Two new species of nematodes representing the genus Litomosoides were obtained from pocket gophers collected in the early 1960s and during 1982 in Colorado. Individuals of Litomosoides thomomydis n. sp. were recovered from the abdominal cavities of two species of pocket gopher, Thomomys tulpoides (Richardson) and T. bottae (Eydoux & Gervais). Nematodes representing L. westi n. sp. were recovered from the abdominal and pleural cavities of the plains pocket gopher Geomys bursarius (Shaw) from eastern Colorado. These two species of filarioid nematodes appear to be restricted in geographical range to those pocket gophers inhabiting the central grasslands and Rocky Mountain region of the United States and Canada.
