Observations on helminths parasitic in warthogs and bushpigs

Abstract

Helminths from warthogs and bushpigs in the Onderstepoort collection have been studied. All the species of Oesophagostomum described from warthogs were represented, except O. goodeyi and O. roubaudi. In addition two unknown species were discovered and these are described under the names O. santos-diasi and O.mozambiquei. Additional information on O. aethiopicum and O. mpwapwae is given, and a key for the identification of all the warthog oesophagostomes is drawn up. The validity of the different genera and sub-genera of Oesophagostomum is discussed. A new species of Globocephalus, viz. G. versteri is described from the bushpig. The status of the different species of this genus is critically examined and a key is given for the identification of the species considered valid. The species referred to G.urosubulatus by Maplestone (his type A specimens) is considered to be a new species and is named G. maplestoni. Filariid worms from these hosts are discussed and a new species, Setaria castroi, is described from the warthog and bushpig. The genera Hyraconema and Artionema are eliminated as synonyms of Setaria.
