November 2016 / Printed: December 2017 Abstract. Ischnocnema parva is a small species that occurs in the leaf litter within the Atlantic Forest in southeastern Brazil. The advertisement call of this species was described in the early 90’s based on an undefined number of males from Estação Biológica da Boracéia in the municipality of Salesópolis, state of São Paulo. In this study, based on data from four localities in two Brazilian states, we re-describe the advertisement call of I. parva which consists of a single type of pulsed note emitted sporadically with its fundamental frequency peaking at about 2000 Hz and its dominant frequency peaking at about 4000 Hz. The calls of males from two localities have a higher pulse rate and longer interpulse interval. Compared to our data, the call previously described in literature has a higher pulse rate and lower dominant frequency. In addition, we interpret that the species call has a harmonic structure and a distinct amplitude modulation from the previously reported.

Abstract The taxonomic status of two leptodactylid frog genera is reevaluated. Ischnocnema Reinhardt and Lütken, 1862 is considered a junior synonym of Eleutherodactylus Duméril and Bibron, and the combination E. verrucosus (Reinhardt and Lütken, 1862) is proposed.

In general, a more detailed analysis reveals that these species are, in reality, members of distinct evolutionary lineages. The geographical distribution of the species currently placed in the genus Ischnocnema Reinhardt and Lütken, 1862 presents such a gap. One species, I. verrucosa (Reinhardt and Lütken, 1862), occurs in Southeastern Brazil, and the other five, I.

O gênero Brachycephalus apresenta, em sua maioria, espécies tóxicas e de coloração conspícua, enquanto o gênero Ischnocnema possui muitas espécies polimórficas e crípticas quanto a sua coloração dorsal. No primeiro capítulo foi realizado um experimento com modelos de plasticina para testar se os padrões coloridos e brilhantes do gênero Brachycephalus estão relacionados com aposematismo. Além disso, foi testada a hipótese alóctone/autóctone, que prediz que os predadores vão responder mais fortemente a um padrão autóctone do que a um alóctone, dado que eles supostamente são ingênuos ao padrão introduzido e/ou experientes quanto ao padrão autóctone. O experimento foi realizado em duas localidades de Mata Atlântica no estado de São Paulo, Brasil, onde ocorrem tanto espécies camufladas quanto conspícuas de Brachycephalidae. Foram encontradas diferenças na intensidade de ataque entre os modelos crípticos e vistosos, suportando a hipótese de que a coloração conspícua de Brachycephalus é sinal de sua toxicidade. No segundo capítulo foi investigado como fatores ambientais e espaciais afetam os padrões de coloração de espécies do complexo de Ischnocnema guentheri-henselii e I. parva, comparando populações em diferentes latitudes depositadas no acervo de quatro coleções científicas. Os diferentes padrões foram plotados em mapas e, através de análises de agrupamento, foram detectadas diferenças na proporção da frequência dos padrões nas populações situadas no limite meridional da ocorrência das espécies. A segregação de populações abaixo da latitude -24º é coincidente com variações morfológicas observadas em outras espécies, ou mesmo com limites de distribuição de espécies irmãs de anuros.

Ischnocnema holti (Cochran, 1948) was de- scribed based on a single specimen collected in the beginning of 20th century at the Itatiaia mountain range. In this study, we present a redescription of the species based on 25 specimens (18 males and seven females) collected at the type locality. Measurements of the specimens, description of its color pattern in life, as well as aspects of its biology and reproduction are presented. Ischnocnema holti is a medium-sized species (snout-vent length from 13.5 to 31.7mm), snout shape rounded in dorsal and lateral views and digital discs well developed. Ischnocnema holti presents considerable plasticity in its morphology and coloration. This study includes I. holti in the I. lactea (Miranda-Ribeiro, 1923) group and compares it with some of its components. KEY WORDS.

Recently, the speciose genus Eleutherodactylus Duméril and Bibron, 1841 was subject to various large molecular phylogenetic analyses (Frost et al. 2006; Heinicke et al. 2007; Hedges et al. 2008), being split into several taxa.

We compared the virulence (measured as host mortality and infection burden) of hybrid Bd genotypes to the parental lineages, the putatively hypovirulent lineage Bd-Brazil and the hypervirulent Global Pandemic Lineage (Bd-GPL), in a panel of native Brazilian hosts. In Brachycephalus ephippium, the hybrid exceeded the virulence (host mortality) of both parents, suggesting that novelty arising from hybridization of Bd is a conservation concern. In Ischnocnema parva, host mortality in the hybrid treatment was intermediate between the parent treatments, suggesting that this species is more vulnerable to the aggressive phenotypes associated with Bd-GPL. Dendropsophus minutus showed low overall mortality, but infection burdens were higher in frogs treated with hybrid and Bd-GPL genotypes than with Bd-Brazil genotypes. Our experiment suggests that Bd hybrids have the potential to increase disease risk in native hosts. Continued surveillance is needed to track potential spread of hybrid genotypes and detect future genomic shifts in this dynamic disease system. Te host-parasite dynamic is a classic example of an evolutionary arms race; hosts face pressure to evolve defenses against parasites, while parasites face pressure to overcome host defenses1,2.

This species is closely related to I. juipoca (Giaretta et al., 2007; Canedo & Haddad, 2012), however, it can be distinguished from it by the smaller size (SVL: adult males 14.9–18.7 mm; adult females 19.9–20.7 mm), and differences in the advertisement call, which has more pulses and higher pulse repetition rate (Giaretta et al., 2007). Currently, I. penaxavantinho is only known from four localities in the states of Minas Gerais and Goiás (Giaretta, 2008; Bastos et al., 2015; �el �rette et al., 2018), and little is known about its natural history and population trends, being therefore classified as �ata �eficient (Giaretta, 2008; ICMBio, 2014).

Two of the most defi nitive of ders—continue to be described. Frogs are far more di- these traits are: verse than salamanders and caecelians combined; more than 6,400 (~88%) of extant amphibian species are frogs, 1. Nearly all amphibians have complex life histories. almost 25% of which have been described in the past Most species undergo metamorphosis from an 15 years. Salamanders comprise more than 660 species, aquatic larva to a terrestrial adult, and even spe- and there are 200 species of caecilians. Amphibian diver- cies that lay terrestrial eggs require moist nest sity is not evenly distributed within families. For example, sites to prevent desiccation. Thus, regardless of more than 65% of extant salamanders are in the family the habitat of the adult, all species of amphibians Plethodontidae, and more than 50% of all frogs are in just are fundamentally tied to water.

Abstract The taxonomic status of two leptodactylid frog genera is reevaluated. Ischnocnema Reinhardt and Lütken, 1862 is considered a junior synonym of Eleutherodactylus Duméril and Bibron, and the combination E. verrucosus (Reinhardt and Lütken, 1862) is proposed. Oreobates Jiménez-de-la- Espada, 1872 is revalidated, and the combinations Oreobates quixensis Jiménez-de-la-Espada, 1872, O. simmonsi (Lynch, 1974), O. saxatilis (Duellman, 1990), O. sanctaecrucis (Harvey and Keck, 1995), and O. sanderi (Padial, Reichle and De la Riva, 2005) are proposed. Epsophus verrucosus Miranda-Ribeiro, 1937 is synonymized with Eleutherodactylus verrucosus (Reinhardt and Lütken, 1862). Key words: Amphibia; Anura; Leptodactylidae; Ischnocnema; Oreobates; Taxonomy Introduction WIDELY disjunct geographical distributions among closely related species are rare in the Neotropics. In general, a more detailed analysis reveals that these species are, in reality, members of distinct evolutionary lineages. The geographical distribution of the species currently placed in the genus Ischnocnema Reinhardt and Lütken, 1862 presents such a gap. One species, I. verrucosa (Reinhardt and Lütken, 1862), occurs in Southeastern Brazil, and the other five, I.
