ABSTRACT

The Neotropical amphibian family Centrolenidae currently includes 156 named species of nocturnal anurans commonly known as glassfrogs. With 79 species, Colombia is the country with the highest diversity of centrolenids. However, the number of species known to occur in the country remains uncertain because research often results in names being resurrected or placed in synonymy, the description of new taxa, and range extensions of species, including new country records. Based on field trips and assess of additional specimens, herein we report new distribution data for centrolenids species in Colombia. These data include six new distribution records for: (Cochranella granulosa, Nymphargus balionotus, N. chami, N. grandisonae, Hyalinobatrachium mondolfii, and H. pellucidum). Records of C. granulosa and H. pellucidum are the first records of these species from Colombia. Thus, our study increases to 81 the numbers of glassfrogs for this country. Because most Hyalinobatrachium have a conservative morphology, making species identification problematic when only based on external traits, we sequenced a fragment of the mitochondrial gene 16S to confirm species identities within a phylogenetic context. We discuss the taxonomic implications of our results for the recognition of species and populations that are morphologically similar to H. talamancae.

摘要

新热带两栖动物科 Centrolenidae 目前包括 156 种已命名的夜行无尾目动物，通常称为玻璃蛙。哥伦比亚有 79 个物种，是中心粒细胞多样性最高的国家。然而，该国已知的物种数量仍然不确定，因为研究通常会导致名称被复活或置于同义词、新分类群的描述以及物种的范围扩展，包括新的国家记录。基于实地考察和对其他标本的评估，我们在此报告了哥伦比亚中心线虫物种的新分布数据。这些数据包括六个新的分布记录：（Cochranella granulosa、Nymphargus balionotus、N. chami、N. grandisonae、Hyalinobatrachium mondolfii 和 H. pellucidum）。C. granulosa的记录和H. pellucidum是来自哥伦比亚的这些物种的第一个记录。因此，我们的研究将这个国家的玻璃蛙数量增加到 81 只。由于大多数Hyalinobatrachium具有保守的形态，因此仅基于外部性状使物种鉴定存在问题，我们对线粒体基因 16S 的片段进行了测序，以确认系统发育背景下的物种身份。我们讨论了我们的结果对识别在形态上与H. talamancae相似的物种和种群的分类学意义。
