Abstract
A review of the inquiline oak gall wasp species of the genus Synergus Hartig that are known to be associated with Cynipini woolly galls on oaks (Quercus L.) from the New World is conducted for the first time. Redescriptions, remarks, pictures and/or new location and biological data for the species previously known from the New World are given. Comments on morphological variability and host associations of different species, and especially that of S. pseudofilicomis Lobato-Vila and Pujade-Villar, 2018, are also provided. A new species that emerged from galls collected in Mexico is formally described and illustrated: Synergus forcadellae Lobato-Vila and Pujade-Villar, new species. An identification key to all the species addressed in this work is provided. Synergus niger Fullaway, 1911 is considered a new synonym of S. citriformis (Ashmead, 1885), and S. similis Gillette, 1896 a new synonym of S. filicomis Cameron, 1883.
