TELORCHIS-GUTTUROSI SP-N (TREMATODA-TELORCHIIDAE) FROM GRAPTEMYS-PSEUDOGEOGRAPHICA GRAY IN NEBRASKA, WITH REPORTS OF ADDITIONAL SPECIES OF TREMATODES FROM NEBRASKA TURTLES

One species of digenean is described and 8 others reported from turtles in Nebraska [USA]. T. gutturosi, described from G. 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. T. necturi is considred the senior synonym of T. cryptobranchi; G. pseudogeographica is a new host. Hapalorhynchus stunkardi is reported for the 1st 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 1st time from Nebraska. G. pseudogeographica is a new host for Heronimus mollis; Kinosternon flavescens is a new host for Telorchis corti.
