Abstract:
1. The full colour pattern of Aponomma exornatum is described, and
the range of variations within the species discussed.
2. A. arcanum and A. neglectum are put into the synonymy of A.
exornatum.
3. The conclusion is drawn that the varanids are the normal hosts,
with the crocodile as a second choice. All others are but accidental hosts.
4. The descriptions are given of the two ticks parasitic on Varanus
griseus; A. crassipes and A. fraudigerum; of the tick parasitic on Mabuya
striata; A. ochraceum; and their affinities are discussed.
