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).

A new record of Rondonops biscutatus (Reptilia, Sauria, Gymnophthalmidae) from Mato Grosso, Brazil

Rondonops biscutatus is a Iphisini species known from the southwestern portion of the Brazilian Amazon forest, in the states of Mato Grosso, Pará and Rondônia. In this study, we report the second known locality for the species in Mato Grosso, extending the distribution of the species approximately 545 km.

First record of Rhinella poeppigii (Tschudi, 1845) in Brazil (Anura, Bufonidae)

Rhinella poeppigii, member of the Rhinella marina group, which currently consists of 11 species, inhabits primarily cloud forests in the central Andes of Peru, Ecuador, and Bolivia, reaching lowlands adjacent to the Andes, at elevations of 260–1800 m. This work presents the first record of R. poeppigii in Brazil, from the municipality of Assis Brasil, in the state of Acre. This record extends the distribution of the species 242 km northeast of the nearest record in Explorer’s Inn, Madre de Dios province, Peru.

A new record for Melanophryniscus moreirae (Miranda-Ribeiro, 1920) (Amphibia, Anura, Bufonidae) in the state of Minas Gerais, Brazil

Melanophryniscus moreirae is recorded from a fifth locality. A specimen was collected in Serra do Papagaio, municipality of Alagoa, Minas Gerais, Brazil, 18 km southeast from the nearest previous record in Aiuruoca. This new record fills a gap of about 32 km in the distribution of the species, between Itamonte and Aiuruoca.

Hydrops martii (Wagler, 1824) (Serpentes, Dipsadidae): first record in Amapá state, northern Brazil

Hydrops martii is a poorly known water snake of the tribe Hydropsini, which has been extensively found across northern South America. In this study, we present the first record in Amapá, based on a single specimen from the municipality of Macapá (0.0333, –51.0666), in the tropical moist broad-leafed forests of northern Brazil. This record extends the species range ca 195 km north from its nearest known record, on Marajó Island, in Pará, in the same ecoregion.

First confirmed record of Atractus maculatus (Serpentes, Dipsadidae) from the state of Pernambuco, northeastern Brazil

Atractus maculatus , classified as Data Deficient by the Brazil’s Ministerio do Meio Ambiente, is recorded from a sixth known locality. The specimen was collected in the municipality of Paudalho, state of Pernambuco, Brazil. This is the first confirmed record of A. maculatus from this state and extends this species’ distribution by 153 km northeast of previously known occurrences. A map shows the occurrences throughout the whole range of this species.

New record and distribution extension of Atractus paraguayensis Werner, 1924 (Serpentes: Dipsadidae) [with erratum]

The dipsadid ground snake, Atractus paraguayensis , occurs in Southern Brazil, Southern Paraguay and Argentina. In this study, we report the most austral record of the species in Brazil, based on a specimen captured in Capao do Leao, in the campus of the Universidade Federal de Pelotas. This extends the species geographical distribution 354 km – south, of Colorado, Brazil, the most austral record of the species until now.
