On advertisement call of the poison frog Ameerega berohoka (Dendrobatidae, Anura) from the Brazilian Cerrado.

The poison frog genus Ameerega (Dendrobatidae) currently contains 32 species. They are distributed from central Brazil into western Amazonia to the lower Andean versant. In addition, three trans-Andean species have been allocated to Ameerega (Andrade et al. 2013; Frost 2014). Ameerega berohoka (Vaz-Silva & Maciel 2011) was described based on specimens from central Brazil (type-locality: Arenópolis, GO) and it is assumed to occur in parts of western and southwestern state of Goiás (Frost 2014). More recently, Andrade et al. (2013) extended its distribution to the state of Mato Grosso. Here we re-describe the advertisement call of A. berohoka, providing additional information regarding its temporal structure and spectral traits. Our observations also consist of a new distribution record for this species to the state of Mato Grosso. Field work was conducted on 16–17 November 2012 at the Parque Estadual Serra Azul (PESA), municipality of Barra do Garças (15.850767 S, 52.270808 W, approximately 533 m a.s.l.), state of Mato Grosso, Brazil. Recordings were made between 07:27–08:05 hrs. The most representative habitats in PESA are cerrado rupestre (hill savanna on rocky soil), cerrado sensu stricto, gallery forest and semi-deciduous forest (Sanchez & Pedroni 2011). The average annual rainfall in PESA is 1528 mm and the average temperature 25.5 °C (Pirani et al. 2009). One recorded male is deposited at Museu de Biodiversidade do Cerrado, Universidade Federal de Uberlândia, municipality of Uberlândia, state of Minas Gerais, Brazil (AAG-UFU 1310).
