Myiasis in the blue wildebeest [Connochaetes taurinus (Burchell, 1923)] and the
hartebeest [Alcelaphus buselaphus (Pallas, 1766)] caused by Gedoelstia spp. is described.
The incidence of the first stage larvae within various tissues is recorded and
further evidence submitted to elucidate their migratory pattern. The most important
histological lesions including pachymeningitis and periophthalmitis are recorded.
In spite of the constant dural myiasis and frequent pachymeningitis the affected
antelopes show no apparent serious clinical manifestations.
