In this study, we describe a new species of Pseudapatemon collected from American woodcock (Scolopax minor) in Wisconsin and Nebraska. The new Pseudapatemon species is characterized by the distribution of vitellarium, which extends into the prosoma and holdfast organ. This is the fifth species of this genus and the third described from North America. We also provide a supplemental description of Pseudapatemon aldousi based on specimens from S. minor in Wisconsin. Our description provides an improved understanding of the holdfast organ and other major structures of P. aldousi, as our specimens were not as strongly curled as those described in previous studies.<\/jats:p>","DOI":"10.1645\/25-103","type":"journal-article","created":{"date-parts":[[2026,4,7]],"date-time":"2026-04-07T02:42:55Z","timestamp":1775529775000},"page":"183-188","source":"Crossref","is-referenced-by-count":0,"title":["A New Pseudapatemon (Digenea: Diplostomoidea) from the American Woodcock and Redescription of Pseudapatemon aldousi"],"prefix":"10.1645","volume":"112","author":[{"given":"Roxanne M.","family":"Gasperetti","sequence":"first","affiliation":[{"name":"Department of Biology, University of North Dakota, 10 Cornell Street, Stop 9019, Grand Forks, North Dakota 58202."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah A.","family":"Orlofske","sequence":"additional","affiliation":[{"name":"Department of Biology and Olson Museum of Natural History, University of Wisconsin \u2013 Stevens Point, 2001 4th Avenue, Stevens Point, Wisconsin 54481."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vasyl V.","family":"Tkach","sequence":"additional","affiliation":[{"name":"Department of Biology, University of North Dakota, 10 Cornell Street, Stop 9019, Grand Forks, North Dakota 58202."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2472-4372","authenticated-orcid":false,"given":"Tyler J.","family":"Achatz","sequence":"additional","affiliation":[{"name":"Department of Natural Sciences, Middle Georgia State University, 100 University Parkway, Macon, Georgia 31206."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1220","reference":[{"key":"1","doi-asserted-by":"crossref","unstructured":"T.
