Neuroterus verrucum Pujade-Villar, In Pujade-Villar et al. (2014b: 6)

Gall (Figs. 6j-l): Cryptic galls located on the surface of the bark of the previous year's shoots. They are very discreet, hard to recognize without the emerging holes of adults. They are solitary or in groups of up to 5 larval chambers (1.1 x 0.5 mm). Externally, they are seen as small surface warts on the bark; the yellowish larval chamber is surrounded by a thin brown woody tissue.

Hosts: Quercus laeta (section Quercus).

Biology: Species is known only from the asexual generation. Adults emerge at the end of winter and beginning of spring when new shoots start to grow.

Distribution: Only known from Santa Fe (Mexico City).
