M. slovaca is a rather thermophilous species that builds its nests directly into the soil. In central Europe it is frequently found in dry meadows but in the eastern part of its range, M. slovaca mainly inhabits intrazonal, relatively wet and often salted habitats in the steppe zone. Thus it could be a relict steppe species in central Europe. (Radchenko and Elmes 2010)


Radchenko and Elmes (2010) - A member of the specioides complex of the scabrinodis species group. It is easily distinguished from any other species from this group by its very narrow frons (worker PI ::; 0.30). However, the males have short standing hairs on the legs and scape and are hard to distinguish from males of Myrmica specioides and some other species.

Type Material

Bezděčková et al. (2017) - Myrmica slovaca: Altogether 11 syntypes are deposited in National Museum, Prague, Czech Republic (all dry-mounted, glued on rectangular card labels):

  • SYNTYPES (4 workers glued on two labels (3 + 1) on one pin): ‘Chorovce / 1.6.48 / Slovakia / Novák [hw] // M. slovaca / Sadil (det. 1951) [hw] // Mus. Nat. Pragae Inv [p] / 3066 [hw]’.
  • SYNTYPES (7 workers glued on one label with transversal yellow line and number 3108, hw): ‘Slov. Dol. Almáš / 1938, Záleský lg. [p] // Det. Dr. Záleský [p] / M. scabr. [worker symbol] / scabrin. [hw] // M. slovaca / Sadil (det. 1951) [hw] // Mus. Nat. Pragae Inv [p] / 3068 [hw]’.

Remarks: Because of the widespread use of M. slovaca and doubts about the origin of the holotype specimen of M. curvithorax, RADCHENKO & ELMES (2010: 281–282) stated that they would apply to the International Commission on Zoological Nomenclature with the proposition to suppress the name M. curvithorax and consider M. slovaca the valid name (based on Articles, and 23.9.2 of ICZN 1999). However, this application has not been done yet.
