Telmatobius halli was the first endemic Telmatobius species described in Chile, reported by Noble in 1938 near the locality of Ollagüe, in the high Andean zone of the Antofagasta region. To this date, there are no specimens assignable to this species other than the type series; although many expeditions have tried to search for T. halli, they have been unsuccessful, but they have found and described new species around this area. In order to clarify the origin of the enigmatic T. halli, we reviewed the itinerary of the expedition carried out by F. G. Hall in the Chilean Altiplano, to place a putative type locality. We contrast the morphology of the holotype, with that of recently collected specimens from the new putative type locality, to confirm the population's identity; and finally, we perform phylogenetic analyses in order to clarify the systematic position of this taxon. The historical review of the expedition that collected these frogs shows that it is likely that Telmatobius halli had been collected near Collahuasi, about 50 km northwest of Ollagüe, site that we have assigned as a putative type locality for T. halli. The morphological analyses support this hypothesis, while phylogenetic results show that the specimens assigned to this species form a monophyletic group, and is a sister clade of T. chusmisensis. Thus, we propose that the type locality of T. halli be changed from "around Ollagüe" to the area of the Copaquire ravine, so its distribution would be restricted to this system and Choja-Chijlla ravine, both in the high Andean zone of the Región de Tarapacá, Chile.
哈氏的的喀喀湖蛙是智利描述的首个特有种的的喀喀湖蛙，由诺布尔于1938年在安托法加斯塔地区安第斯山脉高处的奥亚圭附近报道。迄今为止，除模式系列外，没有可归为该物种的标本；尽管许多考察队试图寻找哈氏的的喀喀湖蛙，但均未成功，不过他们在该地区周围发现并描述了新物种。为了弄清神秘的哈氏的的喀喀湖蛙的起源，我们查阅了F.G.霍尔在智利高原进行的考察行程，以确定一个假定的模式产地。我们将正模标本的形态与最近从新的假定模式产地采集的标本的形态进行对比，以确认该种群的身份；最后，我们进行系统发育分析，以弄清该分类单元的系统位置。对采集这些蛙类的考察的历史回顾表明，哈氏的的喀喀湖蛙很可能是在奥亚圭西北约50公里处的科亚瓜西附近采集的，我们已将该地点指定为哈氏的的喀喀湖蛙的假定模式产地。形态分析支持这一假设，而系统发育结果表明，归为该物种的标本形成一个单系类群，并且是丘斯米森斯的的喀喀湖蛙的姐妹分支。因此，我们提议将哈氏的的喀喀湖蛙的模式产地从“奥亚圭附近”改为科帕基雷峡谷地区，这样其分布将限于该系统以及智利塔拉帕卡地区安第斯山脉高处的乔亚 - 奇利亚峡谷。
