Abstract

Cyathostomum montgomeryi (Boulenger, 1920) K'ung, 1964, a common parasite of zebras, has not been redescribed since its original description. It is still almost unknown outside of Africa. This species was placed in differenttribes (Murshidiinea or Cyathostominea) by recent workers. As part of an international effort to clarify the classification of the Cyathostominae of horses, we studied 210 specimens from Burchell's zebra Equus burchelli antiquorum Smith, 1841, from the Kruger National Park (Republic of South Africa) and Etosha National Park (Namibia) and made measurements of 15 males and 15 females. Specimens that we measured were larger than those described by Boulenger. Cyathostomum montgomeryi has 2 corona radiata or leaf crowns surrounding the mouth. The internal leaf crown (ILC) is inserted near the middle of the buccal capsule. The external leaf crown (ELC) has fewer elements than the ILC. The bases of the ILC elements are inserted in a curved line on the wall of the buccal capsule, and those of the ELC elements are recessed from the tips of the elements of the ILC on which they rest. All of thesecharacters are shared with the other species of the genus Cyathostomum. The extrachitinous supports are similar to those of Cyathostomum catinatum. The distal ends of the spicules are identical to others in the Cyathostominea but differ from those in the Murshidiinea. The bursa is typical for Cyathostamum. Thus, we retain this species in the Cyathostominea.
