“…The animals are cream-colored beige or light brown and the snout exhibited a broad beige ring circling the rostral and nasal shields, as well as half of the pre-oculars (Figures 2A and 2B). This description is consistent with the holotype, as well as the physiognomy of the type locality: dune areas on the banks of the São Francisco River (Rodrigues and Juncá 2002). However, this new locality forms part of the Atlantic Forest Biome rather than of the Caatinga area originally described.…”

This study presents the first records of Typhlops amoipira to the Brazilian Atlantic Forest biome and expands its geographic distribution up to 1033 km northward of the type locality. The record for Piaçabuçu, state of Alagoas, can be justified by contact with the dunes of the São Francisco River. However, although dunes and restinga are present in other locations such as Nísia Floresta and Atlantic Forest areas in the municipalities of Coruripe and São José da Laje, Alagoas, they do not come into contact with dunes along the São Francisco River.

Pfenninger, M. (2011). Integrative inventory of Bolivia's lowland anurans reveals hidden diversity. -Zoologica Scripta, 40, 567-583. We conducted an integrative species inventory and re-evaluated the taxonomic status of anuran populations from lowland Bolivia that we putatively ordered to 59 a priori species. The analyses of own and published data of mtDNA (16S), bioacoustics, and adult and tadpole morphology, however, revealed a total number of 69 divergent lineages. With the data at hand, the taxonomic assignment of only 27 from 69 lineages (39.1%) to nominal species was supported, the assignment of nine lineages (14.5% of 69) was attributed to incertae sedis, and another 33 divergent lineages (47.8%) could not yet be assigned to any species. Of those lineages, 16 were confirmed as divergent to other species by at least two of the following lines of evidence: high genetic divergence, strong differences in advertisement calls, morphology or ecology. These 'confirmed genealogical lineages' are suggested to belong to good species following standards of divergence of the group under study, many of them probably being candidates for formal descriptions. Another 17 lineages were considered as 'unconfirmed genealogical lineages' showing significant difference to all other described species only in one line of evidence. Within 6 of our 69 revealed lineages, we detected deep conspecific lineages. Some species in this study showed remarkable intraspecific call variation not congruent with genetic divergence. Our results suggest that many Bolivian anuran species that are assigned to supposedly 'widespread' South American species apparently belong to previously unrecognized lineages with supposedly smaller distribution areas. Our data on a regional scale urge for an integrative taxonomic review of these and other widespread lowland Neotropical anuran species, as many of them may actually represent species complexes. However, a complete inventory of Neotropical amphibians apparently is a far more complex challenge than previously thought, and only cooperative, supraregional and cross-country approaches will reveal the actual amphibian diversity in the Neotropics. We postulate that Bolivia's lowlands can be assessed as a region joining distinct regional faunal diversity and thus deserve reinforced conservation and research efforts to fulfil its unique situation as climatic and biogeographic transition zone.

“…Considering that many species and genera of Gymnophthalmidae are still unknown beyond their original descriptions, and that new genera are still being discovered on a regular basis (at least five new genera have been recently described, see Rodrigues & Juncá, 2002), we are still far from having a broad survey of morphological characters for a significant number of taxa. As a comprehensive assembling of morphological data for all genera will require a huge effort, we suggest that the presentation of morphological information for selected groups, targeting specific questions that can be addressed by combining molecular and morphological data, will be useful to refine published hypotheses and extend our knowledge of the evolution of this clade on an incremental basis.…”

A new genus and species of a short limbed and slightly elongate gymnophthalmid lizard is described from the Atlantic rain forests of north-eastern Brazil. The new genus is also characterized by short and stout pentadactyl limbs, presence of prefrontals, absence of frontoparietals, distinctive ear opening and eyelid, two pairs of genials, a distinct collar, smooth, quadrangular, dorsal scales, quadrangular ventrals, fused postfrontal and postorbital bones, and two pairs of sternal ribs. The geographical distribution of the new taxon extends from the state of Rio Grande do Norte to the northern bank of the Rio São Francisco in the state of Alagoas. All specimens were obtained in leaf litter, an observation which agrees with the fossorial habits suggested by the body shape and massive aspect of the head of this species. A phylogenetic analysis based on external morphology, osteology, and molecular data recovered the new lizard as the sister genus to Anotosaura , and Colobosauroides as the sister group to these two.
