Pheidole species groups

The abundance and diversity of Pheidole means these ants have long been taxonomically challenging group, although in recent years much has been done to improve our understanding at all taxonomic levels, from their higher level relationships to their species identities.

For the New World, E.O. Wilson (2003) organized the then 625 known species into 19 species groups. Subsequent studies have added to and amended this modern foundation.

The Pheidole in other regions are less consolidated in any single modern, revisionary framework but there are numerous advances that are bringing our knowledge of the Pheidole beyond the New World into sharper taxonomic focus. This page is meant to serve as an index to some of this Pheidole work, above the species level, here on Antwiki and elsewhere.
