Galls like the ones illustrated above are attributed in the literature alternately to Aceria convolvuli and Acululus convolvuli. The Aceria galls would be hairless, but that does not seem a reliable character. Also a third species, viz. Aceria malherbae, is reported to cause identical galls. Because in actual practice the galls cannot be named by an identification of the responsible gall mites, they are lumped here, in accordance with Redfern & Shirley, under Aculus convolvuli.
