Radchenko and Elmes (2010) - M. displicentia prefers well insolated and warm habitats such as roadsides, open slopes, glades, forest clearing, etc. where it builds nests in the soil, often under stones (see Kupyanskaya 1986b, 1990; Berman et al. 2010). Colonies examined comprise a few hundreds to 1500 workers with a maximum of 3 queens. Everywhere it is quite a rare species. Gynes and males were observed in June-August.
Radchenko and Elmes (2010) – A member of the kasczenkoi complex of the lobicornis species group that is characterized by the strongly curved (not angled) bend at the base of the scape that has no vertical lobe or dent. By this feature it is similar to some other species form this group (e.g. Myrmica sulcinodis, Myrmica ademonia or Myrmica kasczenkoi), but differs from them by its distinctly bicoloured body, with the yellowish-red alitrunk, contrasting with much darker head and gaster; additionally, M. displicentia well differs from M. sulcinodis by its much less coarse sculpture and by the shape of its petiole.

Radchenko and Elmes (2010) - the Latin word displicentia means dissatisfaction or discontent. We are not sure whether B. Bolton intended this or whether he made-up a word from the English di (two) and spliced (joined together) to represent the bicoloured body.
