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).

Galls (Fig. 3)

Located on the underside of the leaves in large numbers, between the secondary or tertiary veins, rarely on top of them. They are strongly attached to the leaf surface without producing a sinking of the leaf at the point of insertion. They are globular with a flat base, brown on the side and light in the apical zone, with a whitish apical pubescent tuft.. The surface is shiny and alutaceous, sometimes with some weak longitudinal carinae.
The diameter is 1.5-1.6 mm and the height is 1.2-1.3 mm. The larval chamber is located in the lower part of the gall parallel to the leaf (1.2 × 0.5 mm); above it there is a hard tissue that protects the larval chamber above the gall (1.2 × 0.5 mm).

Host
Quercus rugosa Née (section Quercus). Species widely distributed in Mexico (in the states of Aguascalientes, Baja California, Chihuahua, Coahuila, DF, Durango, Guanajuato, Hidalgo, Jalisco, Mexico, Michoacan, Oaxaca, Sinaloa, Puebla, San Luis Potosí, Sonora, Tamaulipas, Tlaxcala, Veracruz, Zacatecas); also present in southern Arizona and Guatemala.

Distribution
Mexico (Mexico City and Tlaxcala).

Biology
Species known only from asexual generation. The adults emerge from the end of June to the end of July; galls are not deciduous. This oak is not deciduous, the replacement of the replacement of the previous year's leaves is done gradually.
