Identification

Csösz, Radchenko and Schulz (2007) - A member of the Tetramorium chefketi species complex in the Tetramorium caespitum species group.

Workers of T. anatolicum can be separated from related species by the lack of psammophore, relatively small eyes, moderately long and smooth scape, without a dorsal carina basally, relatively fine and parallel body sculpture and trapezoidal petiolar node. Workers of T. anatolicum are mostly similar to Tetramorium exile, but differs by its relatively shorter scape and somewhat wider frons. Discriminant D(2a) function proves the separation between T. anatolicum and T. exile (see differential diagnosis of T .exile). Workers of T. anatolicum may look similar to those of Tetramorium chefketi, but can be distinguished by their lighter colour and shape of petiolar node: in T. anatolicum it is relatively high and short, trapezoidal, in profile, while in T. chefketi it is relatively low and longer, cubic in profile. Discriminant D(3a) function proves the separation between T. anatolicum and T. chefketi (see differential diagnosis of T .exile).

Gynes of T. anatolicum can be distinguished by the lack of psammophore, moderately long, smooth scape, without a dorsal carina basally, wide scutum, relatively narrow petiole and postpetiole, and partly smooth katepisternum.

Polygonal striation disrupted on 1st gastral tergite, sometimes continuous basally. Ventral surface of head with several short and few longer, straight or “C”-shape setae, arising posterior to buccal cavity.
