Davus fasciatus (formerly Cyclosternum fasciatus) has a black carapace and is rare or nonexistent in the hobby. However, the name persists, because many Davus pentaloris were mistaken sold as fasciatus.
@Ungoliant Okay I was not sure at all cause I have been reading around for husbandry stuff and I have found so many different names I appreciate the clarification!! You wouldn’t be able to point me in the direction of some good husbandry pointers for this species would you? I think I have her set up well it’s just nice to read a bit more about it.
