Revision of the genus Pseudotocinclus (Siluriformes: Loricariidae: Hypoptopomatinae), with descriptions of two new species

O gênero Pseudotocinclus é revisado e duas novas espécies são descritas: Pseudotocinclus juquiae da bacia do rio Ribeira de Iguape e Pseudotocinclus parahybae da bacia do rio Paraíba do Sul. A presença de uma pequena área nua na ponta do focinho distingue P. tietensis de P. parahybae e P. juquiae, que apresentam a ponta do focinho coberta por pequenas placas. Além disso, P. tietensis tem quatro bandas transversas marrom-escuras na região dorsal do corpo, fundidas com uma barra mediana lateral, ao invés de três bandas, como nas demais espécies. Pseudotocinclus juquiae distingue-se de suas congêneres pela presença de um anel orbital muito proeminente e conspícuo não observado em P. tietensis ou P. parahybae. As três espécies também diferem quanto a seus dados morfométricos e merísticos. São apresentados comentários a respeito das conexões pretéritas das bacias dos rios Ribeira de Iguape, alto Tietê e Paraíba do Sul.

Characidium xanthopterum (Ostariophysi: Characiformes: Crenuchidae): a new species from the Central Brazilian Plateau

Characidium xanthopterum é descrita de tributários das bacias do alto Paraná e do alto Tocantins, no Planalto Central do Brasil, Estado de Goiás, Brasil. Entre as congêneres, a nova espécie é diagnosticada pela ausência de barras escuras nas porções laterais do corpo em exemplares adultos, e pela presença de todas as nadadeiras fortemente amareladas, sem marcas ou manchas. Exemplares menores de 32 mm CP apresentam barras escuras no corpo. Estas barras desaparecem com o crescimento entre 32 e 35 mm CP, e estão sempre ausentes em indivíduos maiores do que 35 mm CP.

Two new genera and five new species of the feather mite subfamily Proctophyllodinae (Astigmata : Proctophyllodidae) from suboscine birds in Brazil

Two new genera and five new species of feather mites of the family Proctophyllodidae are described from passerine birds from Brazil: Tyranniphyllodes pitangi gen. n., sp. n. from Pitangus sulphuratus (Tyrannidae); Atrichophyllodes delalandi gen. n., sp. n. from Corythopis delalandi (Tyrannidae); A. mentalis gen. n., sp. n. from Dysithamnus mentalis (Thamnophilidae); Anisophyllodes candango sp. n. from Elaenia chiriquensis (Tyrannidae); and Platyacarus sittasomi sp. n. from Sittasomus griseicapillus (Dendrocolaptidae). The discovery of these taxa might give data for a better understanding of the evolution of the family Proctophyllodidae in general and the dispersion of these mites on passerines in South America in paricular.

New species of Bokermannohyla (Anura, Hylidae) from Central Bahia, Brazil

A new species of treefrog closely related to Bokermannohyla alvarengai is described from Chapada Diamantina centrally located in the State of Bahia, Brazil. In comparison to B. alvarengai, the new species is smaller in size, with less developed forearm and prepollexes, and smaller tympani. We describe the tadpole, advertisement call and provide information on its natural history. We propose the B. alvarengai group to accommodate this species and the new species described here.

A new species of the Bokermannohyla pseudopseudis group from central Bahia, Brazil (Amphibia, Hylidae)

A new species of treefrog is described from Chapada Diamantina in the central State of Bahia, Brazil. The new species is a member of the Bokermannohyla pseudopseudis group, characterized by its small to medium size, head as long as wide, snout short, rounded in dorsal view and nearly truncate in lateral view, eyes and tympanum large, and forearm and prepollex well developed. The new species can be distinguished from the other species of the B. pseudopseudis group by its voice and the shape of its head and snout. it is smaller than B. saxicola and B. pseudopseudis, and has a less developed forearm and prepollex than B. ibitiguara males. The tadpole and vocalizations are described and information on natural history is provided.

A NEW SPECIES OF TAPINURUS FROM THE CAATINGA OF PIAUI, NORTHEASTERN BRAZIL (SQUAMATA, TROPIDURIDAE)

Tapinurus helenae sp. nov. is described from northeastern Brazil. The species is characterized by a dorsoventrally depressed body three bluish-white longitudinal stripes, the middorsal one interrupted at the scapular area, and an ochre colored dorsum that is lacking in larger males. Tapinurus helenae is easily distinguished from the other two known species, T. semitaeniatus and T. pinima, by its interrupted middorsal stripe. The new species inhabits calcareous massifs and sandstones in forested caatinga at the Toca de Cima dos Pilao, Sao Raimundo Nonato, Piaui, northeastern Brazil.

NEW SPECIES OF CROSSODACTYLUS (ANURA, LEPTODACTYLIDAE) FROM THE ATLANTIC RAIN-FOREST OF SOUTHEASTERN BRAZIL

A new species of leptodactylid frog, Crossodactylus caramaschii, is described from the southern part of the state of São Paulo, southeastern Brazil. The new species, a member of the Crossodactylus gaudichaudii group, is characterized by having a short snout, a distinct and straight canthus rostralis, and reticulated belly.
