ARMENIA: Aragatsotn, Mt Aragats , 40°29’N 44°11’E, 3505 m, by snow field, 18.vii.2018 (A.C. Pont), 10♂ 6♀ ; same locality, 3285–3500 m, 18.vii.2018, 2♂ 2♀ ; same locality, 3285 m, on Ranunculus aragazi , 19.vii.2018, 1♂ ; same locality, 3285 m, sweeping over Campanula tridentata , 18.vii.2018, 1♀ .

D. setibasis is a rare species in Armenia and was previously found only in Aragatsotn province at Lake Kari and on Mt Aragats, from 3190 to 3560 m ( Pont 2018: 15). It is clearly a high-altitude species in both Armenia and Georgia, occurring well above the tree-line.
