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.

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).
