Contribuição ao Conhecimento da Distribuição Geográfica do Tatu-de-Rabo-Mole-Grande Cabassous tatouay no Brasil: Revisão, Status e Comentários sobre a Espécie

The greater naked-tailed armadillo Cabassous tatouay is one of the least-known armadillo species. Field records are rare, if not controversial, and only few specimens exist in scientific collections in Brazil. This species is listed in the Brazilian Red List of Threatened Species as well as in six official Brazilian state Red Lists. Fieldwork was performed between 2005 and 2008 to monitor wildlife in the central-western region of São Paulo State. Cabassous tatouay was registered in three opportunities, in the municipalities of Agudos, Borebi and Avare, and ecological and morphometrical data were registered. Although this species tolerates altered habitats, the scarce field records may be related to its habits and have led to the lack of basic information on greater naked-tailed armadillos. This communication provides important ecological and biogeographical information about C. tatouay.

A noteworthy new species of Peritassa (Celastraceae, Hippocrateoideae) from Amazonian Brazil

The new species Peritassa Manaoara, Lombardi differs from other species in Peritassa Miers by its unique 3-lobed stigma. The inclusion of this new taxon in Peritassa was based on the characteristics of non-confluent anther locules and the disc free from the ovary wall, which distinguishes this species from Tontelea Aublet, the Only other genus of Neotropical Hippoerateoideae species with a 3-lobed stigma and tubular nectariferous disc.

Three new South American species of Salacia with fasciculate inflorescences (Celastraceae, Hippocrateoideae)

Three new fasciculate flowered species of Salacia L. (Celastraceae, Hippocrateoideae) from the Amazon basin are described: S. acevedoi Lombardi is distinguished by its small flowers, stamens with short filaments, disc connate to ovary, and size of fruits; S. negrensis Lombardi differs by its habit, characteristics and shape of leaves, flower diameter, features and size of stamens, and number of ovules: and S. odorata Lombardi is characterized by its long pedicels, conical flower buds, strongly adherent petals. and flat disc with fimbriate outer border.

Natural History of the Lutz's Frog Cycloramphus lutzorum Heyer, 1983 (Anura: Cycloramphidae) in the Brazilian Atlantic Forest: Description of the Advertisement Call, Tadpole, and Karyotype

We describe the advertisement call, tadpole, karyotype, and additional information on the natural history of Cycloramphus lutzorum from southern Brazil. Sonograms were generated from digitally recorded calls. Tadpoles were collected in the field for description in the lab, and an adult was collected for karyotyping. Data on seasonal activity were gathered monthly from November 2005 to November 2007. All tadpoles (N = 21), juveniles (N = 18), and adults (N = 52) were found exclusively in streams. Reproduction, as identified by calling frogs, occurred from July through November. Frogs call all day long, but mostly at dusk, from rock crevices inside the stream edges near the splash zone. The call is short and loud, with 11 pulsed notes, of 491-641 ms, with a dominant frequency of 0.98-1.39 kHz. We describe the exotrophic and semiterrestrial tadpoles, always found in constantly humid vertical rock walls in the stream. Tadpoles of C. lutzorum are recognized by differences in labial tooth row formula, eye diameter, body shape, position of nares, and development of tail. Like congeneric species, the karyotype of C. lutzorum comprises 26 metacentric and submetacentric chromosomes. Cycloramphus lutzorum is restricted to and adapted for living in fast flowing streams, many of which are threatened by deforestation, pollution, and habitat loss. Therefore, we recommend the status of C. lutzorum be changed from its current "Data Deficient" to "Near Threatened (NT)" in the IUCN species red list.

A new species of Cordia (Cordiaceae, Boraginales) from Brazil

A new species from Brazil, Cordia pilosa M. Stapf & Taroda (Cordiaceae), is described from northeastern Brazil. Illustrations and data on habitat, distribution, and phenology are provided. The new species belongs to Cordia sect. Superbiflorae Taroda, and it is distinguished from similar species in section Superbiflorae by its compact inflorescences and the pilose indument on the twigs, leaves, and inflorescence axes. © 2010 Missouri Botanical Garden.

From widespread to microendemic: Molecular and acoustic analyses show that Ischnocnema guentheri (Amphibia: Brachycephalidae) is endemic to Rio de Janeiro, Brazil

Many species of tropical amphibians are restricted to very small ranges, and this microendemism coupled with ongoing habitat loss and susceptibility to emerging pathogens imperils the long-term persistence of these species. Incomplete taxonomic and distributional knowledge may obscure conservation assessment, particularly in putatively widespread species that are typically considered to be of Least Concern in Red List assessments, but that in fact may constitute complexes of partly microendemic species. Such is the case in the Steindachner's Robber Frog, Ischnocnema guentheri which, together with the recently recognized Ischnocnema henselii, is thought to occupy most of the Brazilian Atlantic Forest. To test whether these taxa may constitute a species complex of range-restricted and thus potentially threatened species, we analyzed 160 samples of I. guentheri and/or I. henselii for two molecular markers, 16S rRNA (16S) and recombination activation gene 1 (RAG1). To verify the monophyly of the complex, closely related species were also included in the 16S analysis. Congruent evidence from the molecular data and from analyses of advertisement calls support the existence of six distinct species within the complex: I. guentheri and I. henselii as well as four candidate new species. The lineages are distributed as a mosaic in the Atlantic Forest and are sympatric at some localities without indication of admixture. Their phylogeographical pattern partially agrees with paleo-models for the Atlantic Forest, but also suggests the existence of micro-refugia in less stable areas. I. guentheri, previously considered to be widespread, was found only in its type locality, a reserve within the urban area of Rio de Janeiro city. Although none of the species studied appears highly threatened with extinction, we recommend their IUCN threat status to be re-evaluated carefully for the next comprehensive update of the Red List of Brazil's amphibians. © 2013 Springer Science+Business Media Dordrecht.
