Origin and Diversification of the Family
Extremely important for dating the appearance of oestrids is the presence of Tracheomyiinae in Australia. As already mentioned (Part C), two possibilities exist to explain their presence there: (i) oestrids colonized Australia from the Oriental Region by a long-range, island-hopping dispersal, a sweepstake route; (ii) oestrids in Australia are relicts of an ancient, peri-Antarctic, Gondwanan distribution.
