References: COGOLLUDO (1921, on Salix repens L. var. argentea Koch), TAVARES (1924). – Note. According to the host plant species, the causer of the swellings is probably the species Rabdophaga schicki Stelter, 1982, which was described on adults reared from Salix repens L. ssp. rosmarinifolia in Germany (STELTER, 1982, 1993).
