Identification

Easily distinguished from the other species by its relatively uniform color and flat carapace. (1)

Where Coriarachne and Bassaniana are both found they can be identified by the hairs on the carapace. See Rod Crawfords comment; "This is either Coriarachne brunneipes or Bassaniana utahensis. The key feature is whether the large setae on the carapace have pointed ends (Coriarachne) or blunt ends (Bassaniana)."
