Glanidium botocudo, a new species from the rio Doce and rio Mucuri, Minas Gerais, Brazil (Siluriformes: Auchenipteridae) with comments on taxonomic position of Glanidium bockmanniSarmento-Soares &amp;amp; Buckup
Provedor de dados: 83
Autores: Sarmento-Soares,Luisa Maria; Martins-Pinheiro,Ronaldo Fernando.
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 albescensby proportional measurements and higher number of ribs. Glanidium botocudo and Glanidium albescens are probably sister...

A systematic revision of Tatia (Siluriformes: Auchenipteridae: Centromochlinae)
Provedor de dados: 83
Autores: Sarmento-Soares,Luisa Maria; Martins-Pinheiro,Ronaldo Fernando.
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...

Parotocinclus arandai, a new species of hypoptopomatine catfish (Siluriformes: Loricariidae) from the upper rios Jucuruçu and Buranhém, States of Bahia and Minas Gerais, Brazil
Provedor de dados: 83
Autores: Sarmento-Soares,Luisa Maria; Lehmann A.,Pablo; Martins-Pinheiro,Ronaldo Fernando.
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...

A fauna de peixes na bacia do Rio Peruípe, extremo Sul da Bahia
Provedor de dados: 49
Autores: Sarmento-Soares,Luisa Maria; Mazzoni,Rosana; Martins-Pinheiro,Ronaldo Fernando.
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...
