Neuroterus acrotrichias Pujade-Villar, In Pujade-Villar et al. (2017a: 68)
Gall (Figs. 6d-e): Located on the underside of the leaves in a high number, between the secondary or tertiary veins, rarely on top of them. They are strongly attached to the leaf surface without causing a depression of the leaf at the point of insertion. They are not deciduous. They are globular with a flat base, chestnut-colored on the side and light in the apical area, provided with a whitish apical pubescent tuft. The surface is shiny and leathery, sometimes with some weak longitudinal ridges. The diameter is 1.5-1.6 mm and the height is 1.2-1.3 mm. The larval chamber is located at the bottom of the gall parallel to the leaf (1.2 x 0.5 mm); above it, there is a hard tissue that protects the larval chamber from above.
Hosts: Quercus rugosa (section Quercus).
Biology: Species known only for the asexual generation. The galls begin their formation at the end of winter. Adults emerge at the end of June.
Distribution: Mexico (Mexico City, Mexico, and Tlaxcala); cited from Santa Fe in Pujade-Villar et al. (2017a).
