| Abstract | Three species of sculpins (Pisces: Cottidae) inhabit the Ozark uplands (Arkansas and Missouri). One, Cottus hypselurus, represents a new species and is restricted to that region. It occurs through much of its range with C. carolinae and, in the Niangua River System, with C. bairdi. Although C. hypselurus shares many characters with C. bairdi, it also strongly resembles C. klamathensis of the Pacific Northwest, and its relationships within the genus are uncertain. C. hypselurus varies markedly in numbers of dorsal-fin spines and pectoral-fin rays, from river system to river system, but there is insufficient geographic consistency in this variation to merit naming subspecies. Spawning occurs in late winter or early spring depending on water temperature. |
