The gall's range is computed from the range of all hosts that the gall occurs on. In some cases we have evidence that the gall does not occur across the full range of the hosts and we will remove these places from the range. For undescribed species we will show the expected range based on hosts plus where the galls have been observed.

Cynips q. virens n. sp.
Quercus virens [Quercus virginiana]
Galls.--Small, globular, the size of a pea or slightly larger; from two to ten, attached to the underside of the leaf; pale brownish in color, filled inside with a dense, yellowish-brown, spongy, cellular mass. A single kernel in the centre. Diameter 0.15 to 0.25 inch.
Issued from the gall early in February.
[Weld cites this as the original description of his Disholcaspis virens, but it does not match his description (a stem gall) and seems to instead describe what was later renamed Belonocnema quercusvirens, which is now a species inquirenda likely referring to Belonocnema fossoria.]
