While travelling as part of the protected area management activities undertaken by the Instituto Chico Mendes de Conservação da Biodiversidade (ICMBio) in the state of Acre, four records of porcupines (Coendou spp.) were gathered: two for Coendou bicolor and two for Coendou prehensilis. The records for Coendou bicolor are the first for Brazil while the records for Coendou prehensilis present the state of Acre as a potential region of sympatry between C. bicolor and C. prehensilis.

ABSTRACT. Local diversity and infl uence of seasonality on amphibians and reptiles assemblages in the Reserva Extrativista Chico Mendes, Acre, Brazil. Despite the high richness of amphibians and reptiles known for the southwestern portion of the Brazilian Amazon, the knowledge of these is punctual and few studies have evaluated the temporal variations in the occurrence and abundance of species. The goals of this study were to present the amphibians and reptiles assemblages in a locality of the Chico Mendes Extractive Reserve, verify which climate variables infl uence the temporal fl uctuations in richness and abundance, and identify the main species of the amphibians and reptiles infl uenced by them. The study area is located in the Seringal Etelvi region, southwestern portion of the Reserve, municipality of Brasiléia, state of Acre. Data collection took place between October 2011 and September 2012, for 48 sampling days, using the methods of searches limited by time and pitfall traps. There were recorded 978 specimens of 31 amphibians and 54 reptiles. Higher richness and abundance of amphibians occurred during the rainy season, with the monthly abundance positively associated with the mean temperature. Only the abundance of reptiles was higher during the rainy period. However, both richness and abundance were positively associated with mean temperature. Four amphibians, Allobates gr. marchesianus, Hamptophryne boliviana (Parker, 1927), Boana geographica (Spix, 1824) and Rhinella marina (Linnaeus, 1758), and two reptiles, Kentropyx pelviceps Cope, 1868 and Norops fuscoauratus (D'Orbigny, 1837), had their monthly abundances positively associated with the mean temperature. The lizard Dactyloa punctata (Daudin, 1802) had the monthly abundance associated with precipitation. It was possible to verify the increase of richness and abundance of amphibians and reptiles during periods when the availability of resources is favorable for many species. Species can react diff erently to climatic variations, whereas others are sensitive to fl uctuations, others seem answer easily or not reduce their abundances in periods theoretically unfavorable.KEYWORDS.

We present a list of snake species found in 10 municipalities in the Cerrado of western Bahia state, Brazil. One hundred and twenty individuals of 46 species from seven families were examined. We also present a new state record for the genus Phalotris Cope, 1862 and a candidate new species for the genus Thamnodynastes Wagler, 1830.

We describe a new species of the genus Apostolepis found near São Salvador Hydroelectric Power Plant, municipality of São Salvador do Tocantins, in the central Cerrado ecoregion. The new species is distinguished from its congeners by the following combination of characters: presence of eleven dorsolateral stripes, five infralabial scales and the lack of preoculars scales. The new species shares some external characteristics mainly with A. arenaria, A. gaboi and A. nelsonjorgei, with which it is compared.

Studies in remnants of semi-deciduous seasonal forest of the Cerrado are needed to fill sampling gaps and improve basic knowledge of biodiversity. This study presents data on the herpetofauna of Parque Estadual Altamiro de Moura Pacheco, one of the last protected areas of seasonal forest in the core region of the Brazilian Cerrado. Fourteen sites were sampled between March 2007 and April 2008 using pitfall traps and active searches. A total of 35 anuran species were recorded, most of which were found in hygrophilous environments near forest fragments, open areas and riparian or gallery forest. A total of 29 reptile species were recorded, most of which were found in semi-deciduous forest and riparian or gallery forest. Fourteen of the amphibians and five of the reptiles are endemic to the Cerrado. The richness of amphibians and reptiles found in Parque Estadual Altamiro de Moura Pacheco is regionally representative, with communities typical of forest environments.

Apostolepis gaboi was described based only on the holotype found in the Queimadas, state of Bahia, northeastern Brazil. Since its original description, no additional specimens were reported in literature and the species was considered to be rare and poorly known. Here, we provide a detailed description for the species based on the examination of the holotype and 34 additional specimens from the type locality and adjacent areas. Additional information is also provided on intraspecific color variation and hemipenial morphology.

An adult female specimen of Drymoluber brazili (Gomes, 1918) was found dead on road BR 135, one kilometer south of the city of São Gonçalo do Gurguéia, Piauí, Brazil. This is the second record of this species for the state of Piauí extending the species range 50 km south, 305 km west and 510 km north.
