Feron scutellum (Weld, 1930), comb. nov.

Gall (Fig. 328). A cup-shaped leaf spangle gall, up to 4.5 mm in diameter and 3.5 mm high, purple-brown with a whitish bloom, attached to under side of leaf. The edge of the cup is thin, not in-rolled. The larval cell is 2 mm long by 0.7 mm in diameter and lies transversely at the very base of the cup. The exit hole is into the bottom of cup.

Biology. The asexual generation is only known, which induces galls on Q. gambelii (section Quercus, subsection Dumosae) and Q. turbinella (section Quercus, subsection Leucomexicana). Galls mature in late autumn, and adults were cut out from galls in December-January (Weld 1930).

Distribution. USA: AZ (Weld 1930).
