Andricus incomptus, new species

Host: Quercus sp [Quercus grisea added as a placeholder]

Gall.--A mass of golden brown, straggling wool, containing a spherical core which is set with a dense, rich reddish-brown pubescence. Monothalamous. The covering hairs are 5 mm or more in length, brittle, and rather wavy, forming an "uncombed" mass about 15 mm in diameter. The central core is spherical, averaging 7 mm in diameter, and is covered with a very dense pubescence of dark reddish-brown hairs less than 1 mm long; this covering is quite distinct from the longer, fewer hairs which form the main covering of the gall. The walls of the central core are almost 1 mm in thickness, and the rest of the core is taken up with the large larval cell. Singly, or more often in groups of two, on the under surfaces (less often on the upper surfaces) of the leaves of a species of Quercus.

The gall is very distinct.

Range: Mexico, San Luis, Potosi
