A new species of the Amphisbaena (Squamata, Amphisbaenidae) from the Brazilian Cerrado with a key for the two-pored species.

Here, we describe a new species of Amphisbaena with two precloacal pores from open Cerrado areas of the municipality of Arenópolis, in the Brazilian state of Goiás. The new species differs from other South American amphisbaenids by the folllowing combination of characters: (1) snout rounded in dorsal view and slightly convex in lateral view; (2) two precloacal pores; (3) 161-176 dorsal half-annuli; and (4) 12-15 tail annuli. Our molecular phylogenetic analysis retrieved a monophyletic Amphisbaena silvestrii group, with A. silvestrii positioned as the sister-group of a clade formed by Amphisbaena anaemariae and the new species described herein. Members of the A. silvestrii group including A. neglecta and A. crisae not added in our phylogenetic analysis are characterized by a relatively small body, two precloacal pores, body coloration with dark and light areas, and lack of specializations on the cephalic or caudal shields. We present a key for two-pored species of Amphisbaena.

A new species of the Ololygon catharinae species group (Anura: Hylidae) from the Cerrado biome, State of Goiás, Central Brazil.

We describe a new species of Ololygon from the Cerrado biome, Central Brazil. The new species is assigned to the Ololygon catharinae species group based in morphological attributes. Ololygon goya sp. nov. in known only from type locality-Sítio d'Abadia municipality, State of Goiás-and associated with riparian environments connected to seasonal dry forest on the banks of the Corrente river, a tributary of the Paranã river basin. The new species is characterized by the combination of the following characters: medium size (24.4-38.8 mm SVL); snout subovoid in dorsal view; canthus rostralis well defined; males with hypertrophied forearms and nuptial pads; inguinal region and hidden surfaces of thigh with irregular dark brown spots on pale yellowish background. We also describe the external morphology and oral morphology of tadpoles, and the advertisement calls of the new species.

A new cryptic species of Oreobates (Anura: Craugastoridae) from the seasonally dry tropical forest of central Brazil.

A new species of Oreobates Jiménez de la Espada, 1872 is described from the seasonally dry tropical forest associated to rocky outcrops of the northeastern Goiás State, Central Brazil. Oreobates antrum sp. nov. is diagnosable by the combination of morphological characters (e.g. small size, dorsal and ventral skin texture smooth to finely shagreened, and broadly enlarged truncate discs on Fingers III and IV), call attributes (composed of a single note and no harmonics with dominant frequency ranged 2070 Hz to 3273 Hz), and supported by molecular evidence (phylogenetic position and genetic divergence) with high degree of differentiation among other Oreobates species (divergences of 4.0-20.6% for 12S, 7.0-14% for 16S, 0.7-4.0% for RAG-1, and 1.1-8.0% for TYR). The new species was recovered as the sister of Oreobates remotus.

The advertisement call of Proceratophrys branti Brandão, Caramaschi, Vaz-Silva Campos, 2013 (Amphibia, Anura, Odontophrynidae).

Proceratophrys Miranda-Ribeiro, 1920 currently comprises 40 species (Frost 2017) of which 15 are allocated into the Proceratophrys cristiceps species group (sensu Brandão et al. 2013). The species in this group are characterized by the absence of postocular swellings and, except for P. concavitympanum, are found in seasonally open habitats in Brazilian Cerrado and Caatinga morphoclimatic domains (Giaretta et al. 2000; Ávila et al. 2012; Teixeira Jr. et al. 2012; Brandão et al. 2013). Information on advertisement calls is available for 11 species of the group (Eterovick Sazima 1998; Nunes Juncá 2006; Brasileiro et al. 2008; Santana et al. 2010; Ávila et al. 2012; Martins Giaretta 2011; 2012; 2013; Ferreira et al. 2016). Proceratophrys branti Brandão, Carmaschi, Vaz-Silva Campos, 2013 has been recently described and allocated in the P. cristiceps species group. The species occurs in open areas in the north-central portion of the Brazilian Cerrado, in the states of Goiás, Minas Gerais and Tocantins (Brandão et al. 2013). Herein we describe for the first time its advertisement call, based on recordings made in an area of Cerrado biome in the state of Tocantins.

The advertisement call and geographic distribution of Proceratophrys dibernardoi Brandão, Caramaschi, Vaz-Silva & Campos 2013 (Anura, Odontophrynidae).

Proceratophrys dibernardoi Brandão, Caramaschi, Vaz-Silva & Campos 2013 has recently been described and allocated into the P. cristiceps species group, but no information about its advertisement calls has been provided (Brandão et al. 2013). Here, we describe for the first time the advertisement calls of P. dibernardoi based on specimens from Central Brazil. We also expand P. dibernardoi´s geographic distribution by reporting a new population in the State of Mato Grosso do Sul, Brazil, constituting the westernmost record for this species, and extending its known range approximately 330 km westward of the municipality of Aporé, State of Goiás (P. dibernardoi´s former westernmost record).

Three new species of Proceratophrys Miranda-Ribeiro 1920 from Brazilian Cerrado (Anura, Odontophrynidae).

Based on the analyses of specimens collected at several areas in the Cerrado domain from Central Brazil and others housed in scientific collections and on specimens collected at the type-locality, herein we describe three new species belonging to the P. cristiceps group: Proceratophrys bagnoi sp. nov., from UHE Serra da Mesa power plant (13°49'47.5"S, 48°19'17"W; 570 m a.s.l.; WGS84 datum), Municipality of Minaçu, State of Goiás; Proceratophrys branti sp. nov., from Jalapão, Municipality of Mateiros (05o15'25"S, 48o12'00"W; 109 m a.s.l.; WGS84 datum), State of Tocantins; and Proceratophrys dibernardoi sp. nov., Municipality of Mineiros (17o33'52"S, 52o33'20"W; 803 m a.s.l.; WGS84 datum), State of Goiás. The diversity of Proceratophrys in Brazilian Cerrado is still underscored and several species will be described in the following years.

Anfíbios anuros associados a corpos d'água do sudoeste do estado de Goiás, Brasil / Anuran amphibians associated to water bodies in Southwest of Goiás State (Brazil)

O Cerrado é o segundo maior bioma brasileiro e é considerado um dos mais importantes hotspots de biodiversidade. Neste bioma foram registradas cerca de 150 espécies de anuros, das quais 30 por cento são endêmicas. Entretanto, existem muitas áreas ainda não inventariadas, nas quais não se conhece quase nada sobre a diversidade de anuros. Assim, neste estudo apresentamos informações referentes a anurofauna do sudoeste do Estado de Goiás (Brasil Central), a qual vem sendo modificada principalmente pela agropecuária. Nesta região, 45 corpos d'água foram amostrados entre os meses de novembro/2007 a fevereiro/2008 e novembro/2008 a março/2009, localizados próximos a plantações de soja, cana-de-açúcar, pastagem e vegetação nativa. No total, foram registrados adultos e girinos de 36 espécies de anuros, a maioria comum de áreas abertas. As curvas de acumulação de espécies, tanto para adultos quanto para girinos, apresentaram a formação de uma assíntota, o que indica uma baixa probabilidade de registro de novas espécies mesmo com a amostragem de outros corpos d'água. Nesta área com forte influência de impactos agrícolas, a riqueza encontrada representa aproximadamente 1/4 do total de espécies conhecidas para o bioma Cerrado.

The Cerrado is the second largest biome in Brazil and is considered one of most important among the biodiversity hotspots. In this biome can be found about 150 anurans species, from which 30 percent are endemic. However, there are many Cerrado areas that have little information gathered about the anuran biodiversity. Thus, in this study we present the result of an inventory of anurans species from the southwest region of Goiás State (Central Brazil). In this region, we sampled 45 water bodies, located near soybean and sugar-cane cultures, pastures and natural vegetation, from November/2007 to February/2008 and from November/2008 to March/2009. Altogether, adults and tadpoles of 36 species were registered, with the majority of species registered in association to open areas. The rarefied curve of species richness show an asymptote formation, which indicates that the chance to add species to the inventory is low, even with additional habitats sampling. Therefore, our results reveal high species richness in the present sampled region, which represented almost one fourth of all species found in Cerrado.
