First record of Siphlophis compressus ( Daudin , 1803 ) ( Serpentes , Dipsadidae ) from the state of Roraima , Brazil

We present the first record of Siphlophis compressus from the state of Roraima, Brazil. This report, from the Serra do Tepequém, extends this species’ distribution in Brazil by 789 km to the northwest of the nearest previous locality recorded (Manaus, Amazonas, Brazil).


NOTES ON GEOGRAPHIC DISTRIBUTION
Alagoas, Paraíba and Ceará, altough in Ceará, only 1 record is known (from a humid area of city of Fortaleza; Guedes et al. 2011).
In this study, we present the first record of S. compressus from the state of Roraima, which also represents an additional record from the Amazon Forest.This new record extends the distribution of S. compressus about 789 km to the northwest of the city Manaus, Amazonas (Fig. 1) (Guedes et al. 2011).

Methods
On 10 August 2015, at 8 pm, we found an individual of S. compressus (Fig. 2) foraging on the forest ground of Serra do Tepequém (03.7683, -061.7602,datum WGS84, elev.620 m, in municipality of Amajari, state of Roraima, Brazil.The Serra do Tepequém is composed of a flat plateau, located in the northwestern region of Roraima, with altitudes ranging from 600 to 1200 m above sea level.Its vegetation types comprises open areas (fields, savannas and valleys), surrounded by continuous patches of Amazon Forest.
After we photographed the specimen, we collected it (Collection permit SISBIO 7422-1).The voucher specimen is housed in the Museu de Zoologia da Universidade de São Paulo (MZUSP 22598).During the capture, the individual vibrated its tail as a defensive display, as previously reported by Fraga et al. (2013) and Gaiarsa et al. (2013).
Discussion Guedes et al. (2011) mentioned that S. compressus may be endangered in many regions, although widely distributed and abundant in some localities (MAF pers.obs.).Our record, the first from the state of Roraima, extends this species' distribution northwest by 789 km in the Amazon Forest domain.Thus, S. compressus is an inhabitant of almost all Brazilian states that are inserted in the Amazonia biome, except for Maranhão (Guedes et al. 2011).Surveys of the herpetofauna and related studies in the state of Roraima are scarce (Carvalho 2009), and we suggest that further studies are urgently needed in Roraima in order to improve our knowledge about the chorology of Amazonian snakes.
