Neuroterus eugeros (agamic)

Neuroterus fusifex (sexgen)

Neuroterus eugeros Pujade-Villar n. sp.

Galls (Figs. 1b). Plurilocular (probably due to being fused unilocular), located on the underside of the leaves between the secondary nervations, inseparable from the leaf tissue, they are almost always found touching the leaf margin. Their presence causes the appearance of a very abundant trichose silkiness. The lower side is visibly swollen, up to 1.5 cm thick, the upper side is not. The leaf dries and wrinkles where the galls are present, so that when they are very abundant the oak looks sickly. Adults emerge from the upper side.

Host. Quercus laeta Liebm. (section Quercus). Species endemic to Mexico. Present in multiple states (Valencia-A, 2004).

Distribution. Mexico (Mexico City)
