Afrotropical Tetramorium species groups

AntWiki: The Ants --- Online

NOTE: this page is benefiting from the invaluable comments of Paco Hita-Garcia, and reflect some unpublished points of view about the genus structure.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)[1] with the following modifications:

  • A new globulinode group is created with the former Rhoptromyrmex species
  • A new decem group is defined following Hita-Garcia & Fischer (2014)[4]
  • weitzeckeri group structure follows Hita-Garcia et al (2010)[5]

Although Bolton (1980) consistently defined the species groups, additional research has led to some species being moved from their placement in 1980. The table here lists those changes.

Species Belongs to group Keyed in Reason
Tetramorium flabellum flabellum ericae, osiris, inezulae, gabonensis Branched pilosity
Tetramorium plumosum grassii ericae, osiris, inezulae, gabonensis Branched pilosity
Tetramorium rothschildi solidum ericae, osiris, inezulae, gabonensis Branched pilosity
Tetramorium pauper simillimum shiloense Small eyes

There are three species present. These species form a discrete species complex. Additional complexes in the tortuosum species group occur in other regions.
