A new species of Vexillata (Nemata: Ornithostrongylidae) from the coarse-haired pocket mouse Chaetodipus hispidus in New Mexico.

Individuals of a new species of trichostrongyloid nematode of the genus Vexillata were collected from the intestines of the coarse-haired pocket mouse Chaetodipus hispidus from eastern New Mexico. This new species possesses general features of the genus Vexillata but may be recognized as distinct from all other species by unique features of the dorsal ray of the caudal bursa and the synlophe.
