Euathlus
Euathlus is a genus of South American tarantulas that was first described by Anton Ausserer in 1875. These spiders are medium sized and are usually found in high elevations in the Andes. It is a senior synonym of Paraphysa, and was formerly considered a senior synonym of Brachypelma, but this was later rejected.

Diagnosis 
Males own a palpal bulb with two prolateral keels, with the tip curved retrolaterally. The tibial apophyses has retrolateral spines and a spine on the retrolateral branch which almost reached the apex. And a urticating patch in the center of the opisthosoma, which own mainly type 3 and 4 urticating hairs. Females also can be distinguished by two 4 sided spermathecal receptacles, with sphere like chambers.
