Druon receptum Kinsey, 1937, comb. rev.

Druon receptum Kinsey, 1937: 62, female, gall.
Andricus receptum (Kinsey): Weld (1952a)

Gall (Fig. 209). Greyish yellow-brown wool covering a cluster of 4 to 8 larval cells (Kinsey 1937). Pubescence darkens with age; the individual hairs are very long, considerably tangled, completely hiding the larval cells. The individual clusters are rounded to oval, dense but fluffy, averaging nearly 20 mm in diameter and 12 mm in height. Several individual clusters can be fused into large, elongate masses up to 35 mm long. Mature larval cells are over 3.5 mm long on average, rather robustly elongate (Kinsey 1937).

Biology. Only the asexual generation is known, which induces galls on Q. rugosa (= Q. rhodophlebia) and Q. potosina (both Section Quercus, Series Leucomexicanae) in Mexico; Q. rugosa in Arizona. Galls mature in late autumn; adults emerge from February of the following year, most emerging in March–April.

Distribution. USA: Arizona, Santa Catalina Mtns. Mexico: Guanajuato, Mexico City, Querétaro, State of Mexico, Zacatecas.
