Salsuginus yutanensis n. sp. (Monogenea: Ancyrocephalidae) from Fundulus sciadicus in Clear Creek of eastern Nebraska

Salsuginus yutanensis n. sp. (Monogenea: Ancyrocephalidae) is described from the gills of the plains topminnow, Fundulus sciadicus Cope, from Clear Creek in eastern Nebraska. Salsuginus yutanensis is distinguished from previously described species by having a shorter accessory piece and different hamulus proportions, especially in the relative lengths of deep and superficial roots. In addition, the angles between deep and superficial roots distinguish S. yutanensis from several congeners.
