Description of Oxynema xerusi n. sp. (Nematoda: Subuluroidea) parasitic in Xerus erythropus and Heliosciurus gambianus (Sciuridae) in Senegal.

A new species of the genus Oxynema Linstow 1899, is described from the African sciurids Xerus erythropus and Heliosciurus gambianus. Oxynema xerusi n. sp. is characterized by the lack of cervical and caudal alae and by having unequal spicules. It differs from the closest species, Oxynema linstowi Deshmukh, 1987 and Oxynema bioccai Campana-Rouget, 1956, by the number, shape, and distribution of the caudal papillae, the length of the spicules, and the ratio of spicule length to body length.
