Abstract:
A new species of nematode, Cylicostephanus longiconus, was collected from mountain zebra, Equus zebra hartmannae (Matschie, 1898), on the Kelpie farm in the Khomas Hochland, South West Africa/Namibia. These nematodes have 1 large dorsal and 2 small subventral teeth in the oesophageal funnel and submedian papillae with very long tips. The males have a very well-developed dermal collar and genital cone.
