On the advertisement call of Dermatonotus muelleri (Boettger, 1885) (Anura, Microhylidae)

摘要

As presently recognized, Dermatonotus muelleri (Boettger, 1885) occurs throughout Argentina, Bolivia, Brazil and Paraguay (Brusquetti & Lavilla 2006); Paraguay referred as the type-locality (Frost 2013). Its advertisement call was briefly described byNelson (1973) based on a sample from Brazil. In the present work, we redescribe its advertisement call based on a large sample from the Cerrado biome of Triangulo Mineiro region, state of Minas Gerais.Field records were gathered on 17 October 2012 at the municipality of Gurinhata (19°02'02.05"S 49°46'07.76"W; approximately 516 m a.s.l), region of the Triangulo Mineiro, state of Minas Gerais, Brazil. The regional climate is wet/ hot from September toMarch and mild/dry in the other months (IBGE 1978); the original vegetation was Cerrado, portions of which can still be found as scattered patches. Recordings were made between 21:00—23:12h.
