Myrmica kozlovi

Poorly known. M. kozlovi has been found at the highest altitudes recorded for any Myrmica species worldwide (4800 m) which probably accounts for it being the only Myrmica species that has crossed the Himalayan barrier to live on both the western and eastern slopes. Donisthorpe (1929) wrote that “According to Major Higston [the collector of Myrmica specularis, a junior synonym] the ants found at the higher elevations [in the Himalaya] are exceedingly lethargic and sluggish in their movements.” (Radchenko and Elmes 2010; Bharti et al., 2016)

Identification
A member of the kurokii group.

Distribution
M. kozlovi is probably widespread in the Himalayn mountain system and isolated populations predictably can morphologically vary.

Distribution based on Regional Taxon Lists
Oriental Region: India, Nepal, Tibet. Palaearctic Region: China.
