    O gênero Phasmahyla Cruz, 1990 é composto por pequenos anuros, cujas desovas são depositadas em folhas acima de córregos na mata. Seus girinos são neustônicos e apresentam funil bucal dorsal. Na cidade do Rio de Janeiro o gênero está representado por P.guttata (Lutz 1924). Girinos desta espécie foram coletados no Rio dos Macacos, Horto Florestal, Rio de Janeiro e sua ontogenia foi estudada. A larva eclode no estágio 25 (com cerca de 16,5 mm), permanecendo neste estágio até um comprimento médio de 18,4 mm. O funil bucal cresce de 1,9 mm (estágio 25) a 7,1 mm (estádio 40), sendo completamente absorvido no final do estágio 42. A cauda cresce gradualmente até o estágio 41, quando os girinos alcançam as maiores dimensões (comprimento médio de 55,1 mm). No estágio 41, a cauda começa a ser absorvida, desaparecendo completamente no estágio 46. Nos córregos, os girinos são distribuídos em cardumes, compostos por indivíduos de diferentes estágios de desenvolvimento. A composição dos cardumes variou ao longo do ano. Nos meses de junho e julho a ocorrência de girinos recém-eclodidos não foi observada, com o aparecimento dos primeiros recém-eclodidos em agosto. Um maior número de girinos recém-eclodidos foi observado em março, abril e maio. Cinco desovas foram coletadas, todas depositadas em ninhos de folhas enroladas em forma de funil. Para a confecção dos ninhos, o casal usou apenas folhas vivas, mais longas do que largas

    Breeding biology and advertisement call of the horned leaf-frog, Proceratophrys appendiculata (Amphibia: Anura: Odontophrynidae)

    No full text
    We describe the breeding biology and the advertisement call of the horned leaf-frog, Proceratophrys appendiculata (Günther, 1873) in the Parque Nacional da Serra dos Órgãos, municipality of Teresópolis. The reproductive period of P. appendiculata is short and is associated with the end of the winter and the beginning of the spring, when males call night and day under large rocks in sandy bottom rock streams. The amplexus is axillary and one female laid about 656 viscous eggs. The advertisement call of P. appendiculata is unique among congeners. The call lasts approximately two seconds, with about 85 pulses/call at a rate of 45 pulses/s and frequency around 0.620 kHz. It is one of the longest calls and lowest in dominant frequency. Moreover, the call of P. appendiculata is characterized by the greatest number of pulses so far registered, reaching 129 pulses in a single call
