Abstract

Isoglaridacris hexacotyle (Linton, 1897) Mackiewicz, 1968 was found in Catostomus insignis Baird & Girard and Catostomus clarkii Baird & Girard from 3 streams in Arizona. The morphology of I. hexacotyle is revisited using light microscopy revealing new features. Emphasis is placed on the morphological variability of its scolex. The re-examination of 100 more specimens from the Gila River provided an opportunity to revise the taxonomy of the species and correct and update some old statements and concepts by other observers.
