The ant genus Tetramorium Mayr in the Afrotropical region (Hymenoptera, Formicidae, Myrmicinae): synonymisation of Decamorium Forel under Tetramorium, and taxonomic revision of the T. decem species group.

Hita Garcia F, Fisher BL - Zookeys (2014)

Bottom Line: In this study we synonymise the genus Decamorium Forel under Tetramorium Mayr, revise the new T. decem species group by providing a diagnosis of the group, an illustrated identification key to species level, and worker-based species descriptions for all five species, which include diagnoses, discussions, images, and distribution maps.The following species are revised in this study: T. decem Forel, comb. r., T. raptor sp. n., T. uelense Santschi, comb. r., T. ultor Forel, comb. r., stat. r. & stat. n., and T. venator sp. n.In addition, we also designate lectotypes for T. decem, T. uelense, and T. ultor.

Mentions: The Tetramorium decem species group is endemic to the Afrotropical region where it is widely distributed (Fig. 3). Tetramorium raptor and Tetramorium uelense are found in West and Central Africa and Tetramorium venator occurs through most of the equatorial rainforest belt from Liberia in West Africa to Western Kenya. By contrast, Tetramorium decem and Tetramorium ultor are species from eastern and southeastern Africa. Surprisingly, the group seems to be absent from South Africa based on the material available to us, but Tetramorium decem or Tetramorium ultor are likely to be found there or in neighbouring Botswana or Namibia. Furthermore, we expect the distribution ranges of Tetramorium decem, Tetramorium uelense, and perhaps Tetramorium ultor to expand with further ant inventory or collecting projects in Afrotropical savannahs, dry forests, and other arid habitats. These were sparsely sampled in sub-Saharan Africa in the past since most modern ant inventories have focused on rainforests (e.g. Belshaw and Bolton 1994; Watt et al. 2002; Fisher 2004; Yanoviak et al. 2007; Hita Garcia et al. 2009), whereas only a few studies have examined ant faunas from drier localities (e.g. Robertson 1999, 2002; Braet and Taylor 2008).
