keys that were used (Buhr, 1965; Eady & Quinlan, 1963; Nieves-Aldrey, 2001; Redfern & Shirley, 2011a; Roskam, 2009; Williams, 2010a) pointed to Andricus glandulae; however, without exception all keys describe the gall of that species as oval. That is in agreement with a picture in Bloxham (2004a), showing a gall that somewhat reminds of A. solitarius.

The gall most closely agrees with the drawings of the gall of Neuroterus politus in Redfern & Shirley and Roskam. However, that picture so strongly deviates from what is illustrated by Melika ao under that name that the identification is doubtful.
