Abstract:
We perform a review of the Erythrolamprus reginae species group and putative related taxa (E. dorsocorallinus, E. zweifeli, and E. oligolepis), based on external morphology and hemipenial characters. We infer species boundaries among taxa traditionally associated with this group, recognizing two nominal subspecies (Erythrolamprus reginae reginae and E. r. macrosomus) in the species level. We propose the synonymy of E. r. semilineatus with E. reginae and recognize the validity of the related taxa, such as: E. dorsocorallinus, E. zweifeli, and E. oligolepis. In addition, two specimens occurring in the state Amapá, Brazil, are herein described as a new species. Therefore, we provide an identification key for the species of the group and discuss some of the combination of morphological features useful to delimitate the species of this group, in comparison with other representatives of the genus Erythrolamprus.

Abstract:
The genus Erythrolamprus Boie (1826) comprises six species of Central and South American false coral snakes (Peters & Orejas-Miranda 1970; Zaher 1999; Curcio et al. 2009). It is traditionally allocated in the tribe Xenodontini (subfamily Xenodontinae), along with the genera Liophis, Lystrophis, Umbrivaga, Waglerophis and Xenodon (sensu Dixon 1980; Cadle 1984; Myers 1986; Ferrarezzi 1994; Zaher 1999). Although Xenodontini is supported by morphological and molecular evidence, phylogenetic relationships and classification within the tribe have been the subject of recent debate. Molecular phylogenetic studies have recovered clades with Erythrolamprus nested within some representatives of the genus Liophis (Vidal et al. 2000; Zaher et al. 2009), partly corroborating previous hypotheses based on morphology (e.g. Dixon 1980).

Abstract:
The systematics of South American Xenodontinae snakes has experienced large changes and improvements as a result of recent studies employing molecular data. Herein we assess the status of the rare Peruvian snake species, Erythrolamprus problematicus (Dipsadidae, Xenodontinae, Xenodontini), previously known from a single specimen collected in 1950. Based on new morphological and molecular data from a second specimen that we collected, we confirmed the presence of a crease in the rostral scale, mentioned in the original description (a unique trait among the Xenodontini), and recovered E. problematicus as the sister-taxon of all other Xenodontini, instead of nested among the current Erythrolamprus. Therefore, our phylogenetic results justify the erection of a new genus to accommodate the species.

Abstract:
AbstractThe Caribbean Islands are a biodiversity hotspot where anthropogenic disturbances have had a significant impact, causing population declines and extinction of endemic species. The ground snake Erythrolamprus cursor is a dipsadid endemic to Martinique; it is categorized as Critically Endangered on the IUCN Red List and is known only from museum specimens. The snake was common on Martinique during the 18th and 19th centuries but there have been no reliable sightings since 1968, suggesting it may have gone extinct, probably as a result of the introduction of the small Indian mongoose Herpestes javanicus auropunctatus. However, the islet known as Diamond Rock, south-west of Martinique, is mongoose-free and the last reported sighting of E. cursor there was in 1968. The islet was last occupied during the Napoleonic Empire (the early 19th century), is now completely protected, and is difficult to access (it spans 5.8 ha, with a maximum elevation of 175 m). We conducted the first extensive survey of the islet, over 10 days, to clarifty the status of E. cursor. Our study revealed that unique conditions exist on Diamond Rock (i.e. aridity and a distinct potential prey community) and that E. cursor would have had to modify its ecology to persist on the islet. Although the rugged terrain of Diamond Rock makes it difficult to explore, it is probable that E. cursor is now extinct.

Abstract:
ABSTRACT The snakes Erythrolamprus jaegeri jaegeri and Erythrolamprus poecilogyrus sublineatus are sympatric and syntopic in the coastal region of southern Brazil. Herein, we analyzed the diet composition to evaluate the niche breadth and the prey selection by both species. We examined 192 specimens, and analysis of stomach contents revealed that both species predominantly consume anurans. However, the diet of E. j. jaegeri consists mainly of fish and amphibians, whereas that of E. p. sublineatus is broader, including fish, amphibians, reptiles and mammals. The Standardized Levins Index presented lower values for E. j. jaegeri (BA = 0.17) than for E. p. sublineatus (BA = 0.61), evidencing specialist and generalist strategies for each species, respectively. Regarding prey selection, E. p. sublineatus presented a larger snout-vent length, head, mouth and lower jaw than E. j. jaegeri and fed on larger prey. In addition, positive correlations between the size and weight of predators and prey were confirmed in both species. The results show the development of different mechanisms for co-occurrence of the two species, such as prey selection by size, such that the size of the predator is related to the size of their prey, or by developing different strategies to decrease niche overlap between species.

Abstract:
Abstract Erythrolamprus poecilogyrus sublineatus (Cope, 1860), is a species widely distributed in the Pampa Domain, occurring in Rio Grande do Sul, Argentina and Uruguay, mainlyin the pampa region. In the coastal region of southern Brazil this is serpent is considered one of the most abundant. The purpose of the present study is to describe the techniques of sperm evaluation in vitro for E. poecilogyrus sublineatus in the coastal plain of Rio Grande do Sul, Brazil. After laparatomy the efferent vases were collected and the semen was diluted in 1ml Beltsville Thawing Solution. The characteristics of motility, membrane integrity, mitochondria, acrosome, DNA, cell viability and cellular functionality were evaluated. Fluorescent probes were used for the evaluation of sperm structure in epifluorescence microscope. With the techniques described, it was possible to identify intact and injured cells, enabling the determination of cell characteristics for the spring season (October and November). It was observed in the analyses that 80% of sperm cells were mobile and that 84.1 ± 8.0% of sperm membranes were intact. The standards found were of 48 ± 13.8% of intact acrosome, 73.6 ± 6.0 of perfect DNA and of 91.8 ± 4.0 of functional mitochondria. Thus, these values from the sperm analysis can be used as standards for the species Erythrolamprus poecilogyrus sublineatus.

Abstract:
O gênero Erythrolamprus (Serpentes, Xenodontinae), amplamente distribuído nas Américas do Sul e Central, inclui atualmente seis espécies de falsas corais e apresenta taxonomia complexa. Devido aos padrões morfológicos conservativos de folidose, as espécies definem-se principalmente com base em características de coloração, cujo poder diagnóstico jamais foi testado num panorama geográfico adequado com amostragem representativa da variação geral do grupo. Não obstante, a literatura sugere que as variações de coloração das espécies de Erythrolamprus podem estar intimamente associadas a complexos miméticos envolvendo formas peçonhentas simpátricas do gênero Micrurus. O presente estudo traz uma revisão taxonômica das espécies incluídas em Erythrolamprus baseada numa amostra de 1786 espécimes representativa de sua abrangência geográfica. Foram analisados caracteres de morfologia externa (folidose e coloração) e interna (hemipênis e dentição), sendo os caracteres contínuos submetidos a extenso tratamento estatístico. As decisões taxonômicas finais basearam-se em comparações diretas com o material tipo pertinente (sempre que possível) e num levantamento histórico da literatura envolvendo a taxonomia do gênero. Ao todo, são reconhecidas de 12 espécies plenas de Erythrolamprus, três destas sem nomes disponíveis e que devem ser descritas como novas. Adicionalmente, a análise da morfologia das presas pós-diastêmicas sugere uma mudança ontogenética de um estado áglifo (juvenil) para a condição opistóglifa, presente nos adultos da ampla maioria das espécies. A comparação preliminar dos principais padrões de anelação das espécies do gênero com formas simpátricas de Micrurus reforça as indicações da literatura referente a complexos miméticos, apontando para a tendência ao aparcimento de populações com anéis pretos simples (mônades) nas regiões em que são freqüentes espécies de corais verdadeiras com anéis nesta conformação. Finalmente, sugerem-se possíveis padrões de diferenciação geográfica para o grupo, a serem testados futuramente por estudos filogenéticos
The genus Erythrolamprus (Serpentes, Xenodontinae) includes six species presently recognized, widely distributed in South and Central America and showing a complex taxonomic history. Due to general uniformity in overall pholidotic patterns, diagnostic features of such taxa are mostly associated to coloration and have never been tested in a comprehensive approach of the variation and geographic range of the group. Nonetheless, literature suggests that populational variation in color patterns of Erythrolamprus might be strongly associated to simpatry with poisonous coral snake species of the genus Micrurus. This study brings a taxonomic revision of the species included in Erythrolamprus based on a sample of 1786 specimens covering the wide distributional range of the genus. External (scale counts and coloration) and internal (hemipenis and teeth) morphology provided the main sources of characters used herein; the continuous variables were submitted to detailed statistical treatment. The final taxonomic decisions were based in comparison with type material (whenever possible), along with an investigation of the taxonomic history of the group. The results of the present revision support the recognition of 12 full species of Erythrolamprus, three of which still lacking available names. Additionally, the analysis of tooth morphology suggests an ontogenetic change form the aglyphous pattern (juveniles) to the opistoglyphous condition, present in the adults of most species. A preliminary comparison of the color patterns shown by the Erythrolamprus species with the ones of sympatric taxa of Micrurus supports previous indications of the existence of mimicry complexes, pointing out to the tendency of monadal typed populations of Erythrolamprus occurring in areas where similar poisonous coral snakes are apparently common. Finally, general patterns of geographic differentiation are suggested to the group and must be tested in future studies of explicit phylogenetic approach.

Predadores exclusivamente carnívoros, as serpentes alimentam-se de presas variadas e ocupam diferentes hábitats. As adaptações evolutivas conferidas aos ofídios permitiram o desenvolvimento de múltiplos mecanismos de percepção da presa, modo de captura e estratégias que permitem a ingestão de presas bem maiores que seu próprio tamanho. Erythrolamprus jaegeri jaegeri e Erythrolamprus poecilogyrus sublineatus são serpentes semi-aquáticas que ocorrem em simpatria no extremo sul do Brasil. O presente estudo teve como objetivo analisar a composição da dieta dessas duas espécies e, mediante contrastes, investigar os fatores associados a essas diferenças. Para isso, foram utilizados exemplares provenientes da região de estudo, depositados em coleção Herpetológica da FURG (CHFURG). Os itens alimentares foram coletados, identificados ao menor nível taxonômico possível e medidos. Adicionalmente, todas as serpentes tiveram estruturas do corpo e da cabeça mensurados. Os itens alimentares foram analisados segundo métodos qualitativos e quantitativos como Frequência de Ocorrência (FO%), Abundância Numérica (N%), Análise Gravimétrica (P%) e Índice de Importância Relativa (IRI). Os itens mais importantes para ambas as espécies foram os anuros. Diferenças na composição da dieta e o índice de Levins indicaram um caráter especialista para E. j. jaegeri e generalista para E. p. sublineatus. E. p. sublineatus é estatisticamente maior do que E. j. jaegeri e se alimenta de itens maiores. Segundo as análises de regressão, as estruturas da cabeça parecem não interferir no tamanho das presas selecionadas, enquanto isso foi observada correlação positiva entre o comprimento e o peso de predadores e presas para as duas espécies. Os resultados indicaram que, apesar de simpátricas, a composição alimentar das espécies diverge segundo dois parâmetros: o tamanho do corpo do predador que está associado ao tamanho das presas selecionadas e a diferente amplitude de nicho de cada espécie, ambos permitindo que os recursos utilizados variem entre as espécies, diminuindo a competição e possibilitando a coexistência.
Exclusively carnivorous predators, snakes feed on various prey and occupy different habitats. The evolutionary adaptations conferred on snakes allows the development of multiple mechanisms that are the perception of the prey, capture mode and strategies that allow the ingestion of larger prey. Erythrolamprus jaegeri jaegeri and Erythrolamprus poecilogyrus sublineatus are semi-aquatic snakes which live on the extreme southern Brazil. This study aimed to compare the diet of these two species and also investigate the factors associated with these differences. To performes this study we use specimens from Herpetological Collection from FURG (CHFURG). Food items were collected, identified and measured, including snakes that had injured body structures. Food items were analyzed according to the qualitative and quantitative methods as Frequency of Occurrence (FO%), Numerical abundance (% N), Gravimetric Analysis (P%) and Index of Relative Importance (IRI). The most important prey for both species were anurans. The comparison of differences in the diet and the Levins index indicated that E. j. jaegeri is specialist and E. p. sublineatus is generalist. The bar graphs to the length and weight of the predators and prey showed that E. p. sublineatus is statistically larger than E. j. jaegeri and prey on larger animals. According the regressions analysis, the structures of the head do not seem to interfere with the size of the selected prey, meanwhile positive correlation was observed between the length and weight of predators and prey for both species. Results indicated that although sympatric, food species composition differs according to two parameters: the body size of the predator that is associated with the size of the selected prey and different range of each species niche, allowing both the resources used to vary between species, reducing competition and allowing coexistence.

Abstract:
Resumo: O gênero Erythrolamprus atualmente agrupa 50 espécies que têm sido incluídas tradicionalmente nos gêneros Erythrolamprus, Liophis e Umbrivaga. Embora a recente sinonimização tem sido suportada em todas as análises moleculares, ainda existe debate, devido ao baixo número de espécies incluídas e a falta de sinapomorfías morfológicas. Dentro de Erythrolamprus, podem se reconhecer 13 grupos com base nos arranjos taxonômicos tradicionais, mas a monofilia desses grupos nunca tem sido testada. Utilizando 78 caracteres de osteologia craniana e hemipênis, e seis genes: três mitocondriais (coi, 12s, cytb) e três nucleares (bdnf, cmos, nt3); para 27 espécies, testamos a monofilia do gênero, dos grupos taxonômicos e das espécies, além do relações internas. Realizamos analises de parcimônia, bayesianos e de máxima verossimilhança para os dados moleculares; enquanto que para as matrizes morfológica e combinada (morfologia e molecular) só foi utilizada analise de parcimônia. Os nossos resultados recuperaram monofilético Erythrolamprus como atualmente aceito, nove clados principais dentro do gênero, sendo que para a maioria deles propomos sinapomorfias morfologicas. Só quatro dos grupos taxonômicos tradicionais foram recuperados monofileticos. Erythrolamprus sagittifer foi encontrada aninhada dentro de Lygophis e é realocada neste gênero. Adicionalmente, para o clado conformado por E. almadensis, E. atraventer, E. carajasensis, E. jaegeri, E.maryellenae, E. viridis ressuscitamos o gênero Leimadophis, dado que foi recuperado como irmão de todas as outras espécies do clado Erythrolamprus.
Abstract: The genus Erythrolamprus currently groups 50 species that have traditionally been allocated in the genera Erythrolamprus, Liophis and Umbrivaga. Although synonymization of these three genera with Erythrolamprus finds support in all molecular studies, the systematic value of such nomenclatural act is still under debate, mainly because of the lack of morphological synapomorphies and dense taxonomic sampling for the group. Within Erythrolamprus, 13 taxonomic groups may be recognized based in a traditional taxonomic arrangement, but its monophyly has never been tested. The present study analyzed 78 morphological characters, from cranial osteology and hemipenis, and six genes, three mitochondrial (coi, 12s, cytb) and three nuclear (bdnf, cmos, nt3), in 27 species representing all previously recognized taxonomic groups, in order to test the monophyly of the genus and of its constituent parts. We performed parsimony, bayesian and maximum likelihood analyses for the molecular data, and parsimony analyses for morphological and combined matrices (morphology and molecules). Our results retrieved a monophyletic genus Erythrolamprus as currently accepted, composed by nine main clades that are, for most of them, supported by morphological synapomorphies. On the other hand, only four of the traditional taxonomic groups were retrieved as monophyletic. Erythrolamprus sagittifer was found to be nested within Lygophis and is reallocated in that genus. Additionally, we resurrected the genus Leimadophis for the clade formed by E. almadensis, E. atraventer, E. carajasensis, E. jaegeri, E.maryellenae, and E. viridis, since it was recovered as the sister group of a clade composed by all the other species of the genus Erythtorlamprus.

Foram analisadas populações de Erythrolamprus aesculapii de diferentes Domínios Morfoclimáticos brasileiros a fim de se realizar uma revisão taxonômica. São reconhecidas atualmente três subspécies de E. aesculapii para o Brasil. Contagens de escamas e de manchas corporais foram estudadas através de análises de variância. Padrões de coloração foram classificados e o hemipênis de exemplares representantes das diferentes áreas de ocorrência da espécie também foram observados. Cinco padrões básicos de coloração foram reconhecidos. Não foram encontradas diferenças significativas no hemipênis de exemplares de diferentes áreas, mas as análises estatísticas nos permitiram separar as populações do Domínio Equatorial Amazônico das restantes populações de E. aesculapii encontradas no Brasil, pelo menos em relação ao padrão de coloração, ao número de manchas corporais e às contagens de escamas ventrais.
Populations of Erythrolamprus aesculapii from different Brazilian morfoclimatic domains were analyzed to carry out a taxonomic review. At present, three subspecies of E. aesculapii are recognized in Brazil. Scales counting and number of body rings were studied with analysis of variance. Patterns of coloration were classified and a sample of hemipenis were observed. Five basic patterns of coloration were recognized. The hemipenis of the specimens from different areas were virtually without differences, but the statistical analysis have discriminated the populations of E. aesculapii from Amazonian Equatorial Domain from the populations of others domains of Brazil, at least in relation of patterns of coloration, number of body rings and ventral scales counting.
