| Myrmica commarginata|
Inhabits steppes and dry meadows, often with sandy soil.
A member of the kasczenkoi complex of the lobicornis species group. Radchenko and Elmes (2010) - The mesonotum and propodeum of M. commarginata specimens are strongly constricted laterally, so that their dorsal surface is narrow and delineated laterally by sharp ridges, which merge with the outer bases of propodeal spines. This feature is not seen in any other known Myrmica species. We cannot exclude the possibility that such deformed individuals or perhaps naturally aberrant workers (even from several different species) have been included in the name M. commarginata. This will only be resolved when good consistent, colony samples containing queens and males are found. Except for the most unusual morphological feature after which it was named (see below) it is similar to sympatric lobicornis-group species, such as Myrmica kasczenkoi, Myrmica displicentia, or even Myrmica divergens. Furthermore, it appears to be unusually rare for a Siberian Myrmica species, having been found in only seven localities since its first description: Krasnoyarski Krai, Chitinskaya and Amurskaya Provo of Russia, and in Mongolia (Ruzsky 1925, 1936; Radchenko 1994f; Pfeiffer et al. 2007).
