Identification
Radchenko and Elmes (2010) - A member of the pachei species group. It is characterized by the long, suboval head (CI > 1.20) with the convex sides and occipital margin, and the very widely rounded, barely marked occipital corners; margins of the head with not very abundant long suberect hairs. Its pronotum has coarse, short sinuous rugae and reticulation, while the mesonotal and propodeal dorsum has quite coarse transversal rugosity (numbering ≤ 20), similar rugae are also on the upper parts of mesopleura and propodeum. It differs from the related Myrmica weii by its distinctly higher petiole with a relatively short dorsal plate.
