The first phylogenetic analysis of genus Urophonius is performed based on morphological characters. Three monophyletic species groups are recovered. Species of the granulatus species group and Urophonius mondacai have summer or spring activity patterns. The exochus and brachycentrus species groups form a monophyletic group with a winter activity pattern, which is so far unique in scorpions from temperate and cold areas. Additionally, two new Patagonian species of Urophonius are described, one from Argentina and one from Chile. Finally, we discuss the southernmost distributions of scorpions in continental Patagonia. We suggest that the southern limit of the group could be related not only with a decrease in temperature, but also with an increase of precipitation.

根据形态学特征，对Urophonius属进行了首次系统发育分析。回收了三个单种物种组。该种granulatus种组和Urophonius mondacai有夏季或春季活动模式。该exochus和brachycentrus物种群形成一个冬天的活动模式，这是由温带和寒带地区蝎子迄今唯一一个单系群。此外，乌罗菲尼乌斯（Urophonius）的两个巴塔哥尼亚新物种描述了一种，一种来自阿根廷，一种来自智利。最后，我们讨论了巴塔哥尼亚大陆上蝎子的最南端分布。我们认为，该组的南端不仅与温度降低有关，而且与降水增加有关。
