Phylogeny of Leptomyrmex

Relationships among selected species of the ant genus Leptomyrmex based on Lucky 2011.

From the abstract: "Monophyly of the genus Leptomyrmex was recovered, as was the sister-group relationship of ‘micro-’ and ‘macro-’ Leptomyrmex species. Divergence dating analyses estimate that Leptomyrmex arose in the Eocene (stem age ~44 million years ago (ma)), and that the ‘macro-’ species diverged from the ‘micro-’ species in the early Oligocene (~31 ma). Diversification of the crown group ‘macro-’ and ‘micro-’ Leptomyrmex occurred in the Miocene (~15 ma and 7.9 ma, respectively). New Guinea and New Caledonian lineages appear to have diverged from Australian lineages only recently (~4.7 ma and 10.3 ma, respectively), and the latter clade is inferred to have reached New Caledonia from Australia via long distance dispersal."
