“…Sequence divergences among different haplotypes within and among populations from this study and from Rodrigues et al 2014 (GenBank 234-bp (Bandelt et al 1999), to depict the relationships among the 11 haplotypes of E. perditus and the eight of E. bilineatus (this study and Rodrigues et al 2014).…”

“…Enyalius (Leiosauridae) comprises at least 10 endemic South American taxa; systematic relationships among these taxa are challenging given the variation in their color patterns (Rodrigues et al 2014). The species are widely distributed through the Atlantic Forest; one species is found in the Amazon, and others occur in remote locations of the Caatinga and Cerrado gallery forests (Etheridge 1969, Vanzolini 1973, Jackson 1978, Ávila-Pires 1995.…”

“…Enyalius bilineatus inhabits regions of the Atlantic Forest in the states of Minas Gerais, Rio de Janeiro and Espírito Santo and areas of Cerrado and Caatinga habitats in Minas Gerais (Etheridge 1969, Jackson 1978, Zamprogno et al 2001, Bertolotto et al 2002, Colli 2003, Sousa et al 2010. Enyalius bilineatus is sympatric with E. perditus at high elevations in the Atlantic Forest (Barreto-Lima 2012, Rodrigues et al 2014).…”

“…The few studies that examine the distribution (Barreto-Lima 2012) and evolutionary history of these species (Bertolotto 2006, Rodrigues et al 2014 emphasize the need to increase the number of localities sampled to better understand the relationship between the levels of genetic diversities, genetic structure, and phylogeny of the genus. These data will reveal cryptic diversity and inform effective con servation actions.…”

“…Based on an analysis of chromosomes, and mitochondrial and nuclear markers from Enyalius lineages of E. bilineatus from Minas Gerais; the author suggested that E. bilineatus represented two different species. In a more inclusive biogeographic study, Rodrigues et al (2014) examined the 10 recognized species of Enyalius from 51 Brazilian localities; they reported high diversity and several taxonomic problems. The authors found E. perditus to be paraphyletic and E. bilineatus to contain cryptic diversity expressed as two coherent, divergent geographic clades.…”

Genetic diversity and structure of two species of Enyalius (Squamata: Leiosauridae) from neotropical biodiversity hotspots. Enyalius, a lizard genus endemic to South America, is mostly distributed in the remains of the Atlantic Forest and in the Cerrado. The structure within and among populations of Enyalius. The genetic diversity and structure of populations of E. bilineatus (N = 20) and E. perditus (N = 28) are examined using a 234-bp fragment of the cytochrome b gene and compared with the sequences reported in other published data. Nineteen distinct haplotypes (eleven for E. perditus and eight for E. bilineatus diversities are highly similar for both species (0.684 for E. perditus and 0.647 for E. bilineatus). The genetic distance between the two species is 20.3% and the distance within species is 2.0% and 5.6% for E. perditus and E. bilineatus, respectively. Our data suggest that populations of E. bilineatus are genetically divergent and may reveal cryptic diversity.Enyalius from Neotropical biodiversity hotspots. These data facilitate a better understanding of both 100 Phyllomedusa -14(2), December 2015 within and among population variation, and highlight the distribution of genetic lineages of an endemic and poorly studied genus.Keywords: Atlantic Forest, Cerrado, cytochrome b (cyt b), Enyalius bilineatus, Enyalius perditus.Resumo Diversidade e estrutura genética de duas espécies de Enyalius (Squamata: Leiosauridae) em hotspots neotropicais de biodiversidade. Os lagartos do gênero Enyalius são endêmicos da América do Sul, sendo predominantemente encontrados no Cerrado e em fragmentos da Floresta Atlântica. Este é um gênero pouco estudado, e não foram encontrados dados relacionados à diversidade e à estrutura genética das espécies do gênero. Neste trabalho, investigamos a diversidade genética de populações de E. bilineatus (N = 20) e E. perditus (N = 28), usando um fragmento de 234-pb do citocromo b, e comparamos as sequências geradas com outras publicadas. Dezenove haplótipos distintos foram encontrados (11 de E. perditus e oito de E. bilineatus), sendo oito deles novos registros. Os valores de diversidade haplotípica foram muito similares para as duas espécies (0.684 para E. perditus e 0.647 para E. bilineatus). A distância genética entre as duas espécies foi de 20.3%, E. perditus e 5.6% para E. bilineatus. Nossos dados sugerem que as populações de E. bilineatus são altamente divergentes e que a espécie deve apresentar diversidade críptica. Este é o primeiro estudo medindo a diversidade genética de espécies do gênero Enyalius oriundas de regiões consideradas hotspots da biodiversidade neotropical e apresenta dados relevantes para um melhor entendimento das relações inter e intrapopulacionais, assim como a distribuição das linhagens genéticas desse gênero endêmico.

The Amazonia and the Atlantic Forest, separated by the diagonal of open formations, are two ecoregions that comprise the most diverse tropical forests in the world. The Sphaenorhynchini tribe is among the few tribes of anurans that occur in both rainforests, and their historical biogeographic have never been proposed. In this study, we infer a dated phylogeny for the species of the Sphaenorhynchini and we reconstructed the biogeographic history describing the diversification chronology, and possible patterns of dispersion and vicariance, providing information about how orogeny, forest dynamics and allopatric speciation affected their evolution in South America. We provided a dated phylogeny and biogeography study for the Sphaenorhynchini tribe using mitochondrial and nuclear genes. We analyzed 41 samples to estimate the ancestral areas using biogeographical analysis based on the estimated divergence times and the current geographical ranges of the species of Sphaenorhynchini. We recovered three characteristic clades that we recognize as groups of species ( S . lacteus , S . planicola , and S . platycephalus groups), with S . carneus and G . pauloalvini being the sister taxa of all other species from the tribe. We found that the diversification of the tribe lineages coincided with the main climatic and geological factors that shaped the Neotropical landscape during the Cenozoic. The most recent common ancestor of the Sphaenorhynchini species emerged in the North of the Atlantic Forest and migrated to the Amazonia in different dispersion events that occurred during the connections between these ecoregions. This is the first large‐scale study to include an almost complete calibrated phylogeny of Sphaenorhynchini, presenting important information about the evolution and diversification of the tribe. Overall, we suggest that biogeographic historical of Sphaenorhynchini have resulted from a combination of repeated range expansion and contraction cycles concurrent with climate fluctuations and dispersal events between the Atlantic Forest and Amazonia.
