FIG. 1 in Redescription and Recognition of Etheostoma cyanorum from Blue River, Oklahoma

FIG. 1. Range map of E. cyanorum and E. radiosum in the south-central United States. Etheostoma cyanorum is found only in the Blue River drainage, Oklahoma, USA. Nominal subspecies E. r. radiosum is restricted to the Ouachita and Little River drainages to the east, and E. r. paludosum is restricted to the Kiamichi, Muddy Boggy, Clear Boggy systems, and tributaries of the Red River to the west. Drainages were identified by layering georeferenced collection data (http://www.fishnet2.net) into GIS software. MtDNA CR (black) and COI (gray) sampling localities are superimposed on drainages.
