Tarantulas of this genus are characterized by their large size, and the lack of long hairs in the patella and tibia sections of the legs. It can also be further distinguished by the presence of stridulating hairs on the prolateral coxae 1 and 2. Females also own a unique single spermatheca.[3]
These tarantulas are found in holes in the ground, usually abandoned burrows, which they adopt and use as their own. They are usually found near rivers, and eat a great amount of invertebrates and very small vertebrates, such as small frogs and lizards.[3]
As of July 2022[update] the World Spider Catalog has accepted the following 3 species:[4]
One species has been changed to the genus Sericopelma.
