Cyclosternum (Tarantulas)

Cyclosternum is a small genus of New World tarantulas found in Central and South America. These tarantulas are often overlooked due to their small size and reclusive behavior, but they exhibit beautiful metallic or bronze coloration and unique fossorial habits.

Cyclosternum species are fossorial and require enclosures with deep substrate for burrowing, moderate humidity, and good ventilation. Though small, they are hardy and can thrive in well-maintained setups. Due to their secretive nature and quick movement, they are more suitable for intermediate to advanced keepers.
