Redescription of Tetramorium forte Forel, 1904 (Insecta: Hymenoptera: Formicidae), a western Mediterranean ant species. Author Güsten, R. Author Schulz, A. Author Sanetra, M. text Zootaxa 2006 1310 1 35 http://antbase.org/ants/publications/21095/21095.pdf journal article 21095 B17A7DB9-DBB5-4E56-B313-0A202A75BFAC Tetramorium chefketi Forel , 1911 Tetramorium caespitum var. chefketi Forel , 1911 Tetramorium chefketi Forel : Agosti & Collingwood 1987a, 1987b According to Agosti and Collingwood (1987a), the species (misspelled “chefteki”), which was described from the European part of Turkey, occurs also in Greece and Anatolia. We compared specimens from these areas with the worker syntypes (MHNG) and support this view. Schulz (1996) presented characters differentiating T. chefketi from the closely similar T. moravicum and T. forte , and Sanetra and Buschinger (2000) as well as Schlick-Steiner et al. (2005) studied its phylogenetic position in relation to T. forte , T. moravicum and T. semilaeve . Csoesz et al. (unpubl.) ascribe the paralectotypes of T. forte from Alušta ( Crimea , Ukraine ) to T. caespitum sarkissiani Forel , 1911 and regard that taxon as synonymous to T. chefketi , which has equal priority.
