Galls on a leaf of Black Sage (Salvia mellifera, Lamiaceae)

Here are a pair of new galls on a leaf of native Black Sage (Salvia mellifera) in the Lamiaceae plant family. I believe they are the galls of a Sage Leaf Gall Midge (Rhopalomyia audibertiae) fly in the family Cecidomyiidae, Diptera. The galls look quite different above and below the leaf, and they are open on the end, with the opening filled with hairs - see this photo where this feature is more obvious. I find similar galls on native White Sage (Salvia apiana), see this photo. (San Marcos Pass, 22 February 2020)
