Globular, often large galls found on Quercus turbinella buds. The galls are always located at the point where the leaf petioles connect to the stem, which often makes it appear that they are attached to the petioles. The galls are usually covered with small bumps and tiny hairs that are only visible upon close examination. They are usually red or green when developing and turn brown or tan with age. The walls are thick and with a spongy appearance when cross-sectioned, with two large cells located centrally. The galls are very similar to those of Nichollsiella arizonica, but adults are highly distinctive, and this undescribed species has only been confirmed from central New Mexico, where N. arizonica has yet to be documented. Adults emerge in mid-late March.
