A New Species of Amphisbaena from Northeastern Brazil (Squamata: Amphisbaenidae)

We describe a new species of Amphisbaena from the Caatinga in the northern region of Bahia, northeastern Brazil. The new taxon is identified mainly by having two precloacal pores, 158–165 body annuli, 12–14 caudal annuli with autotomy on the third and fourth annuli, 14–16 dorsal and 15–16 ventral se...

Summary:We describe a new species of Amphisbaena from the Caatinga in the northern region of Bahia, northeastern Brazil. The new taxon is identified mainly by having two precloacal pores, 158–165 body annuli, 12–14 caudal annuli with autotomy on the third and fourth annuli, 14–16 dorsal and 15–16 ventral segments on a midbody annulus, four supralabials, three infralabials, and a postmalar row. Its description increases to 23 the number of species of Amphisbaenia for the Caatinga. Knowledge of worm lizard richness has largely increased in Brazil since the 1990s, especially in the Caatinga and the Cerrado, due mainly to collections in previously unsurveyed areas for environmental impact assessments. Nós descrevemos uma nova espécie de Amphisbaena da Caatinga na região norte da Bahia, nordeste do Brasil. O novo taxon é identificado principalmente por possuir dois poros pré-cloacais, 158–165 anéis corporais, 12–14 anéis caudais com autotomia no terceiro e quarto anéis, 14–16 segmentos dorsais e 15–16 segmentos ventrais em um anel no meio do corpo, quatro supralabiais, três infralabiais, e uma fileira pós-malar. Sua descrição eleva para 23 o número de espécies de Amphisbaenia para a Caatinga. O conhecimento sobre a riqueza de espécies de cobras-de-duas-cabeças tem aumentado intensamente no Brasil desde a década de 1990, especialmente na Caatinga e no Cerrado, em maior parte devido a coletas em áreas previamente não amostradas para fins de estudos de impacto ambiental.
