The species differs from other representatives of this genus by projections on the trochanter IV. Material – Javakheti Highland ( N 41.291997 , E 43.532688 , 2036m a.s.l.), soil from artificial pine forest, one female, coll. Mumladze, L., 16.09.2018 ; Javakheti Highland ( N 41.36775901 , E 43.78562484 , 2106m a.s.l.), subalpine hay meadow, one female, coll. Mumladze, L., 16.09.2018 . Distribution in Caucasus – New for Georgia . Known from Russia – Akhun Mountain, Krasnodar territory, litter at decaying hornbeam ( Carpinus sp.) ( Bregetova 1977 ). Global distribution – Caucasus ( Bregetova 1977 ). Habitat – Decaying wood, litter, soil ( Bregetova 1977 ) Remarks In the original description, Black Sea coast of Georgia is indicated as an assumed distribution area along with type locality with no further details ( Bregetova 1977 ). Accordingly , we consider our finding as to the first geo-referenced occurrence of this species in Georgia .
