Color geographically variable. There are 2 subspecies: Noturus hildebrandi latus with shorter head and with 4 white or light yellow oval areas on uniform red-brown to black back; is strongly bicolored with brown to black upper side, white or yellow below. Noturus hildebrandi hildebrandi possesses longer head and prominently blotched color pattern above and almost to belly (Ref. 86798).
