Synergus pseudofilicornis Lobato-Vila & Pujade-Villar, 2018

Synergus pseudofilicornis Lobato-Vila & Pujade-Villar in Lobato-Vila et al. (2018) . Southwest. Entomol. 43 (3): 600. Type material: UB (holotype), paratypes in UB , UACh, and USNM.

Diagnosis. See Lobato-Vila et al. (2020b: 703) and the diagnoses of S. diversicolor and S. weldi , sp. nov. (this work).

Distribution. Mexico: Ciudad de México, Hidalgo, México, Morelos, Nuevo León, Puebla, Tlaxcala, and Veracruz (Lobato-Vila et al. 2018, 2019, 2020b).

Biology. Synergus pseudofilicornis is considered a generalist species, even though it is more frequently reared from asexual tuberous twig galls of Andricus quercuslaurinus Melika & Pujade-Villar, 2009 on Q. affinis and Q. laurina ( Pujade-Villar et al. 2012a; Tormos et al. 2014; Pujade-Villar 2017; Lobato-Vila et al. 2018, 2019, 2020b). It can be also obtained from sexual galls of A. quercuslaurinus (non-tuberous) and from other tuberous galls initiated by different species of Andricus (Lobato-Vila et al. 2019) . According to Lobato-Vila et al. (2020b), S. pseudofilicornis can be also reared from woolly galls induced by different Andricus and Striatoandricus species, as well as from non-woolly galls (tuberous and non-tuberous) initiated by Andricus , Atrusca , Cynips , Dros , Neuroterus and other undetermined galls on oaks of both Quercus and Lobatae sections.

Remarks. The morphological variability of S. pseudofilicornis , as well as its host preferences, was comprehensively treated and illustrated by Lobato-Vila et al. (2020b: 704).
