Parasites of South African wildlife. XI. Description of a new race of Cooperia rotundispiculum Gibbons & Khalil, 1980.

During surveys of the helminths of South African wildlife, a Cooperia sp. that closely resembles Cooperia rotundispiculum Gibbons & Khalil, 1980, was recovered from several antelope species. This nematode has spicules 0,140-0,248 mm long and has 18-20 longitudinal cuticular ridges, whereas typical C. rotundispiculum has spicules 0,179-0,226 mm long and has 14 ridges. In view of the few differences between the 2 helminths, the Cooperia sp. is described here as a race of C. rotundispiculum.
