Abstract
The genus Werneckiella, parasitic on horses, asses and zebras (Perissodactyla: Equidae) and the barbary sheep (Artiodactyla: Caprinae) is described fully for the first time. Six species are described, including one new species, zebrae from Hartmann Mountain Zebra, and ocellata, a species of hitherto uncertain validity; three new synonyms and three new combinations are recognized. A species key is provided and there is a host-parasite discussion.
