Andricus chiricahuensis Melika, Nicholls & Stone, sp. nov.

Diagnosis. Type material of this species was obtained from a mixed rearing of galls of this species and Neuroterus stonei. Hence exact details of the gall are unknown, but it is probably a small round bud gall, easily confusable with the gall induced by N. stonei (Fig. 434) and the sexual generation of the closely-related species Andricus coconinoensis (Fig. 88).

Gall. This species definitely induces bud galls on Q. gambelii, but we do not yet know the exact details of gall structure or appearance. It is most likely a globular, smooth gall, either greenish or pale brown.

Biology. Only a sexual generation is known, which induces bud galls on Q. gambelii; adults emerge in April.

Distribution. USA, Arizona, Chiricahua Mountains.
