Although Kanturski, M. & Wieczorek, K. (2015). A new species of the nearctic gall-forming genus Tamalia Baker (Hemiptera: Aphididae: Tamaliinae). Zootaxa, 3926 (2), 268–278. https://doi.org/10.11646/zootaxa.3926.2.7 describe Tamalia milleri as associated with Arctostaphylos columbiana, further research is needed to determine whether it is indeed a gallformer and whether it is the only gallformer on A. columbiana. At present, galls on A. columbiana should be attributed to Tamalia sp.
