Abstract

The species Proceratophrys cristiceps belongs to the genus Proceratophrys within the family Cycloramphidae. These amphibians are found exclusively in South America in the morphoclimatic domain of the semi-arid depression zones in northeastern Brazil known as the Caatinga. We examined intrapopulational variation using univariate and multivariate statistics with traditional and geometric morphometrics, which supported the existence of two morphotypes of this species. Our results indicated significant degrees of variation in skeletal characteristics between some natural populations of this species. Careful analyses of variability levels are fundamental to avoid taxonomic errors, principally in populations that demonstrate characteristics intimately associated with their area of occurrence, as is the case of Proceratophrys cristiceps.

摘要

cristiceps角蟾物种属于Cycloramphidae科的Proceratophrys属。这些两栖动物仅在南美洲巴西东北部半干旱凹陷地带的形态气候区域被发现，该区域被称为卡廷加。我们使用单变量和多变量统计方法以及传统和几何形态测量学来研究种群内变异，这支持了该物种存在两种形态型。我们的结果表明，该物种的一些自然种群之间在骨骼特征上存在显著程度的变异。仔细分析变异水平对于避免分类错误至关重要，特别是对于那些表现出与其出现区域密切相关特征的种群，cristiceps角蟾就是这样的情况。
