The genus Homoeomma has 13 species distributed in Argentina, Brazil, Colombia, Peru and Uruguay. In Argentina, two species are cited, Homoeomma elegans (Gerschman & Schiapelli, 1958) in Misiones province and H. uruguayense (Mello-Leitão, 1946) in Buenos Aires, Entre Ríos and Santa Fe provinces. The objective of this work is to provide the first record of Homoeomma uruguayensis in the mountainous system of central Argentina, belonging to western record of the genus in this country. In addition, we provide data on natural history of the species, some notes on its sexual behavior and through the species distribution modelling we discussed about the geographic distribution of the species and factors that could led to this pattern.
