Nothing is known about the biology of Temnothorax artvinensis.

Identification

Csösz et al. (2015) - A member of the sordidulus species-complex. The very dark color of T. artvinensis prevents confusion of this species with any other Turkish Temnothorax treated in this revision.

Due to the fact that T. artvinensis is geographically well isolated from other dark brown or black species of the Temnothorax sordidulus complex, it is unlikely that this this species is confused with its siblings. However, for doubtful cases, or if anthropochory is suspected, a discriminant function after character reduction (D4 = +0.114_EL - 0.124_PEW +0.098_NOH -0.068_PPL +3.69209) separates 97.9% of T. artvinensis workers and each nest sample from that of Turkish Temnothorax schoedli and European brownish-black Temnothorax sordidulus and Temnothorax tergestinus.
