The inquiline oak gall wasp fauna emerged from agamic galls of Andricus quercuslaurinus Melika and Pujade-Villar, 2009, a dangerous pest for Quercus affinis Scheidw. and Q. laurina Humb. et Bonpl. forests in Mexico, was studied for the first time. Three species in the genus Synergus Hartig, 1840 (Synergini) were obtained from these galls: Synergus davisi (Beutenmüller, 1907), previously known only from the United States of America; Synergus estradae Pujade-Villar and Lobato-Vila, 2016, described from the state of Morelos (Mexico); and Synergus pseudofilicornis Lobato-Vila and Pujade-Villar n. sp., so far determined as Synergus filicornis Cameron, 1883 (= Synergus furnessana Weld, 1913) and here considered as a new species. Synergus pseudofilicornis n. sp. is described and illustrated. A redescription and photographs of S. davisi, as well as new distributions and host associations of S. davisi and S. estradae, are given. The value of the inquilines as biological control agents for A. quercuslaurinus is discussed, and a preliminary list of parasitoids obtained from the galls is presented.
