Redescription, synonymy, and new records of Vexillata noviberiae (Dikmans, 1935) (Nematoda: Trichostrongylina), a parasite of rabbits Sylvilagus spp. (Leporidae) in the United States

Vexillata noviberiae (Dikmans, 1935) (Trichostrongylina: Heligmosomoidea), originally described as a parasite of Sylvilagus floridanus from Louisiana, is redescribed from material collected from Sylvilagus palustris in Florida and from S. floridanus in Kansas. New morphometric and morphological data are provided. Stunkardionema halla Arnold, 1941, described from S. floridanus from Kansas and New York, is proposed as a junior synonym of V. noviberiae. These findings confirm the occurrence of V. noviberiae as a parasite of rabbits and its wide distribution range in North America.
