ABSTRACT
For a total 23 valid species, in Northeastern Brazilian States were observed ten species of Tropidurus, being three founded in Ceará State [T. hispidus (Spix, 1825), T. jaguaribanus Passos et al., 2011 and T. semitaeniatus (Spix, 1825)]. New localities were found in Municipality of Cariré, in Ceara State, in Brazil. The comparision of specimens of Tropidurus of Cariré region and others Brazilian species was allowed the identification of these individuals as T. hispidus. In T. jaguaribanus and T. semitaeniatus was not observed the necklace shape band as the first specie. These species was showed the characteristic and conspicuous stripe extends dorsally from snout to scapular region or to the base of tail, respectively.
Key words: Tropidurus hispidus, Cariré, new localities.
INTRODUCTION
Tropidurus Wied-Neuwied, 1825 is a genus of South American lizards with cis and trans-Andean distribution (Frost, 1992). The genus is distributed over open tropical and subtropical habitats, mainly in the South American arid region, in Amazonian savanna enclaves, and in a large area of the Brazilian Atlantic coast (Rodrigues, 1987, 1988; Ávila-Pires, 1995). Tropidurus species are usually associated with rocky outcrops or sandy soils (Rodrigues, 1987; Kohlsdorf et al., 2001). For a total 23 valid species, in Northeastern Brazilian States were observed ten species of Tropidurus, being three founded in Ceará State [T. hispidus (Spix, 1825), T. jaguaribanus Passos et al., 2011 and T. semitaeniatus (Spix, 1825)]. While T. jaguaribanus shows a more restricted distribution (Municipality of São João do Jaguaribe), T. hispudus is distributed in wide area of Brazil, since Amazonas and Roraima States and Northeastern region to Minas Gerais and Rio de Janeiro States, and other countries (Colombia, French Guyana, Suriname and Venezuela) (Carvalho, 2013). This distribution area is one of the largest for Tropidurus. In this paper was showed the new locality for T. hispidus, in Municipality of Cariré, inside Caatinga Biome, Brazil.
MATERIAL AND METHODS
It was observed, in nature, a total of 10 specimens of Tropidurus, in the limits of the city of Cariré (03°56’59.96”S 40°28’15.47”W), in the semi-arid region of Ceará, Brazil. Distribution data was obtained from the literature (23 species actually valid) and observed specimens (northeastern specimens, included of the new locality).
Map of new locality of T. hispidus and literature marks of nearest species was elaborated with Quantum-Gis 2.18 program.
RESULTS AND DISCUSSION
The comparision of specimens of Tropidurus of Cariré region (figs. 1, 2) and others Brazilian species was allowed the identification of these individuals as T. hispidus. The color pattern was of great value for the determination of this species. The individuals observed in the city of Cariré presented a clear black band around the neck of these animals, as well as the lighter pattern of their coloration (grayed out) and form and distribution of spots in the dorsal region, as well as in the flanks, coincided equally with the usual found in T. hispidus specimens from known localities, included areas of Caatinga Biome of Ceará State where was collected (eg. Itapagé, Itapipoca and Maranguape municipalities). In T. jaguaribanus and T. semitaeniatus was not observed the necklace shape band. These species was showed the characteristic and conspicuous stripe extends dorsally from snout to scapular region or to the base of tail, respectively (Passos et al., 2011).
CONCLUSION
Due to the overlap in several diagnostic characters (clear black band around the neck, lighter pattern coloration and distribution of spots in the dorsal region and in the flanks) between specimens of Tropidurus from the Cariré region, Ceará, Brazil and specimens identified as T. hispidus from adjacent areas, it was concluded that these individuals from Cariré belong to the same species, whose distribution area has been expanded this article.
