Explanation of Names
Author of the name Gertsch. Year first published: 1942.
Size
Female 9 mm
Male 7 mm
Identification
This species is similar in general appearance to Castianeira longipalpus. It differs at sight in having the posterior tibiae marked with distinct basal and distal yellow annulae(rings)**. Carapace dark reddish brown to nearly black with thin white hairs, darker on sides. (1)

** We have not been able to see the yellow rings in photos of live Castianeira variata. At this point we are assuming we can't use this as a reliable field marking to distinguish C. variata from C. longipalpa.

Epigynum:Intact/dorsal view/ventral view
Range
This species' distribution is poorly known. It is known from Connecticut west to Kansas and as far south as Louisiana. (2)
