Although the Cyriocosmus genus has existed since the late 1800s, many species have only been described since the millennium. Cyriocosmus leetzi (Colombia) was introduced in 1999. A dwarf species and already a favorite in the hobby, C. leetzi has the trademark black and orange of the genus, arranged in a unique pattern. In addition, delicate white lines trace the dorsum of each leg. This hardy and fast growing species takes up only a little room on the shelf. Like all Cyriocosmus it likes to burrow, though often enough it may be seen on the surface or at the burrow entrance.
N.b., spiderlings are currently quite small, taking newly hatched crickets or fruit flies.
