Redescription of Atractus albuquerquei (Serpentes: Colubridae: Dipsadinae), with comments on geographical distribution and intraspecific variation

Abstract

Atractus albuquerquei Cunha and Nascimento, 1983

Atractus albuquerquei Cunha & Nascimento, 1983 (Serpentes, Dipsadidae): range extension and new country record for Bolivia

“…Specimen CIRA-834 was uniformly cream color; however, specimen CIRA-833 displayed bright-yellow ventral scales. The coloration, pattern, and meristic data of the specimens are congruent with the descriptions by Cunha and Nascimento (1983) and Zaher et al (2005) for A. albuquerquei.…”

“…Sex was determined by the probe method following McDiarmid et al (2012). Specimen identification was determined by comparing and analyzing: meristic data, morphometrics, coloration, figures, drawings, and photographs from the original description and taxonomic information by Cunha and Nascimento (1983) and subsequent rediscription by Zaher et al (2005). A comprehensive search for information on A. albuquerquei consisted of reviewing published scientific papers and online databases (i.e.…”

Atractus albuquerquei Cunha & Nascimento, 1983 (Serpentes, Dipsadidae): first record for the state of Minas Gerais, southeastern Brazil

“…These records are open Cerrado areas varying from forested savanna ("cerradão") Green mosaic = Amazon biome; yellow mosaic = Cerrado biome; ■ = type locality; • = records from literature (see Table 1 to hydromorphic open field ("vereda") ( Figure 3). Similar habitat has been reported in Zaher et al (2005), showing that the species is not only restricted to forested areas.…”

Natural history of the rare and endangered snake Atractus ronnie (Serpentes: Colubridae) in northeastern Brazil

“…The sexual dimorphism in SVL and tail length observed in Atractus ronnie is characteristic of other species in the genus (Savage 1960, Passos et al 2005, Zaher et al 2005. The SSD found here was positive, and although slightly greater, resembles that of A. reticulatus (Boulenger, 1885) (Balestrin and Di-Bernardo 2005) and other snakes from the tribe Dipsadini (Pizzatto et al 2007).…”
