A new six-pored Amphisbaena (Squamata: Amphisbaenidae) from the coastal zone of northeast Brazil

Abstract

We describe a new Amphisbaena from the Brazilian coastal zone at the municipalities of Guamaré and Macau, state of Rio Grande do Norte. The new species, Amphisbaena littoralis sp. nov., is characterized by six precloacal pores, 252-264 body annuli, 30-34 tail annuli with autotomy on the 6^th tail annuli, 20-22 dorsal and 21-24 ventral segments to the midbody annulus.

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

“…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.…”

Herpetofauna recorded by a fauna rescue program in a Caatinga area of João Câmara, Rio Grande do Norte, Brazil

“…For Amphisbaenia, 4 species were found in the study area. At least 7 species are known in the state (Perez and Ribeiro 2008, Freire et al 2009, Roberto et al 2014, Caldas et al 2016. Our record of Amphisbaena littoralis is the second record from RN and represents a range extension and a new habitat.…”

“…Our record of Amphisbaena littoralis is the second record from RN and represents a range extension and a new habitat. The study area is 65 km southeast from the type locality (Guamaré, RN) and is in Caatinga stricto sensu habitat very different from the marine influenced environments where the species was found previously (Roberto et al 2014).…”

“…Although this list can be representative of the groups and the biome, it is out of date. In the last decade, many surveys were performed and new species were described, while taxonomic revisions revealed endemic taxa (Heyer and Juncá 2003, Borges-Nojosa and Santos 2005, Rodrigues et al 2006, Arias et al 2011, Ribeiro et al 2012, Cavalcanti et al 2014, Guedes et al 2014a, Pires et al 2014, Recorder et al 2014, Roberto et al 2014.…”

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).…”
