composition of the fish fauna. Illustrations of the collecting localities and of individuals of some representative species, in live coloration, are provided. There were found 26 species belonging to 12 families in 6 orders. Within the species sampled Trichomycterus pradensis Sarmento-Soares et al. (2005) and Microglanis pataxo Sarmento Soares et al. (2006) were recently described as new. About 48.7% of total amount of fishes caught belong to the order Siluriformes, 38.5% to Characiformes, 34.6% to Perciformes, 11.5% to Cyprinodontiformes, 7.7% to Gymnotiformes, 3.8% to Synbranchiformes, and 3.8% to Pleuronectiformes. The most frequent species in terms of constancy of occurrence were Geophagus brasiliensis (present in 82% of sampled localities), Hoplias malabaricus (64%), Astyanax cf. rivularis (55%), Poecilia vivipara (55%), Astyanax cf. lacustris (45%) and Hyphessobrycon bifasciatus (45%). Based on information about the fishes caught in each collecting locality there were estimated the richness, the diversity, the equitability and the dominance. The potential loss of microenvironments in some portions of rivers is pointed as a factor influencing on the occurrence and distribution of some species. The dominance of small sized fishes, not exceeding 150 mm CP, is associated to a high regional endemism.

Characidium helmeri , a species of the family Crenuchidae apparently endemic to rivers draining the extreme south of Bahia, Brazil, is described. The new species is easily distinguished from congeners by having dark, vertically elongated, irregular spots or dashes on flanks, usually more evident over midlateral stripe and/or ventral half of body, where it may present a somewhat curved or zigzag-shape. Characidium helmeri can be further distinguished from most congeners by having lateral line reduced to 13–22 pored scales, adipose fin absent, isthmus naked on its anteriormost portion, 14 scales around caudal peduncle, 4 scales above lateral line and 4 below, two series of dentary teeth, supraorbital absent or extremely reduced, and basicaudal black spot well defined. The occurrence of reductive characters in Characidium is briefly discussed.

A new trichomycterid catfish of the genus Ituglanis is described from the rio Palmares, a tributary of the rio Cahy in southeast Bahia State, Brazil. Ituglanis cahyensis is distinguished from all other congeners through a combination of characters, as the supraorbital laterosensory canal branch with pores s3 and s6 present, the low count of branched pectoral fin rays, and low number of paired ribs. It is further distinguished in proportional measurements, such as elongate nasal, maxillary, and rictal barbels, and small eye diameter. É descrito um novo trichomycterídeo do gênero Ituglanis, capturado no rio Palmares, um tributário do rio Cahy, na costa sudeste do estado da Bahia, Brasil. Ituglanis cahyensis distingue-se das demais espécies congêneres por uma combinação de caracteres, como o canal laterosensorial supraorbital com os poros s3 e s6 presentes, um pequeno número de raios ramificados nas nadadeiras peitorais, e um pequeno número de costelas. Distingue-se ainda quanto a proporções morfométricas, como os barbilhões nasal, maxilar e rictal alongados, e o pequeno diâmetro ocular.

The hydrographic basin of southeastern Espírito Santo comprises the systems of Rio Novo, Rio Benevente and small river basins of the Guarapari. The present study is part of a series of studies on the fish fauna of river basins in Espírito Santo State. Fourty-five geo-referrerenced points in rivers and rivulets of the region were evaluated, 13 in the Rio Novo basin, 23 in the Rio Benevente basin and nine in small river basins in the municipalities of Anchieta, Guarapari, and Vila Velha. The environment and fish fauna were documented at every point, reporting a total of 110 species (54 marine), belonging to 46 families and 17 orders, most of which are Perciformes (42 species). With the exception of marine species, most of the fishes belong to the orders Characiformes and Siluriformes, with 16 species each. The Atlantic forest along the rivers of southeastern Espírito Santo region is composed of ombrophylous forest, pluvial submontane forest and pioneer formations (swamps, coastal sand dunes, and mangroves). The wetlands and coastal lake environments in the area are submitted to intense disturbances, and in this sense, the conservation units are extremely important for their preservation. The regional endemism of freshwater fishes is commented on, as well as the presence of potentially new species in the study area.

- Abstract
The hydrographic basins of northern Espírito Santo comprises the systems of Itaúnas and São Mateus rivers. The present work is part of a series of studies on the fish fauna along Espírito Santo’s river basins. Forty-nine geo-referred points in rivers and rivulets of the area were evaluated, 20 in the Itaúnas basin and 28 in São Mateus basin. The environment and the taxonomic composition of the fish fauna were documented at every point, reporting a total of 83 species, including 47 freshwater species and 36 marine, belonging to 35 families and 11 orders. Among the freshwater fish species, the Siluriformes predominated, with 20 species, followed by the Characiformes, with 17 species. The Atlantic forest of northern Espírito Santo, known as “floresta de tabuleiros”, was originally composed of ombrophylous forest as well as swamps, coastal sand dunes, and mangroves. With the suppression of native forests, the region has suffered from desertification, and environmental conditions are similar to the northeastern semiarid region, where the run-off waters are dispersed or intermittent. The loss of environmental quality along river valleys is associated with the need to reestablish riverine aquatic conditions. Exotic species and risks of introductions need further studies in these areas. Rare or endangered species whose distributional range has diminished in response to environmental changes may function as biological indicators. Potentially new species are identified, and regional endemism and distribution patterns for freshwater fishes are discussed.

Parotocinclus arandai, new species of the hypoptopomatine catfish, is described from small creeks in the upper rios Jucuruçu and Buranhém basins, at the border of Brazilian States of Bahia and Minas Gerais. Parotocinclus arandai is distinguished from all congeners from the Atlantic coastal basins of southeastern and eastern Brazil, except Parotocinclus bahiensis, by having the branched rays and interradial membranes of the pectoral and pelvic fins unpigmented in ventral view. The new species is distinguished from most Parotocinclus species, by having a small eye, 14.8-19.3 mm HL (except P. maculicauda and P. planicauda) and by the presence of a tuft of hypertrophied odontodes on the supraoccipital (except P. cristatus and P. cesarpintoi). Parotocinclus arandai is further distinguished by having an abdomen extensively naked, with a mosaic of few rounded platelets of irregular size and distributed over the pre-anal region (except P. bahiensis, P. minutus, P. spilosoma, P. cearensis, P. cesarpintoi and P. prata). A detailed comparison with congeners on eastern Brazil hydrographical region is provided, and information on the species habitat is given.

Glanidium botocudo, new species, is described from the tributaries to the upper rio Doce and Mucuri, eastern Minas Gerais State, Brazil. It represents the northernmost record of a centromochlin catfish from the coastal rivers of the Northeastern Atlantic Forest. Glanidium botocudo is readily distinguished from its congeners, except Glanidium albescens, by the whitish grey body coloration with evenly spaced small dark brown dots. The new species has a long sharpened ventral process on the urohyal, an uncommon condition among congeners, and the lowest vertebral count among the large-sized Glanidium, 36-37. It differs from Glanidium albescens by proportional measurements and higher number of ribs. Glanidium botocudo and Glanidium albescens are probably sister species, exhibiting similar morphological features and a complimentary distribution pattern, associated to an allopatric distribution pattern. Glanidium bockmanni is transferred to the genus Centromochlus. Glanidium botocudo, especie nova, e descrita para tributarios do alto rio Doce e rio Mucuri, leste de Minas Gerais, Brasil. Representa o registro mais ao norte de um bagre centromoclineo nos rios do Nordeste da Mata Atlântica. Glanidium botocudo e prontamente distinguido de todos seus congeneres, exceto Glanidium albescens, pelo colorido cinza-esbranquicado do corpo com maculas castanho-escuras regularmente espacadas. A especie nova apresenta processo ventral do uro-hial longo e afilado, uma condicao incomum entre os congeneres, e ainda a menor contagem vertebral entre os Glanidium de grande porte, 36-37. Diferencia-se de Glanidium albescens por proporcoes corporais e maior numero de costelas. Glanidium botocudo e Glanidium albescens sao possivelmente especies irmas, apresentando caracteristicas morfologicas similares e padroes de distribuicao complementar, associados a um padrao de distribuicao alopatrica. Glanidium bockmanni e transferido para o genero Centromochlus.
