description: Synergus gilletti Pujade-Villar & Lobato-Vila, 2017
Synergus gilletti Pujade-Villar & Lobato-Vila, 2017. Zoological Studies 56 (36): 9.
Type material: UB (holotype), paratypes in UB, USNM and AMNH [examined by the first author in Lobato-Vila & Pujade-Villar (2017)].
Diagnosis. Synergus gilletti is morphologically close to S. punctatus Gillette, 1896 (see below), but differs from this species mainly by having F1 just slightly longer than F 2 in both sexes (F1 just slightly longer than F 2 in females and 1.4 times as long as F 2 in males of S. punctatus), notauli complete (incomplete in S. punctatus) and the metasoma with an incomplete band of micropunctures occupying 1/3 of its length (with a complete band occupying the distal half in S. punctatus) (see the description of both species and the identification key).
Brief redescription. Female antenna 14-segmented, male antenna 15-segmented; F1 just slightly longer than F2; F1 of males curved and expanded distally; malar space 0.6 times as long as height of compound eye; frons and vertex finely coriaceous, without punctures or just with scarce small piliferous punctures; frontal carinae weak and narrow, not reaching lateral ocelli; mesoscutum imbricated with weak, discontinuous transversal elements; notauli complete and visible in their whole length, less impressed anteriorly and interrupted by transversal elements; scutellum wrinkled and scutellar foveae ovate to subtriangular, shallow, weakly sculptured, separated by a narrow carina; circumscutellar carina inconspicuous; mesopleurae basally and medially regularly striate, speculum smooth; metasoma not dorsodistally incised, slightly pointed and with an incomplete band of micropunctures extending posteriorly somewhat more than 1/3 of the syntergite length; radial cell closed, 2.5 times as long as wide; tarsal claws with a basal tooth; both females and males completely black, except for the surface surrounding the oral fovea, which is brownish to chestnut. For more details on the morphology of this species, see Lobato-Vila & Pujade-Villar (2017).
Distribution. Mexico. State of Zacatecas (Lobato-Vila & Pujade-Villar 2017).
Biology. Reared from woolly galls induced by an undetermined species of Andricus on leaves of Quercus laeta (Quercus section), and from galls induced by undetermined species of Atrusca on Q. laeta and Q. rugosa Née (Quercus section) (Lobato-Vila & Pujade-Villar 2017).
