Synergus cibriani Pujade-Villar & Lobato-Vila, 2017 Synergus cibriani Pujade-Villar & Lobato-Vila, 2017. Zoological Studies 56 (36): 3. Type material: UB [examined by the first author in Lobato-Vila & Pujade-Villar (2017)]. Diagnosis. Synergus cibriani is morphologically close to S. longimalaris Pujade-Villar & Lobato-Vila, 2017 (see below), from which differs mainly by having POL 1.5 times as long as OOL (equal in S. longimalaris), F1 1.3 times as long as F2 (1.5 in S. longimalaris) and notauli incomplete (complete in S. longimalaris), among others (see the identification key); also, to S. citriformis (Ashmead, 1885) and S. longiscapus Pujade-Villar & Lobato-Vila, 2017 (see below), but differs from them by having the malar space 0.8 times as long as height of compound eyes (0.6 in these two species) (see the diagnosis and descriptions of all these related species and the identification key). Brief redescription. Female antenna 14-segmented, male antenna 15-segmented; F1 1.3 times as long as F2; F1 of males slightly curved and expanded basally, almost straight apically; face wide, trapezoid to subquadrate, transfacial line about 1.3 times as long as height of compound eyes; malar space 0.8 times as long as height of compound eye; frons and vertex finely coriaceous, with scattered small piliferous punctures; frontal carinae absent; both mesoscutum and scutellum strongly coriaceous to imbricated; notauli narrow and incomplete, faint in the anterior 1/3; scutellar foveae inconspicuous or absent; circumscutellar carina well defined but not projected; mesopleurae medially with a few transversal striae, basally and dorsally smooth; metasoma not dorsodistally incised, pointed and with a small posterodorsal patch of micropunctures; following segments and hypopygium, punctate; radial cell closed, 2.4 times as long as wide; tarsal claws with a small basal tooth; body black and yellow. For more details on the morphology of this species, see Lobato-Vila & Pujade-Villar (2017). Distribution. Mexico. State of Michoacán (Lobato-Vila & Pujade-Villar 2017). Biology. Reared from spherical galls probably of Disholcaspis on twigs of different undetermined species of Quercus, and from undetermined spherical galls on the underside of leaves of Quercus glabrescens Benth. (Quercus section) (Lobato-Vila & Pujade-Villar 2017).
