Etymology: Named in honor of Dr. David Cibrián Tovar (Universidad Autónoma Chapingo, Mexico), who collected galls from Mexico for our studies.

Diagnosis: This species is morphologically related to S. citriformis (Ashmead) (= S. elegans Nieves-Aldrey and Medianero syn. nov.) and S. laticephalus Nieves-Aldrey and Medianero. The new species differs from S. laticephalus by the width of the head in dorsal view, which is much shorter (2.7 times wider than long in S. laticephalus ); also, by the presence of metasomal micropunctures (no micropunctures in S. laticephalus ) and the absence of rugae in the scutellum (with some transverse rugae in S. laticephalus ). Synergus cibriani sp. nov. mainly differs from S. citriformis by having the malar space about 0.8 times as long as the height of the compound eye (0.6 in S. citriformis ), frons and vertex with some scattered little punctures (no punctures in S. citriformis ), metasomal syntergite with a posterodorsal patch of micropunctures (no micropunctures in S. citriformis ), and F1 of males slightly expanded basally and straight apically (slightly expanded apically in S. citriformis ).

Female

Length: Body length 3.0- 3.4 mm (n = 4).

Color: Head yellowish to brown; frons and vertex medially black, chestnut laterally; occiput black; antennae yellowish to brown; mesosoma generally black, tegulae pale yellow; metasoma black dorsally, light chestnut basally; legs yellow, the base of metacoxae with a more or less extended brownish to blackish coloration; wings hyaline, veins light brown to yellow.

Head: in frontal view ( Fig. 1a View Fig ) more or less quadrangular, about 1.2 times wider than high, genae slightly expanded behind compound eye. Face faintly pubescent, lower face and genae with thin, dense and regular striae irradiating from clypeus and reaching basal margin of compound eye and basal margin of antennal toruli; medial carina inconspicuous. Clypeus indistinct, ventral margin not projected over mandibles. Malar space about 0.8 times as long as the height of the compound eye (4.2:5). Anterior tentorial pits visible; pleurostomal and epistomal sulcus absent. Transfacial line longer than the height of the compound eye (1.3). Toruli situated mid-height of the compound eye; distance between torulus and compound eye as long as the diameter of toruli; distance between toruli shorter than the diameter of toruli. Frons finely coriaceous to reticulated with some scattered little punctures; frontal carinae absent. Head in dorsal view ( Fig. 1c View Fig ) is about two times wider than long. Vertex finely coriaceous with some scattered and little piliferous punctures between the ocelli. POL: OOL:LOL = 2.4:1.6:1.2; OOL about 1.5 times longer than the diameter of lateral ocellus. Occiput coriaceous, with some scattered piliferous punctures.

Antennae ( Fig. 1f View Fig ): 14-segmented (2.7: 1.3: 3.4: 2.6: 2.4: 2.2: 1.9: 1.6: 1.3: 1.2: 1.1: 0.9: 0.9: 1.7); filiform not broadened apically; pubescence dense and short; placodeal sensilla little visible on flagellar segments F3-F12. Pedicel about 2.2 times longer than wide; F1 1.3 times longer than F2, F2 slightly longer than F3. Last flagellar segment 2.8 times longer than wide and 1.9 times longer than F11.

Mesosoma: Slightly longer than high in lateral view (including nucha), with short and not dense pubescence ( Fig. 1e View Fig ). Ratio of length of pronotum medially/laterally: 0.26. Pronotal plate absent. Lateral pronotum sculpture coriaceous to imbricated; lateral margins of pronotum rounded, without lateral carina. Mesoscutum ( Fig. 1b View Fig ) about as long as wide, strongly coriaceous to imbricated; anterior grooves weak, occupying about 1/4 of mesoescutum length. Notauli complete but faint in the anterior 1/3, wider and convergent posteriorly. Median groove weakly impressed, almost inconspicuous. Parapsidial grooves visible, reaching the anterior margin of tegulae. Scutellum ( Fig. 1b View Fig ) rounded, as long as wide, coriaceous anteriorly, imbricate posteriorly; circumscutellar carina visible but not projected; scutellar foveae inconspicuous. Mesopleurae ( Fig. 1e View Fig ) with a few transversal striae located medially and anteriorly, smooth dorsally and basally, speculum also smooth; interspaces alutaceous, little pubescent basally. Metapleural sulcus well defined, reaching about 3/4 parts of mesopleurae height. Propodeum ( Fig. 1h View Fig ) pubescent and with a weak sculpture; propodeal carinae slightly curved and convergent basally, central area with a weak sculpture and pubescent. Nucha sulcated dorsally and laterally.

Legs ( Fig. 1i View Fig ): Tarsal claws with a small basal tooth.

Wings: Forewings pubescent with short marginal setae, about as long as mesosoma plus metasoma. Radial cell closed, 2.4 times longer than wide; areolet absent. Rs + M inconspicuous, not reaching basal vein. Basal cell faintly pubescent.

Metasoma: About as long as head plus mesosoma, longer than high in lateral view. First metasomal segment sulcated dorsally and laterally. Syntergite smooth, anterolateral pubescence composed of a group of 4-5 setae, with a few weak micropunctures forming a posterodorsal patch; not incised dorso-distally ( Figs. 1j, k View Fig ). Following segments and hypopygium clearly punctured. Hypopygial spine about as long as wide and with a few lateral setae; without apical setae.

Male

Similar to female, except for the morphological traits that follow: body length 2.9-3.1 mm (n = 4). POL: OOL:LOL = 2.5: 1.6: 1.4 ( Fig. 1d View Fig ). Antennae 15-segmented (2.4: 1.3: 3.7: 2.7: 2.5: 2.2: 2.0: 1.8: 1.6: 1.4: 1.3: 1.2: 1.1: 1.0: 1.4); F1 slightly curved, medial excavation weak, slightly expanded basally, almost straight apically ( Fig. 1g View Fig ). Syntergite punctuation slightly extended laterally but not forming a complete band ( Fig. 1l View Fig ).

Distribution: State of Michoacán ( Mexico).

Biology: The studied material was obtained from soft galls developed on some undetermined species of Quercus and from Q. glabrescens Benth. ( Quercus section), related to the genera Disholcaspis and to one undetermined gall, respectively.
