Discovery of an isolated population of the dwarf tarantula Homoeomma uruguayense (Araneae, Theraphosidae) in central Argentina

The genus Homoeomma has thirteen species distributed in Argentina, Brazil, Colombia, Peru and Uruguay. In Argentina, two species are recorded, Homoeomma elegans in Misiones province and H. uruguayense in Buenos Aires, Entre Rios and Santa Fe provinces. The objective of this work is to provide the first record of Homoeomma uruguayense 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 modeling we discussed about the geographic distribution of the species and factors that could led to this pattern.
