Afrotropical Tetramorium species groups

NOTE: this page is benefiting from the unvaluable comments of Paco Hita-Garcia, and reflect some unpublished points of view about the genus structure.

The following species groups are defined according to Bolton (1980) with the following modifications:


 * Species groups from the former genus Triglyphothrix according to Bolton (1976) are kept as valid species groups. Exception to this rule are Tetramorium arnoldi, placed under the simillimum group by Bolton (1980), and Tetramorium rothschildi moved to solidum species group following Bolton (1985)


 * A new globulinode group is created with the former Rhoptromyrmex species


 * A new decem  group is defined following Hita-Garcia & Fischer (2014)


 * weitzeckeri group structure follows Hita-Garcia et al (2010)
