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

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 by Nelson (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 Triângulo Mineiro region, state of Minas Gerais.

目前学界公认，穆氏盾蟾（Dermatonotus muelleri，Boettger, 1885）广泛分布于阿根廷、玻利维亚、巴西及巴拉圭全境（Brusquetti & Lavilla，2006）；其模式产地被认定为巴拉圭（Frost，2013）。纳尔逊（Nelson，1973）曾基于巴西的一份标本，对该物种的求偶鸣唱（advertisement call）进行了简要描述。本研究基于采自巴西米纳斯吉拉斯州特里扬古洛米内罗地区塞拉多生物群系（Cerrado biome）的大量样本，重新描述该物种的求偶鸣唱。
