Anonychomyrma extensa

Type material of this taxon could not be located by Heterick and Shattuck (2011). However, the figure provided by Emery (1887, fig. 26) matches specimens of Anonychomyrma held in and is unlike species of Iridomyrmex known from the vicinity of this species’ type locality. In this species the pronotum is relatively high and is set off from the mesonotum by an angle, and the propodeum is high and dome-like. This configuration differs from known Indonesian species of Iridomyrmex. Therefore, this name is treated as belonging to Anonychomyrma rather than Iridomyrmex.
