The tadpole of Amazophrynella teko (Anura: Bufonidae) from the eastern Amazon, Brazil.

ABSTRACT

The genus Amazophrynella Fouquet, Recoder, Teixeira, Cassimiro, Amaro, Camacho, Damasceno, Carnaval, Moritz, and Rodrigues, is represented by 12 nominal species and distributed in the Amazon region of Brazil, Bolivia, Colombia, Ecuador, Guyana, French Guiana, Peru, and Venezuela (Frost 2020). In the last eight years, ten species from this genus have been described. However, despite the wide distribution and diversity of these species, only the tadpole of Amazophrynella manaos Rojas, Carvalho, Ávila, Farias, and Hrbek from the Brazilian Amazon (Menin et al. 2014) and A. siona Rojas, Fouquet, Ron, Hernández-Ruz, Melo-Sampaio, Chaparro, Vogt, Carvalho, Pinheiro, Ávila, Farias, Gordo, and Hrbek from Ecuador have been formally described (Duellman Lynch 1969; Rojas et al. 2018). Literature about tadpole morphology, reproduction, and bioacoustics of Amazophrynella is scarce and necessary to a comprehensive taxonomic classification (Kaefer et al. 2019). Herein, we describe the tadpole of the recently described species Amazophrynella teko Rojas, Fouquet, Ron, Hernández-Ruz, Melo-Sampaio, Chaparro, Vogt, Carvalho, Pinheiro, Ávila, Farias, Gordo, and Hrbek, found in the northeastern Amazon, in the State of Amapá, Brazil, and in French Guiana.
