Bokermannohyla nanuzae (Bokermann & Sazima 1973) and B. feioi (Napoli & Caramaschi 2004) belong to the B. cir-cumdata species group. The type locality of the former is Serra do Cipó, Espinhaço mountain range, and of the latter is Parque Estadual do Ibitipoca, Mantiqueira mountain range, both in Minas Gerais State, Brazil. Differences on dorsal draw-ing pattern of adults, oral disc morphology of tadpoles, and temporal properties of calls were proposed to distinguish these two species. However, several specimens found between the two type localities remain unidentified because diagnostic characters and states occur in all of these populations. Thus, in order to assess these characters variations, we performed an analysis of the morphology and morphometry of adults, vocalization, and morphology of tadpoles. Specimens were divided into three operational taxonomic units (OTUs): B. nanuzae (Serra do Cipó and northwards, Espinhaço mountain range), B. cf. nanuzae (Quadrilátero Ferrífero, Espinhaço mountain range, south of Serra do Cipó), and B. feioi (Serra do Ibitipoca, Mantiqueira mountain range). Drawing patterns of the dorsum and limbs show clinal variation and the three units are morphometrically very similar. Temporal and spectral properties of calls overlap in these three units. The diagnostic differences originally proposed for tadpoles are intrapopulational variations and occur in specimens from all of the locations analyzed. We found that these three units are morphologically indistinguishable. Therefore, we designate Bok-ermannohyla feioi (Napoli & Caramaschi 2004) as a junior synonym of Bokermannohyla nanuzae (Bokermann & Sazima 1973), extending its geographical distribution to the Mantiqueira mountain range.
纳努扎博克曼蛙（Bokermannohyla nanuzae，博克曼和萨齐马，1973年）和费奥伊博克曼蛙（B. feioi，那不勒斯和卡拉马什，2004年）属于环纹博克曼蛙物种组。前者的模式产地是巴西米纳斯吉拉斯州埃斯皮尼亚苏山脉的锡波山，后者的模式产地是曼蒂凯拉山脉的伊比蒂波卡州立公园。有人提出，可根据成体的背部图案、蝌蚪的口盘形态以及鸣声的时间特性来区分这两个物种。然而，在两个模式产地之间发现的几个标本仍未被鉴定出来，因为所有这些种群都存在诊断特征和状态。因此，为了评估这些特征的变化，我们对成体的形态和形态测量、鸣声以及蝌蚪的形态进行了分析。标本被分为三个操作分类单元（OTU）：纳努扎博克曼蛙（锡波山及以北，埃斯皮尼亚苏山脉）、纳努扎博克曼蛙相似种（费里费罗四边形地区，埃斯皮尼亚苏山脉，锡波山以南）和费奥伊博克曼蛙（伊比蒂波卡山，曼蒂凯拉山脉）。背部和四肢的图案显示出渐变变异，这三个单元在形态测量上非常相似。这三个单元的鸣声的时间和频谱特性存在重叠。最初提出的蝌蚪的诊断差异是种群内变异，并且在所有分析地点的标本中都有出现。我们发现这三个单元在形态上无法区分。因此，我们将费奥伊博克曼蛙（那不勒斯和卡拉马什，2004年）指定为纳努扎博克曼蛙（博克曼和萨齐马，1973年）的次异名，将其地理分布扩展到曼蒂凯拉山脉。
