Amphibolips kinseyi, sp. nov.

Gall: The gall is similar to the gall of Amphibolips dampfi described by Kinsey (1937). A moderate to large “oak apple”, irregularly spherical gall with spongy inner consistency. They are light green without spots when they are fresh and light brown when they are dry. The epidermis is thin, at 0.4 mm thick; firmly attached to the internal spongy tissue when fresh; firm and brittle when dry. The consistency is relatively hard and fleshy when green and brittle when dry. The consistency is relatively hard and fleshy when green and brittle when dry. Internally, the spongy tissue occupies the entire space between the epidermis and the larval chamber (Fig. 8F). Diameter of 30 mm and height of 31 mm on average (diameter of 16 to 44 mm and height of 18 to 51 mm; n = 18). Rigid and oval larval cell, 0.4 mm thick and 6.5 mm long × 5 mm in diameter on average (n = 2). Galls are formed on the twigs of Quercus zempoaltepecana Trel. Galls are relatively common in the study area.

Distribution. Known only from the type locality along the route from Ixtlán to Tepanzacoalcos (Oaxaca State, Mexico).

Biology. Sexual generation. The galls were collected in late April and the insects emerged shortly thereafter, in early May. It is normal to find galls deformed and/or attacked by inquilines and parasitoids; the deformed or attacked galls are usually relatively small.
