Morphometrics: (108 workers and 12 gynes measured).

Diagnosis. Workers of T. moravicum are distinguishable from most species of the chefketi species complex (except for T. rhodium and T. 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 (NOH/NOL, PEH/NOL, Table 1 .), and the relative length of scape (SL/CS, Table 1 .); the frontal width (FR/CS, Table 1 .) 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.

For further combination of morphometric characters see Table 1–2 .

Distribution. Widespread in the western Palaearctic from S France to Caucasus. The westernmost known locality of this species is Camargue, France.
