Synonyms

There are two queen forms, macrogynes and microgynes. The majority of colonies are monogynous with a macrogyne queen. The smaller number of polygynous nests typically contain microgynes but a small minority contain macrogynes (Schlick-Steiner et al., 2005). In Russia this species is found in more arid habitats than previously thought, where it is confined to the slopes on steppe-bordering forests (Zryanin & Zryanina, 2007).

Identification

Csösz, Radchenko and Schulz (2007) - Workers of T. moravicum are distinguishable from most species of the chefketi species complex (except for Tetramorium rhodium and Tetramorium syriacum) by their usually finely costulate scapes bearing a well visible and long dorsal carina basally. The most distinctive features, to separate T. moravicum from T. rhodium workers, the shape of the petiole in profile, and the relative length of scape; the frontal width gives appropriate discrimination of the workers of T. moravicum and T. syriacum.

Gynes of T. moravicum differ from known gynes of other species of the chefketi species complex by the relatively wide scutum, MW/CS 1.07 [1.05, 1.13] and by the dorsal carina of the scape.

Head nearly square, CL/CW 1.02 [0.97, 1.06], with very feebly convex sides, straight occipital margin and narrowly rounded occipital corners. Eyes small, EYE 0.170 [0.165, 0.183]. Frons moderately narrow, FR/CS 0.36 [0.34, 0.38], frontal lobes usually as wide as frons, rarely slightly wider, FL/FR 1.01 [1.0, 1.04]. Scape long, SL/CS 0.80 [0.77, 0.83], with well developed longitudinal dorsal carina basally, parallel costulae extending scape. Promesonotal dorsum slightly convex, metanotal groove deep. Propodeal teeth long. Petiolar node trapezoidal in profile, NOH/NOL 1.07 [0.90, 1.29], petiole relatively high, PEH/NOL 1.94 [1.72, 2.23]. General appearance coarsely rugoso-reticulate, ground surface microreticulate, dull. Head dorsum longitudinally rugose and microreticulate, occiput rugoso-reticulate. Alitrunk dorsum, mesopleuron and dorsum of petiolar node rugoso-reticulate, ground surface coarsely microreticulate, dorsum of postpetiole longitudinally rugulose and microreticulate. Polygonal striation continuous on 1st gastral tergite (see fig. 8.). Ventral surface of head with several short and few moderately long, straight, or few C-shape setae arising posteriorly to buccal cavity (see fig. 5).
