Abstract

Telmatobufo venustus was one of the rarest endemic amphibians of Chile until 2020. Prior to that year, this species had been known in four localities, three of them with uncertain location, including the type locality. However, three new precise localities have been reported successively since 2020, all based on a few individuals. In this study, we review the geographic information on the species and, based on literature and other documents, tentatively locate the three localities with uncertain location published before 2020. Furthermore, we describe a new locality near the uncertain southern end of its distribution. Although the number of localities has considerably increased since 2020, the species still has a highly fragmented known distribution, its type locality and southern limit cannot be located with certainty, and it is found in only two state-protected areas. Due to these reasons and because threats to the habitat have been identified in some localities, we suggest keeping the species as Endangered.
稀有和濒危的 Telmatobufo venustus (Philippi, 1899) (Anura, Calyptocephalellidae) 的地理分布,以及新地点的描述和对模式产地的评论
在 2020 年之前,Telmatobufo venustus 一直是智利最稀有的特有两栖动物之一。在这一年之前,该物种已知有四个地点,其中三个地点不确定,包括模式产地。然而,自 2020 年以来,又陆续报告了三个新的确切地点,均以少数个体为基础。在本研究中,我们回顾了该物种的地理信息,并根据文献和其他文件,初步确定了 2020 年之前公布的三个不确定地点。此外,我们还描述了靠近其分布不确定的南端的一个新地点。尽管自 2020 年以来,该物种的分布地数量已大幅增加,但其已知分布仍然非常零散,其模式产地和南端分布区无法确定,而且仅在两个国家保护区内发现该物种。由于这些原因,并且在一些地方发现了对栖息地的威胁,我们建议将该物种保留为濒危物种。
