The gall's range is computed from the range of all hosts that the gall occurs on. In some cases we have evidence that the gall does not occur across the full range of the hosts and we will remove these places from the range. For undescribed species we will show the expected range based on hosts plus where the galls have been observed.

New Western Gall Midges
EP Felt
(1916)
from ... leaf galls from Salvia (Ramona) californica and S. nivea [Felt later refers to "S. nivea (or leucophylla)"]
A very different leaf gall, apparently produced by the same midge, occurs on the margins of moderately well-developed leaves. It is a typical thin-walled, tubular gall with a length of about 6 mm., a diameter of 1.5 mm. The interior is occupied by an elongate larval chamber. Basally the gall is concolorous with the leaf, the distal third being purplish, the slightly curved apex a little lighter.
A modification of the first type of gall is seen on the aborted leaflets of S. nivea (or leucophylla). These galls are irregularly obconical, with a length of about 7 mm., a diameter of 3 mm. and are more or less confluent, otherwise nearly as described above.
