Florida Entomologist 85 (4), 625-631
Abstract: The alternate, sexual generation of Callirhytis quercuscornigera (Osten Sacken), comb. rev. was found by experimental rearing and field observations. Descriptions of the adult, gall, biology, and host plants of the sexual generation are given. A new species of cynipid inquiline, Ceroptres cornigera Melika and Buss, reared from galls of the sexual and asexual generations of Callirhytis quercuscornigera (Osten Sacken) of the eastern United States is also described and illustrated. This is the first known species of Ceroptres to inhabit galls from alternating generations of its host cynipid. Descriptive data, diagnostic characters, distribution, and biological information are given.

Por observaciones de campo y cría experimental, se descubrió la generación alterna sexual de Callirhytis quercuscornigera (Osten Sacken), combinación revisada. Se describen el adulto, la agalla, el desarrollo y las plantas huesped de esta generación sexual. Se describe e ilustra también una especie nueva de cynipido inquilino, Ceroptres cornigera Melika y Buss, críada de las agallas producidas por las generaciones sexuales y asexuales de Callirhytis quercuscornigera en el este de los Estados Unidos. Esta es la primera especie de Ceroptres descrita que habita las agallas de ambas generaciones de su huesped. Se presentan datos, caracteres descriptivos, distribución e información biológica.
