Resumen en español

The species of Ormyridae that emerged of 15 from 65 gall morphotypes of Cynipidae in trees of the genus Quercus reported for Panama were studied. Specimens were collected from January 2008 to December 2010 in the cloud forests of the Cordillera Central of Panama. Three species of Ormyrus; O. hegeli, O. unifasciatipennis and O. venustus were identified parasitizing the gall inducers and inquiline species of the studied galls, with O. venustus being the most abundant species. This is the first report of O. hegeli from the Neotropics, a species which was previously recorded only from North America. The results extend the known distribution of this family of parasitoid wasps, and confirm the assumption that the lack of records of some groups of arthropods in Panamanian tropical forests is due to the lack of sampling rather than their absence.
