Gall (Figs. 5a-c): It takes the shape of a cup located on the underside of leaves. The basal stem is uniformly cylindrical (about 3mm in length); the anchoring area or basal part is slightly wider; the cup-shaped body (10 mm in diameter x 8 mm in height) expands abruptly from the stem; the upper edges of the gall are thick, which makes it retain the circular edge. The color of the gall is yellowish-brown or reddish.

Hosts: Quercus laeta, Quercus magnoliifolia Née, 1801, Q. obtusata, and Quercus opaca Trelease, 1924 (section Quercus).

Biology: Only the asexual form is known. The galls develop in May-June; adults emerge in June and July.

Distribution: Cited from the states of Mexico City (including Sta. Fe on Q. laeta), Jalisco, and Mexico (Kinsey 1937a; Lobato-Vila et al. 2019; García-Martiñón et al. 2018).
