Zapatella cryptica
(Weld) comb. n.

Callirhytis cryptica Weld, 1922b (female, galls).

Only the asexual generation is known. It induces bud galls on Quercus myrtifolia Willd. and Quercus falcata Michx. in the USA (Florida and Alabama) (Weld 1922b, Burks 1979).

Type galls were collected in October and adults emerged the next year in May (Weld 1922). The affected terminal bud cluster becomes enlarged, one or two green leaves sometimes grow out beyond the bud scales, and later the bud turns brown; the gall is completely hidden within the bud and is conical, with a thin-walled cell and a tuft of hairs near the apex (Weld 1922b).
