description: Synergus longiscapus Pujade-Villar & Lobato-Vila, 2017
Synergus longiscapus Pujade-Villar & Lobato-Vila, 2017. Zoological Studies 56 (36): 14.
Type material: UB (holotype), paratypes in UB, USNM and AMNH [examined by the first author in Lobato-Vila & Pujade-Villar (2017)].
Material examined (37♂ & 102♀). New material collected in Mexico and deposited in UB with the following location data: MEX: 460, Santa Fe (Cuajimalpa, CDMX), 19°21’09.78’’ N, 99°15’55.02’’ W’, Ex. Loxaulus hyalinus, Q. laeta, (26.iii.2018), 23.iv-20.v.2018, JP-V leg.
Diagnosis. Synergus longiscapus is morphologically close to S. cibriani, S. citriformis and S. longimalaris (see above), whose main differences have already been commented on (see the diagnosis of S. cibriani, S. citriformis and S. longimalaris, and the identification key).
Brief redescription. Female antenna 14-segmented, male antenna 15-segmented; scape long, usually as long as or longer than F1; F1 as long as F 2 in females and just slightly longer in males; F1 of males weakly expanded apically and basally; malar space 0.6 times as long as height of compound eye; frons and vertex coriaceous to alutaceous, frons with scarce small punctures; frontal carinae absent; mesoscutum finely coriaceous; notauli incomplete and narrow, faint in the anterior 1/3; scutellum finely coriaceous, weakly imbricated posteriorly; scutellar foveae inconspicuous; circumscutellar carina well defined, but not upturned; mesopleurae anteriorly and medially with regular striae, basally smooth, speculum also 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; in males, head yellow except for a black spot in the ocellar area. For more details on the morphology of this species, see Lobato-Vila & Pujade-Villar (2017).
Distribution. Mexico. States of Ciudad de México, México, Morelos, Nuevo León, Oaxaca, Tlaxcala, Veracruz and Zacatecas (Lobato-Vila & Pujade-Villar 2017; Lobato-Vila et al. 2020b; and in this work, see the material examined).
Biology. Mainly associated with woolly galls initiated by Andricus, but also with other gall morphotypes (never tuberous galls) initiated by Andricus (like A. sphaericus and other undetermined species), Cynips, Disholcapsis, Neuroterus eugeros Pujade-Villar, 2018 and some undetermined small spherical galls on leaves, on oaks of both Quercus and Lobatae sections (Lobato-Vila & Pujade-Villar 2017; Lobato-Vila et al. 2020b). Here also obtained from Loxaulus hyalinus Pujade-Villar & Melika, 2014 (see the material examined).
