Abstract:Cytochrome b suggested cryptic diversity within several species of Noturus. Relationships among members of the subgenus Rabida were resolved and in many cases well supported. Relationships among Schilbeodes were poorly resolved. A calibrated substitution rate identified a period between 8 and 2 million years ago in which the majority of cladogenesis took place in Rabida. A novel hypothesis of relationships among surface-dwelling ictalurid genera is provided in which Ameiurus is the sister group to a clade composed of Ictalurus, Pylodictis and Noturus, in which Ictalurus is the sister group to Pylodictis and Noturus.
