Feron comatum (Weld, 1952), comb. nov.

Gall (Figs 122–123). Conical, 3.0 by 1.4 mm, tan when mature, thin walled, covered with crinkly white matted hairs. Produced singly at edge of leaf. The gall is difficult to distinguish from the sexual galls of F. crystallinum, F. dumosae and F. kingi, although this species has an eastern distribution rather than Pacific slope (but see also diagnosis to species above).

Biology. Only the sexual generation is known, inducing galls on Q. alba (section Quercus, subsection Albae). Galls mature in early spring; adults emerge in late April–May.

Distribution. USA: VA (Weld 1952b).

Liodora comata

Quercus alba
Leaf galls, integral

"Like Liodora comata"

Quercus stellata

On Q alba. Gall similar to above [N clarkeae]. Adults emerged May 4, 10, 12, 14 (DC).

316. Similar to Neuroterus clarkeae. above but pointed at end, 3 by 1.2 mm and covered with crinkly white hairs, tan, thin-walled, at edge of leaf of Q alba in early spring.

Liodora comata, new species

Host.--Quercus alba

Gall (pl. 16, fig. 11). — Conical, 3.0 by 1.4 mm., tan, thin walled, covered with crinkly white matted hairs. Produced singly at edge of leaf in early spring when leaves are only an inch or so long.

Habitat. — Type locality East Falls Church, Va. Adults emerged April 26 and May 4-15.

Andricus comata

Consequently, three Liodora species known from North America must be transferred to Andricus: comata (Weld), comb. nov.
