O girino de Chiasmocleis alagoanus Cruz, Caramaschi & Freire, 1999 (Anura: Microhylidae)

O girino de Chiasmocleis alagoanus e descrito pela primeira vez a partir de exemplares coletados na Mata do Catole, municipio de Maceio, Alagoas, Brasil. O girino tem habitos lentico e nectonico. Corpo triangular em vista lateral e oval em vista dorsal; focinho truncado em vista lateral, dorsal e ventral. Olhos laterais e aberturas nasais ausentes. Espiraculo mediano e com ampla abertura. Tubo anal ventral curto com abertura central, sem margem livre. Abertura oral terminalmente localizada, sem pecas queratinizadas. Abas labiais superiores semicirculares recobrindo parcialmente a abertura oral. Fileiras de denticulos corneos ausentes. Comprimento da cauda correspondendo a 59,1% do comprimento total. Em preservativo o corpo e castanho claro e as visceras parcialmente visiveis. Notas sobre o ambiente e comparacao com outros girinos do genero sao apresentados.

Description of the Tadpole of Proceratophrys renalis (Miranda-Ribeiro, 1920) (Anura: Cycloramphidae)

ABSTRACT. The tadpole of Proceratophrys renalis is described based on specimens from Maceió, State of Alagoas, northeastern Brazil. At stage 35 the body is slightly dorso-ventrally depressed, ovoid in lateral, dorsal, and ventral views. Oral disc is ventral with lateral emarginations, surrounded by a single row of marginal papillae with a large gap on the upper labium. Labial tooth row formula is 2(2)/3(1). The analysis of internal oral anatomy revealed two possible characters that readily distinguish P. renalis from P. boiei, supporting the recent ressurection of P. renalis. Comparisons with available descriptions of the larvae for other species in the genus are provided.

Larval morphology and advertisement call of Phyllodytes acuminatus Bokermann, 1966 (Anura: Hylidae) from Northeastern Brazil

This paper describes the tadpole and advertisement call of Phyllodytes acuminatus, based on specimens from the Parque Nacional do Catimbau, in the municipality of Buíque, State of Pernambuco, Northeastern Brazil. The overall morphology of P. acuminatus tadpole is similar to that of most species of the genus. The presence of a double row of marginal papillae surrounding all the oral apparatus (except on most of the upper labium which has a dorsal gap) was a characteristic that differentiate P. acuminatus from the other species of the genus. Furthermore, the call structure of the species (unpulsed notes with harmonic structure) fits it in the group composed of P. kautskyi and P. melanomystax.

Reproduction of Agalychnis granulosa Cruz, 1989 (Anura: Hylidae)

We provide a detailed description of the reproduction of the tree frog Agalychnis granulosa, including its advertisement call. Agalychnis granulosa breeds in ponds and the backwaters of streams within primary forests. The breeding season started at the beginning of the wet season and ended two months before the beginning of the dry season. Males called at night in the vegetation around the ponds at a maximum distance of 5 m from the water. The call was composed of a single note with three to seven pulses and a dominant frequency ranging from 1490 to 2101 Hz. Oviposition sites included tree trunks, attached leaves, fallen leaves and bromeliad roots, and ranged in height from 0 to 300 cm above the water. Egg clutches were composed of approximately 45 eggs encapsulated by a transparent gelatinous matrix. Empty egg capsules (4–7 per clutch) were recorded in 36% of the clutches. Great plasticity was observed in the reproductive strategies of A. granulosa, probably reflecting the varying competition and predation at the different life stages of the species.

The tadpole of Hypsiboas atlanticus (Anura, Hylidae) from northeastern Brazil

The tadpole of Hypsiboas atlanticus (Caramaschi & Velosa, 1996) is described from the municipality of Maceio, State of Alagoas, Brazil. At stage 36 the larvae have an overall elliptical body in lateral and dorsal views, oral disc anteroventral, spiracular tube sinistral, and labial tooth row formula 2(1,2)/3(1). The oral disc is surrounded, almost completely (anterior medial gap present) by a single row of marginal papillae. Described tadpoles of the H. punctatus species group can be differentiated by a combined disc oral features. Additional descriptions of H. punctatus (Schneider, 1799) tadpoles from populations throughout South America may be helpful in determining the status of these populations.

First records of Chthonerpeton arii Cascon and Lima-Verde, 1994 (Amphibia: Gymnophiona: Typhlonectidae) out of the type locality

Chthonerpeton arii was described from a large series of specimens from Limoeiro do Norte municipality, state of Ceara, Brazil. Here we provide the first records of the species out of the type locality, in the state of Bahia, and in its border with the state of Pernambuco, Brazil. We also provide color photographs of a preserved specimen.
