A new two-pored species of Amphisbaena (Squamata, Amphisbaenidae) from the Brazilian Cerrado, with a key to the two-pored species of Amphisbaena 

Abstract

A new species of Amphisbaena is described from municipalities of Babaçulândia, State of Tocantins, and Estreito, State of Maranhão, northern Brazilian Cerrado. The new species differs from other two-pored species of the genus, by presenting mainly slender body shape; snout rounded in profile and dorsal view; high number of body annuli (328-342); 12-14 dorsal segments and 14-16 ventral in midbody half-annulus; autotomic site between 9-10^th caudal annuli; absence of chevron-shaped anterior dorsal half-annuli; 20-23 caudal annuli; postmalar row absent; and precloacals pores arranged in a continuous series of the precloacal half-annuli. Additionally, we present a key for two-pored species of Amphisbaena.

Morphological characteristics of worm lizard, Diplometopon zarudnyi (Squamata: Trogonophidae), in the central region of Saudi Arabia

“…It inhabits Aeolian sand deposits and emerges onto the surface to breed (Maisano et al, 2006) but there is little detailed information on the ecology of this species. The description of amphisbaenians have been based mainly on external morphological characters, for example, number of body annuli, segments per body annulus and number of precloacal pores (Ribeiro et al, 2016). Knowledge of amphisbaenian morphology is poor compared to other squamates.…”

Clinical and post mortem examination of white worm lizards (Amphisbaena alba) in the State of Paraíba, Northeastern Brazil: morphological, pathological and radiographic findings of a secretive species

“…These highly specialized burrowing reptiles have fossorial habits and are distributed primarily in South America, Caribe, and Sub-Saharan Africa (Teixeira Junior et al 2019). In Brazil, more than 70 species have been described (Teixeira Junior et al 2019), many of them in the last decade (Pinna et al 2010, Ribeiro et al 2011, 2016, 2019, Roberto et al 2014, Teixeira Junior et al 2014, Costa et al 2015, Almeida et al 2018, Oliveira et al 2018. Three species, Amphisbaena kiriri, Amphisbaena longinqua and Amphisbaena mongoyo, have been recently described in Northeastern Brazil (Ribeiro et al 2018, Teixeira Junior et al 2019.…”

Distribution extension and a new state record for Amphisbaena mertensi Strauch, 1881 (Squamata, Amphisbaenidae) in central Brazil

“…This family is also the most widely distributed, occurring in Central and South America and Africa (Costa and Garcia 2019). In Brazil, 73 species are recognized, and 34 of them are found in the Cerrado biome (Colli et al 2002;Pinna et al 2010;Nogueira et al 2011;Gomes and Maciel 2012;Ribeiro et al 2016).…”
