Polychromatism of populations of Corallus hortulanus (Squamata: Boidae) from the southern Amazon Basin, Brazil Acta Amazonica
DUARTE,Mel de Oliveira; FREITAS,Tiago Magalhães da Silva; PRUDENTE,Ana Lúcia da Costa.
The Amazon tree boa Corallus hortulanus is known for featuring a wide variation in color pattern and design markings. Although there are studies on its polychromatism, none of them addresses the geographic variation in the color pattern of this species. The aim of this study was to describe the chromatic variation found in the populations of C. hortulanus from the southern Amazon Basin and its relationship with geographic distribution of the species. Analysis of both design markings and color patterns on 112 C. hortulanus specimens from the southern Amazon Basin interfluves resulted in the identification of six distinct morphotypes. Grayish-brown coloration and elongated diamond-shaped patterns were the most frequent patterns. Two morphotypes showed a...

MENESES,Afonso Santiago de Oliveira; CITELI,Nathalie Kaladinsky; PRUDENTE,Ana Lúcia da Costa; Albuquerque BRANDÃO,Reuber.
ABSTRACT Atractus potschi is a small Brazilian endemic snake. Its distribution is restricted to Brazil's Northeastern Atlantic Rain Forest and Caatinga biomes, in the States of Alagoas, Bahia, and Sergipe. Herein, we expanded its distribution in hinterlands by 270 km from the nearest previous record. This is also a new occurrence on the left bank of the São Francisco River.
