Probstmayria vivipara was collected from the contents of colons of 6 out 10 donkeys. The redescription of morphology was carried out by the examination of 20 males and 20 females. The dimension of most of the determined characteristics was larger than that previously described by Neveu-Lemaire (1936), such as the total length of male and female, as well as the length of esophagous and spicules.
