Specimen Labels


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).


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.
