Abstract

One species of digenean is described and 8 others reported from turtles in Nebraska. Telorchis gutturosi, described from Graptemys pseudogeographica, resembles T. stossichi, T. pseudoaculeatus, and T. pleroticus in having an acetabulum significantly smaller than the oral sucker, but differs by possessing a pharynx which is as large as the acetabulum and having the ovary only 1/10 the body length from the acetabulum. Telorchis necturi is considered the senior synonym of T. cryptobranchi; Graptemys pseudogeographica is a new host. Hapalorhynchus stunkardi is reported for the first time since its description. Based on new morphological evidence, the generic diagnosis of Hapalorhynchus is emended and a key to the species provided. Spirorchis scripta, S. parvus, Protenes angustus, and Eustomos chelydrae are reported for the first time from Nebraska. Graptemys pseudogeographica is a new host for Heronimus mollis; Kinosternon flavescens is a new host for Telorchis corti.
