Gnophos dumetata, the Irish annulet, is a species of moth in the family Geometridae. It is found in large parts of Europe (including West Russia and Ukraine), except Great Britain, Portugal, the Benelux, Switzerland, Bulgaria, Fennoscandia and the Baltic region. It is also found from north-western Africa to Armenia, Dagestan, and the south-western part of the former Soviet Union.
The wingspan is 24–28 mm. The upperside of the wings is light chocolate-brown, slightly tending to yellow. The outer marginal area is darker brown. "Larger than stevenaria (Gnopharmia stevenaria), more brownish, with less enlarged costal spots, upperside usually with conspicuous discal dots, that of the forewing sometimes lost in the median shade. Underside without darkened distal area, postmedian line usually indicated by vein-dots."
Adults are on wing in August.
The larvae feed on Rhamnus catharticus.
