Diagnosis. Synergus longimalaris is morphologically close to S. cibriani, S. citriformis (see above) and S. longiscapus Pujade-Villar & Lobato-Vila, 2017 (see below), whose main differences have already been commented on (see the diagnosis of S. cibriani and S. citriformis, and the identification key).

Brief redescription. Female antenna 14-segmented, male antenna 15-segmented; F1 1.5 times as long as F2; F1 of males slightly curved, faintly expanded apically and basally; 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 alutaceous to coriaceous, frons with scarce small punctures; frontal carinae absent; both mesoscutum and scutellum alutaceous to finely coriaceous or reticulated; notauli complete and visible in their whole length; scutellar foveae shallowly impressed, almost inconspicuous; circumscutellar carina well defined, with a slightly projected margin; mesopleurae basally and medially regularly striate, speculum smooth; metasoma not dorsodistally incised, pointed and with a few weak micropunctures forming a posterodorsal patch; radial cell closed, 2.4 times as long as wide; tarsal claws with a basal tooth; body black and yellow. For more details on the morphology of this species, see Lobato-Vila & Pujade-Villar (2017).

Distribution. Mexico. Originally described from the state of Jalisco (Lobato-Vila & Pujade-Villar 2017) and here also reared from galls collected in the states of Hidalgo, Mexico, Michoacán and Morelos (see the material examined).

Biology. Originally reared from a gall of Amphibolips on Quercus conzattii Trel. (Lobatae section) (Lobato-Vila & Pujade-Villar 2017). The new material presented here was reared from galls of Amphibolips dampfi Kinsey, 1937 and an undetermined species of Amphibolips on Q. affinis Scheidw. (Lobatae section); from galls of Andricus cylindratum (Kinsey, 1937) on Q. glabrescens Benth. (Quercus section); from galls of Andricus from the group tecturnarum on an unidentified species of Quercus; and from galls of an undetermined species of Amphibolips on an unidentified species of Quercus (see the material examined).
