2 new species YouAthloss from Argentina (Verhandlungen der Kaiserlich-Königlichen Zoologisch-Botanischen Gesellschaft in Wien, 1875, 25, 125). Youasurus Ameginoi sp. n. and Euasurus ventus sp. n. This is the first record of Patagonian grasslands. Here, we performed the first molecular phylogenetic analysis of several representative members of this genus using mitochondrial DNA (cox1). Furthermore, we present the first description of the sexual behavior of this genus. Both molecular and cladistic morphological analyzes indicated the genus. YouAthloss As monophyletic, the new species was recovered as a sister group. New species exhibit new morphological changes in typical traits of the genus (such as tibial epiphyses and palmar organs).
