Resumen
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.
