Agamic female

[Photos of this gall appear on page 9 of the pdf]

[Galls: Monolocular grown from a deformation of a bud. Spherical (2-4 cm in diameter), often tapered and weakly stalked. The surface is rough, with large number of protruding bumps. At first from green to be brown clear at maturity. Hard consistency. Transverse cross sections show the lignified central larval chamber (3 mm diameter + 1 mm thick internal gall wall) surrounded by dense spongy tissue.]

Hosts: Quercus crassipes

Distribution: Mexico City

Biology. Species known only from the agamic generation. Adults emerge in mid-May. These galls are frequently attacked by inquilines that are found in the larval chamber, greatly increasing its size and dividing it into compartments (Fig. 4c). The inquiline species is Synergus striatifrons Pujade-Villar and Lobato-Vila; the host of the Synergus obtained from Amphibolips sp (MEX-299) mentioned in Lobato-Vila & Pujade-Villar (2017), corresponds to A. cibriani n. sp
