Druon fullawayi (Beutenmüller, 1913), comb. nov

Andricus fullawayi Beutenmüller, 1913: 244, female, gall

Gall (Figs. 31–32). Brown, elliptical, thin-walled, unilocular, with reticulate surface, covered with long soft
rusty brown woolly fibers. Gall 5–8 mm in diameter, found singly or in groups of two to many galls on the upper side of the leaf, along the midrib, cluster usually beginning at the base of the leaf. The long, soft hairs distinguish this gall from all other hairy leaf galls on white oaks.

Biology. Only the asexual generation is known, which induces leaf galls on Q. garryana, Q. douglasii, Q. lobata (Section Quercus, Series Dumosae). Galls do not dehisce from their host leaf, instead falling to the ground with the leaves in autumn; adults emerge in March of the following year.

Distribution. USA: California (Burks 1979) and Mexico: Zacatecas.
