A new cryptic species of poison frog is described from Central Brazil and included in the Ameerega picta group. Ameerega berohoka sp. nov. occurs in cerrado sensu stricto and gallery forest phytophysiognomies in the Cerrado biome in areas drained by the Araguaia River basin, State of Goiás, Brazil. The new species differs from the other species in the A. picta group by adult morphology, such as dorsal coloration, hand length, nostril shape, and features of advertisement call. Uncorrected p-distances of a fragment of the 16S mitochondrial rRNA gene revealed high divergence among other Ameerega species. The new species seems to be genetically most similar to Ameerega flavopicta (ca. 5.3%).

A new species of Pristimantis (Anura: Strabomantidae) from the Pristimantis conspicillatus group is described from theCerrado biome in central Brazil. Pristimantis ventrigranulosus sp. nov. is found in riparian forests associated with a par-ticular palm tree called “babaçú” (Attalea speciosa: Aracaceae) in northwestern Goiás state of Brazil. The new species isonly known from the type locality: Fazenda Macaúba (16°35’23” S; 51°47’43” W, approximately 400 m above sea level),Piranhas Municipality in the state of Goiás. The new species differs from the other species in the P. conspicillatus groupmainly by having, an homogeneously granular belly, Finger I > Finger II, dorsal skin coarsely shagreen, toe and fingerfringes weakly developed or absent, presence of basal webbing and tarsal fold, single nuptial pad on thumb, moderatelydeveloped and round discs on Fingers III and IV, and higher dominant frequency than other Pristimantis with similar calls(ranging 3451.8−4334.8 Hz). The new species shows an advertisement call equal in structure to the calls of P. dundeei, P. fenestratus, P. koehleri and P. vilarsi. Pristimantis dundeei is transferred to the P. conspicillatus group.

We describe a new species of poison frog from the Serranías de Santiago and Chochis, isolated Precambrian sandstone massifs in the Chiquitanía region of Bolivia. The new species is morphologically similar to the Brazilian Ameerega braccata and A. flavopicta and best distinguished by larger adult size (27.57 mm versus < 22 mm in A. braccata) and coloration of ventral surfaces in life (light grey to light brown with black marbling versus yellowish white with occasional black marbling in A. flavopicta), respectively. The new species is genetically most closely related to A. flavopicta (uncorrected p-distances of the 16S mitochondrial rRNA gene ca. 2 %) but clearly differs in characteristics of its advertisement call (longer note duration, lower note repetition rate, lower number of pulses per note, and lower fundamental and dominant frequency). The new species can be commonly found in the vicinity of rocks, often near running water, and should be considered 'Least Concern' (LC) under IUCN Red List criteria.

Based on concordant differences in male advertisement call, tadpole morphology, and absence of haplotype sharing in the barcoding 16S mitochondrial DNA, we describe here a new species of spotted leaf frog of the genusPhasmahylafrom Atlantic Forest, State of Rio de Janeiro, Southeast Brazil. The new species is most similar toP. cochranae(type locality) andP. spectabilis(type locality). It differs from these species by the size of the calcar, moderate-sized body (snout-vent length 30.4–34.4 mm in adult eight males), and in the advertisement call. The tadpoles ofPhasmahyla lisbellasp. nov. differ fromP. exilis,P. spectabilis,P. timbo,P. guttataandP. jandaiabecause they do not have row of teeth in the anterior part; differ fromP. cruziby the shape of the anterior end of the oral disc. Through genetic data (phylogenetic distance and haplotype genealogy) we diagnosed the new species where the genetic divergences among its congeners is about 3–6% in a fragment of the 16S rRNA gene, which is above the threshold typically characterizing distinct species of anurans. However, the new species can be distinguished from other congeneric species based on an integrative approach (molecular, bioacoustics, larval, and adult morphology).

We describe a new species of forest frog in the genus Platymantis from New Britain Island, Bismark Archipelago, Papua New Guinea. The new species is a morphologically cryptic form that has masqueraded for almost four decades under the name P. schmidti (formerly P. papuensis schmidti, Brown & Tyler, 1968). The new species is microsympatric with the geographically widespread P. schmidti at two known localities. We diagnose the new species on the basis of its distinctive advertisement call and slight but consistent differences in body size and proportions. Calling males of the new species appear to prefer more elevated perches than do males of P. schmidti and the new species may exhibit a greater extent of sexual size dimorphism.

Com o objetivo de conhecer a fauna de formigas que coabita os cupinzeiros de Cornitermes cumulans (Kollar) no Cerrado sensu stricto do Brasil Central, foram realizadas coletas em 36 cupinzeiros em três localidades. Os cupinzeiros foram fragmentados e o material coletado foi armazenado em frascos com álcool a 80%. Apresentamos aqui uma lista das formigas associadas aos cupinzeiros de C. cumulans. Um total de 61 espécies distribuídas em nove subfamílias e 32 gêneros foi coletado. A subfamília Myrmicinae apresentou o maior número de gêneros (15) e de espécies (22). Estes resultados indicam que ninhos de cupins são importantes recursos de nidificação para várias espécies de formigas no Brasil Central. Ants (Hymenoptera, Formicidae) Associated with Nests of Cornitermes cumulans (Kollar) (Isoptera, Termitidae) in the Cerrado of Central Brazil Abstract. In order to survey the ant fauna inhabiting termite nests of Cornitermes cumulans (Kollar) in the Cerrado sensu stricto of Central Brazil, we collected inquiline ants in 36 termitaries in three localities. Termite mounds were fragmented and the ants collected and preserved in 80% ethanol. Here we present a list of the associated ants found in mounds of C. cumulans. A total of 61 species belonging to nine subfamilies and 32 genera were collected. The subfamily Myrmicinae had the largest number of genera (15) and species (22). The results indicate that termite mounds are an important nesting resource for several ant species in the Brazilian Cerrado.

The known diversity of treefrogs of the genus Phyllodytes has rapidly increased in recent years, currently comprising 14 species. Recent field work in the Atlantic Rainforest of the state of Bahia lead to the discovery of a new large species of Phyllodytes which is herein described based on multiple evidence including morphological, acoustical and genetic data. Phyllodytes sp. nov. is one of the largest species within the genus and presents immaculate yellowish dorsum and limbs. The advertisement call of the species is composed of 7–31 notes (half pulsed/pulsatile-half harmonic) with frequency-modulated harmonics. Phyllodytes sp. nov. has a karyotype of 2n = 22 chromosomes, as also found in other species of the genus. Genetic distance values of the 16S mitochondrial rRNA among Phyllodytes sp. nov. and its congeners range between 6.4 to 10.2%. The description of another new species for this state reinforces the need for further taxonomic work with Phyllodytes in this region that has been revealed as a priority area for research and conservation of this genus.

Boana xerophylla is a common treefrog widely distributed in northern Brazil, Colombia, French Guiana, Guyana, Panama, Suriname, Trinidad and Tobago, and Venezuela. A recent study found molecular, acoustic, and morphometric differences between the populations located on opposite sides of the Orinoco River. Here, we carry out an updated molecular phylogenetic analysis, including new samples from all the countries along the distribution area, and analyzed additional call recordings from Brazil, Colombia, French Guiana, Panama, Trinidad and Tobago, and Venezuela. Our phylogenetic inference reveals three geographically restricted lineages: one in the eastern Guiana Shield (corresponding to B. xerophylla sensu stricto), another in the western Guiana Shield, and a third one north of the Orinoco River. Morphological and acoustic data agree with the differentiation between the populations north of the Orinoco River and the eastern Guiana Shield despite the low genetic p-distances observed (16S rRNA: 0.7–2.2 %). We argue that the populations north of the Orinoco River correspond to a new species, sister of B. xerophylla. We name and describe Boana platanera sp. nov. from the southern versant of the Cordillera de Mérida (08º48’26’’ N, 70º30’46’’ W, WGS 84; 947 m asl), Venezuela, and refer all the populations north of the Orinoco River currently identified as B. xerophylla to this species. The new species can be readily diagnosed from B. xerophylla (characters of the latter in parentheses) by a pale orange-yellow or light brown dorsal coloration (dark brown to green), palpebral membrane with dark pigments (pigments absent); pericloacal region dark brown (cream), advertisement call with shorter first note length than B. xerophylla. This study represents an empirical example regarding false negatives behind genetic thresholds for species discovery, appraising the use of integrative taxonomic approaches.

The Neotropical frog genus Pseudopaludicola includes 25 species distributed throughout South America. Herein we review the taxonomic status of P. parnaiba relative to P. canga and the specific identity of the population treated in previous studies as Pseudopaludicola sp. 3 from Barreirinhas in the Brazilian state of Maranhão. The lack of differentiation in advertisement call, morphology, and mitochondrial markers from topotypes and different populations rejects the status of P. parnaiba and Pseudopaludicola sp. 3 from Barreirinhas as distinct species. For these reasons, we suggest to formally consider P. parnaiba as a junior synonym of P. canga. We also found that a population previously reported as P. facureae from central Brazil (Palmeiras de Goiás, Goiás) corresponds to a cryptic species that we describe here as a new species. Lastly, we provide for the first time the phylogenetic positions of P. giarettai, P. llanera and P. pusilla.

Based on concordant differences in morphology, male advertisement call, and 16S mtDNA barcode distance, we describe a new species of Proceratophrys from southern Amazonia, in the states of Mato Grosso and Pará, Brazil. The new species is most similar to P. concavitympanum and P. ararype but differs from these species by its proportionally larger eyes and features of the advertisement call. Additionally, genetic distance between the new species and its congeners is 3.0–10.4% based on a fragment of the 16S rRNA gene, which is greater than the threshold typically characterizing distinct species of anurans. Using an integrative approach (molecular, bioacoustics, and adult morphology), we were able to distinguish the new species from other congeneric species. The new species is known only from the type locality where it is threatened by illegal logging and gold mining as well as hydroelectric dams.
