Three new ant species are described form the North Caucasus (Russia): Temnothorax dlusskyi sp. n., T. arnoldii Radchenko et Fedoseeva, sp. n., and T. tembotovi Radchenko et Yusupov, sp. n. Temnothorax dlusskyi sp. n. is characterized by the long head, the low and long mesosoma without metanotal groove, by propodeum without teeth; the head dorsum is densely punctated and longitudinally rugulose, mesosoma is coarsely longitudinally rugose; body is reddish-brown, head is darker; 1st  gastral tergite is completely brownish, without lighter spot at the base. Temnothorax arnoldii sp.  n. is characterizes by the long head, the low and long mesosoma without metanotal groove, propodeum with very short but distinct, acute triangular teeth; the head dorsum with dense straight longitudinal rugulosity and punctation; mesosoma laterally and pronotal dorsum with coarse longitudinal sinuous rugae; mesosoma and waist are reddish-brown, head dorsum is dark brown; 1st gastral tergite is brownish, its base a little lighter. Temnothorax tembotovi sp.  n. is characterized by the long head; mesosoma of moderate length, without metanotal groove, propodeum with teeth or spines of various length, they are almost straight and slightly widened at the base; head dorsum is densely punctated, appears dull, the fine longitudinal rugulosity or striation may be developed on frons; mesosoma and waist are densely punctated, appears dull; mesosoma and waist are dark-yellow to ochreous-yellow, the head dorsum somewhat darker, 1st gastral tergite is bright yellow, with brownish band posteriorly. Taxonomic position of Temnothorax alpinus and T. korbi are reassessed; the name T. werneri is considered as a junior synonym of T. alpinus; T. korbi is transferred to the corticalis species group.
