description: Definition of chefketi species complex
Species belonging to the T. chefketi species complex can be defined by the following combination of characters:
Workers
a) polygonal striae are continuous on 1st gastral tergite, and is sometimes microreticulate basally. Polygonal striation: interstices marked by feeble anastomosing striae (Fig. 8.), compare to microreticulation: interstices marked by very feeble elevated structures, like rugulae (Fig. 6, 7.);
b) head, alitrunk and waist coarsely sculptured, dorsum of petiolar node and postpetiole coarsely rugose and/ or reticulate.
c) petiole and postpetiole relatively narrow (CS/PEW and CS/PPW, Table 1);
d) ground surface on the frons is usually coarsely microreticulate;
Gynes
e) alitrunk is low, dorsum is flattened in profile;
f) scutum in dorsal view is somewhat narrowed anteriorly and does not cover completely the pronotum, humeri are well visible;
g) head, alitrunk and waist are coarsely sculptured, and petiole and postpetiole dorsum coarsely rugose or/ and reticulate;
h) polygonal striae disrupted on 1st first gastral tergite, sometimes microreticulate basally;
i) mandibles are longitudinally striate;
j) petiole and postpetiole are relatively narrow (WAIST, Table 2);
Males
k) head and alitrunk with usually coarsely sculpture, ground surface microreticulate; l) sides of petiole and postpetiole not angulate as in the ferox species complex (in dorsal view); m) first gastral tergite usually smooth and shiny, or feebly striate;
n) stipes of genitalia blunt, curved inwards at the top, with flattened apical plate (in caudal view);
We placed the following species into the chefketi species complex:
1) Tetramorium alternans Santschi, 1929
Tetramorium biskrensis kahenae Menozzi, 1934 new synonymy
2) Tetramorium anatolicum Csősz & Schulz, new species 3) Tetramorium annectens Pisarski, 1969 status revised
alternans anatolicum annectens chefketi moravicum sanetrai sulcinode (n=5) (n=3) (n=1) (n=11) (n=12) (n=3) (n=3) 4) Tetramorium chefketi Forel, 1911
Tetramorium caespitum var. sarkissiani Forel, 1911 new synonymy Tetramorium turcomanicum Santschi, 1921 new synonymy Tetramorium taurocaucasicum Arnoldi, 1968 new synonymy Tetramorium forte Forel, 1904 [in part, only material from Crimea and Caucasus] (for details of
clarification of synonymy see Taxonomic notes under Tetramorium chefketi)
5) Tetramorium exile Csősz & Radchenko, new species
6) Tetramorium moravicum Kratochvíl, 1941
Tetramorium rhenanum Schulz, 1996
7) Tetramorium rhodium Emery, 1922 status revised
8) Tetramorium sanetrai Schulz & Csősz, new species
9) Tetramorium sulcinode Santschi, 1927 status revised
Tetramorium karakalense Dlussky & Zabelin, 1985 new synonymy
10) Tetramorium syriacum Emery, 1922
The newly defined chefketi species complex may not strictly reflect the phylogenetic relationship of the above­mentioned species. T. sulcinode and T. annectens possess several autapomorphic characters (e.g. relatively large eyes and a long psammophore) what probably may lead to place them into a separate group in a future.
