Cyriocosmus elegans is a spider species in the genus Cyriocosmus and the family Theraphosidae (tarantulas) found in Venezuela, Trinidad and Tobago. Cyriocosmus elegans is a fossorial species of tarantula that is known to reach maturity quickly, sometimes in a year's time. Adult size is around 1.5" to 2" diagonal leg span (DLS), from leg I on one side to leg IV on the opposite side. Second instar spiderlings are around 1/16" to 1/8" DLS and will readily accept pre-killed feeders, fruit flies, or even a cricket leg.
