Nothing is known about the biology of Metapone titan.


The large size (which we expect will also characterise the workers) immediately identifies M. titan among all Metapone species discussed here. The clypeal and petiolar structures and sculpturation are also unusual in the genus.

General and diagnostic features, sculpture, pilosity and colour as illustrated and in the key to Melanesian and Pacific species. Clypeus relatively broadly rostrate over almost its full width; anterior border straight; anterolateral corners slightly acute, anterolateral borders minutely concave apically, as illustrated. Petiole in dorsal view overall somewhat wider than long; dorsal posterolateral spines well developed, acute, apices minutely rounded. Subpetiolar edge concave, posterior subpetiolar angle approximately right angled, subpetiolar a relatively long, narrow posteriorly-directed hook-like process.
