Key to Myrmica of East Europe, West Siberia, northern Kazakhstan, Caucasus, Asia Minor, Turkmenistan and Iran
This key is based on: Radchenko, A.G. & Elmes, G.W. 2010. Myrmica ants of the Old World. Fauna Mundi 3: 1-789. The first key is a key to workers.
This key does not include Myrmica karavajevi which is a worker-less social parasite living in nests of several Myrmica species. Its queens have well developed ventral process on the petiole, males have 12-segmented antennae, both queens and males are small: in queens HW < 0.90, AL < 1.40 mm, in males HW < 0.75, AL < l.30 mm. On forewing vein 2+3RS completely reduced and cells 1 +2r and rm are fused (Also see the Key for the socially parasitic species of West Europe).
