A New Two-PoredAmphisbaenaLinnaeus, 1758, from Western Amazonia, Brazil (Amphisbaenia: Reptilia)

A new Amphisbaena (Squamata: Amphisbaenidae) from southern Espinhaço Range, southeastern Brazil

“…nov., A. darwinii, A. heterozonata, A. prunicolor, A. silvestrii and A. trachura would suggest a close phylogenetic relationship despite their current distributions (Gans 1966, Perez et al 2012, Teixeira et al 2014). However, considering that some morphological characters of amphisbaenids are shared by convergence (Mott and Vieites 2009) it is premature to assume if similarities among the above cited species represent synapomorphies instead of convergences.…”

“…Scale nomenclature follows Gans and Alexander (1962) and Teixeira et al (2014); morphometric measures were taken to the nearest 0.1 mm with a caliper, except for the snout-vent and tail lengths, which were measured with a flexible ruler to the nearest 1.0 mm. Body slenderness proportion (BSP) (snout-vent length / head width) follows Pinna et al (2014) (Fig.…”

“…Since the year 2000, 19 new amphisbaenid species were described in Brazil, representing 26% of its current richness. Besides the fossorial habits making amphisbaenids hard to find and collect, many Brazilian species named in the last decades were discovered during environmental impact assessments and wildlife rescues (see for a short review, Ribeiro et al 2012, Roberto et al 2014, Teixeira et al 2014. During an environmental impact assessment between August 2009 and May 2010 in Conceição do Mato Dentro, southern Espinhaço Range, state of Minas Gerais, southeastern Brazil, specimens of a small Amphisbaena were collected, which we concluded to belong to a new species described below.…”

Distribution extension and revised map of Erythrolamprus pygmaeus (Cope, 1868) (Serpentes: Dipsadidae)

“…At Jirau dam, such effort was successful in adding some knowledge on the taxonomy, geography distribution and ecology on herpetofaunistic groups (Teixeira et al 2013(Teixeira et al , 2014Dal Vechio et al 2015, this study) nonetheless, despite all the massive effort only a single specimen of Erythrolamprus pygmaeus was found. Similar surveys at nearby dams such as Samuel (Kawashita-Ribeiro et al 2011) (Figure 2) with a previous reference to this individual (MPEG 20996) in Ávila-Pires et al (2010).…”

Estrutura genética e a diversidade críptica de Cnemidophorus (Squamata, Teiidae) no Cerrado

“…Essa alta diversidade no Cerrado, no 28 entanto, ainda pode estar subestimada, uma vez que a cada ano aumenta o número de 29 espécies descritas. Com base em um levantamento no Web of Science®, entre 2012 e 2014 30 foram descritas 10 novas espécies de Squamata para o domínio (Giugliano et al, 2013;Silva 31 e Ávila-Pires, 2013; Teixeira et al, 2013Teixeira et al, , 2014Arias et al, 2014a;Pinna et al, 2014;32 Recoder et al, 2014;Roberto et al, 2014). Ainda há suspeita de que espécies conhecidas 33 sejam na verdade compostas de várias espécies crípticas, o que aumentaria mais a riqueza do domínio (Gamble et al, 2012;Giugliano et al, 2013;Teixeira et al, 2013;Domingos et al, 2014).…”
