Antron daileyi Lyon, new species

Range: El Paso cty TX

Host: Quercus pungens. Galls of this type were also seen on Q arizonica, grisea, and oblongifolia, but no wasps were reared from them.

Gall.--Fig 17. Monothalamous, thin-walled blisters that burst from cracks in the bark of twigs; galls are smooth, tan, 5-7 mm long. Adult females emerged 23-26 Mar and oviposited in unopened, dormant buds.

Xanthoteras pungens, new species

Host: Quercus pungens

Gall: Monothalamous and dome shaped, projected 3-5 mm from upper leaf surface; larval cells basal, with radiating filaments to wall. Adults mature and emerge from late December to mid-January.

Range: TX (El Paso County)

Andricus flocculentus Lyon, NEW SPECIES
(Figs. 18, 19) 

Gall. —(Figs. 18, 19).—Clustered, individual cells forming a woolly mass on the underside of the leaf midrib. Similar galls occur on other white oaks in the area, but no adults of A. flocculentus were reared from them.

Host.—Quercus pungens 


Antron madera Lyon, NEW SPECIES

Gall. —Monothalamous, spherical (Figs. 13, 14), small (3 mm diameter); attached to midrib on undersurface of leaf, flattened at point of attachment. Mature galls are slightly wrinkled and have scattered red and white microstellate hairs. The larval cell is centrally located and surrounded by thick nutritive layer that becomes spongy in older galls.
