Feron kingi (agamic)

Andricus kingi n. sp.

Gall. — A broad, ovate, saucer-shaped base terminating in a small, slender cone with incurved sides. The point of the cone is open down to the flattened larval cell which lies close to the base of the gall. The surface is closely pubescent and of a smoky gray color. They are about one-'fourth* of an inch long and one-fifth in diameter across the widest part of the base or rim of the saucer. The leaves to which they are attached are those of Q. alba, I think.

Gall-flies. — Two females bred from galls sent me by Mr. E. H. King, of Napa City, Cal.

New Species of North American Cynipidae (1900)

Andricus kingi

Small, pink, cone-shaped galls on the underside of leaves of Quercus lobata, about 5mm. high and 4 mm. across the base, which is broad and rather saucer-shaped. The outer portion of the gall is conical, the sides curved inwards slightly. The larval chamber is near the apex, where the exit hole is found.

Status of Liodora dumosae and Andricus kingi

After some rearing experiments which yielded bisexual adults from galls identified as Liodora dumosae, Rosenthal and Koehler (1971) reached the conclusion that dumosae and Andricus kingi Bassett, 1900, were the alternate generations of a single species. Dailey has examined the material of Rosenthal and Koehler’s study (CIS) and found that they misidentified their wasp. The specimens are not dumosae, but are the previously unknown bisexual generation of kingi. The complete scutal notauli and short, straight tip of the galls distinguish the sexual form of kingi from that of dumosae. 

Nomenclatorial notes on North American Cynipidae (Hymenoptera)

Andricus kingi

The red, monothalamous, detachable, cone-shaped galls occur on both sides of the leaves of blue, valley, and Oregon oaks. The apex of the gall, although pointed, is blunt-tipped.
