Eriophyes prunianus Nalepa, 1926

Host plant records from Latvia: Prunus domestica L. ( Rosaceae ).

Description of galls: Mites cause small (up to 2 mm) pubescent galls of light green or reddish coloration on the upper side of leaves ( Fig. 1C ).

Records in Latvia: DUBD-0001013, 24.06.2021, 56.42495264102208, 26.942195972159556, Pustinka, Silmala Parish, Rēzekne Municipality .

Distribution in the world: Belarus ( Petrov 2021), France, Germany, Poland, Russia (GBIF. org 2023c).

In addition, on willows ( Salix caprea L. and Salix cinerea L., ( Salicaceae )) large galls (up to 5 cm) were recorded. These galls represent modified, significantly thickened lateral shoots or male and female buds with highly shortened scale-like leaves ( Fig. 1D ). It can be assumed that the formation of such galls is initiated by Stenacis triradiatus (Nalepa, 1892) , which have been previously reported to Latvia as Eriophyes triradiatus Nal. ( Cinovskis 1979), but later it was not mentioned in other publications.
