Syntype Specimen Label


An ant of dry regions that nests in wet places such as salt marshes, bogs, and along the banks of watercourses.


Radchenko and Elmes (2010) - A member of the bergi complex of the scabrinodis species group that is most similar to Myrmica gallienii, differing from the latter by the shorter propodeal spines, lower petiole, darker colour, etc.; males differ by relatively longer scape.

Although M. bergi is distributed in semi-arid and even arid regions, within these it dwells exclusively in intrazonal, damp and almost always salted habitats, where it can be very abundant locally. Arnoldi (1934: 161) states that it is "Characteristic for salty bogs". The populations of M. bergi from the steppe zone of southern Ukraine have been most studied (Bondar et al. 1998; Bondar 1999; Bondar, Rusina 2003; Stukalyuk, Radchenko 2008, and personal observations). Here it nests in the reed, sedge and grass associations that border the sea shore (salt marshes and lagoon shores) and surround the numerous salted lakes of differing sizes. Around salted lakes workers can be seen foraging over the caustic encrusted, white, salty deposits even in full sunshine. Nests are built shallowly in the soil but almost always have a large mound of soil above them in which the majority of ants live. Usually the mound is constructed around plant stalks, especially sedges, and in times of flooding the entire colony migrates up the stems where it can construct temporary nest high above the water level, covered with soil and pieces of vegetation (Bondar et ai. 1998), and the foraging workers actively swim, sometimes for several tens of meters. The other studies cited above have shown that colonies can be large and polygynous, containing several thousand workers, and in optimal conditions they can be polycalic comprising several tens of nests. Possibly this may be a local adaptation to high relatedness, it being probably that populations living around isolated lakes are quite inbred. We have seen small colonies nesting more typically in the soil (for scabrinodis-group.species), living in competition with other ant species in short moist, grazed grassland on the raised banks of the river Dnepr where flooding is less likely.

Tarbinsky (1976) studied M. bergi living in Kirgizia; he wrote (lac. cit., p. 46) that it "Lives up to altitude 1600 m, along river and stream banks, near Salix and Hippophae shrubs, or near Phragmites, in semi-shaded places. It nests in sandy soil, sometimes with small mounds, but usually without them. In the morning and evening ants forage on open sand but during the day, in shade under shrubs or Phragmites". In this respect it is quite similar to the Ukrainian populations. However, Tarbinsky (lac. cit.) also said that colonies are "quite large compared to other Myrmica species" (which agrees with our observations) "and monogynous" which is atypical for south Ukrainian populations. Ruzsky (1905) recorded that var. 'barchanica nested in sandy soils with rich vegetation, mainly Populus and Salix.

Radchenko and Elmes (2010) - this species was named for its collector, Prof. Lev Semenovich Berg, who was a distinguished Russian natural scientist, most famous for his work on marine biology and the theory of nomogenesis (the initials H. L. Berg in Ruzsky 1902b probably means "Herr L. Berg").
