Ancestral atherinids must have moved together with the Australian continent, an interpretation which is consistent with Talent's opinion (1984) who stated that species must have arisen in Gondwana prior to its fragmentation and as the Gondwanian continents separated, further speciation of the Craterocephalinae must have taken place between the emergent southern part of the island of New Guinea and northern Australia.
It has been suggested that tribe Canthonini (Scarabaeidae: Scarabaeinae) has an ancient Gondwanian distribution with high species richness in South America (Halffter 1974).
In addition, Aristolochia in America is not a monophyletic group, indicating that sympatry of differente clades in Central America is secondary in terms of the presence of the predominantly Laurasian subgenus Siphisia and the predominantly Gondwanian sect.
