Etymology: Named in honor to Clarence Preston Gillette (1859, Ionia County, Michigan-1941, Fort Collins, Colorado), the American entomologist who described the closest related species Synergus punctatus .
Diagnosis: Species morphologically closely related to Synergus punctatus Gillette of which is distinguished by the following combination of morphological traits: in males, head black except for a reddish-brown to chestnut colored halo around the mouth (head yellow except for a black spot in the vertex in S. punctatus ); in females, colored halo around the mouth less conspicuous and reddish-brown to chestnut (yellow and clearly defined in S. punctatus ) ( Figs. 8a, b View Fig ); F1/F2 ratio in males about 1.15 (about 1.4 times in S. punctatus ); notauli complete and visible along their entire length (inconspicuous in the anterior third of the scutum in S. punctatus ); syntergite punctuation not forming a complete band, less widespread and shorter (forming a complete band, occupying the distal half of the syntergite and reaching the ventral part of metasoma in S. punctatus ).
Female
Length: Body length 1.5-2.2 mm (n = 14).
Color: Head black, except for face surfaces surrounding the oral foveae (sometimes in a small area), which are reddish-brown to chestnut ( Fig. 8b View Fig ); frons and vertex black, occiput black; antennae testaceous; mesosoma black, tegulae yellowish; metasoma black, reddish basally; legs yellow, including coxae; forewings hyaline, light veins.
Head: in frontal view ( Fig. 2a View Fig ) quadrangular with genae convergent, 1.2 times wider than high, genae not expanded behind compound eyes. Face faintly pubescent, lower face and gena with striae irradiating from clypeus and reaching basal margin of compound eye and basal margin of antennal toruli; medial carina also present. Clypeus indistinct, ventral margin slightly projected over mandibles. Malar space around 0.5 times as long as the height of the compound eye (10:18). Anterior tentorial pits visible; pleurostomal and epistomal sulcus absent. Transfacial line about as long as the height of the compound eye. Toruli situated mid-height of the compound eye; distance between torulus and compound eye shorter than diameter of toruli; distance between toruli slightly shorter than the diameter of torulus. Frons finely coriaceous to reticulated without punctures; frontal carinae weak, but visible, not branched and not reaching lateral ocelli ( Figs. 2a, c View Fig ). Head in dorsal view ( Fig. 2c View Fig ) is about two times wider than long. Vertex finely coriaceous, without punctures. POL: OOL:LOL = 8:3.5:3; OOL as long as the diameter of lateral ocellus. Occiput ( Fig. 2b View Fig ) coriaceous, with neither rugosities nor punctures.
Antennae ( Fig. 2f View Fig ): 14-segmented (7: 4: 9: 8: 8: 8: 7: 7: 5: 5: 5: 5: 4: 7.5); filiform, not broadened apically; pubescence dense and short; placodeal sensilla little visible only on flagellar segments F7- F12. Pedicel 1.3 times longer than wide; F1 slightly longer than F2, F2 as long as F3. Last flagellar segment 3.0 times longer than wide and 1.9 times longer than F11.
Mesosoma: About 1.2 times longer than high in lateral view (including nucha), with short and not dense pubescence ( Fig. 3b View Fig ). Ratio of length of pronotum medially/laterally: 0.36. Pronotal plate absent; pronotal foveae superficial, long and separated. Lateral pronotum sculpture imbricated, with some weak carinae medially and above pronotal foveae; lateral margins of pronotum rounded, without lateral carina. Mesoescutum ( Fig. 3a View Fig ) 1.3 times wider than long, imbricated to weakly but densely transversely carinated, the interspaces coriaceous; anterior grooves weak, occupying almost 1/3 of mesoescutum length. Notauli complete, wider posteriorly and slightly convergent. Median groove almost indistinct. Parapsidial grooves almost indistinct, slightly surpassing tegulae. Scutellum ( Fig. 3a View Fig ) rounded, almost as long as wide, wrinkled, circumscutellar carina not visible; scutellar foveae superficial, shallowly impressed, smooth, more or less ovaltriangular-shaped, posterior margins almost indistinct and separated from each other by a narrow septum. Mesopleurae ( Fig. 3b View Fig ) transversely striated, speculum smooth; interspaces smooth, little pubescent basally. Metapleural sulcus well defined, reaching 4/5 parts of mesopleurae height. Propodeum ( Fig. 3c View Fig ) pubescent and weak sculptured, alutaceous with some transversal rugae; propodeal carinae straight and almost parallel, central area alutaceous and pubescent. Nucha sulcated dorsally and laterally.
Legs ( Fig. 2e View Fig ): Tarsal claws with a small basal tooth.
Wings: Forewings pubescent with marginal setae, longer than mesosoma plus metasoma. Radial cell closed, 2.5 times longer than wide; areolet indistinct but visible, small. Rs + M vein visible in almost 3/4 parts, not reaching basal vein. Basal cell pubescent.
Metasoma ( Fig. 3d View Fig ): Shorter than head plus mesosoma length, slightly 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 band of micropunctures extending a little more than 1/3 of the metasomal length; not incised dorso-distally. Hypopygial spine almost as long as wide and with a few lateral setae; apical setae not projected beyond the tip of the spine.
Male
Similar to female, except for the following morphological traits: body length 1.1-1.7 mm (n = 43). Transfacial line slightly shorter than the height of the compound eye (0.9). POL: OOL: LOL = 7: 5: 4 ( Fig. 2d View Fig ). Antennae 15-segmented (7: 5: 10.5: 9: 9: 9: 7: 6: 6: 5: 5: 5: 5: 5: 6); F1 curved, medially excavated, more expanded distally ( Fig. 2g View Fig ). Metasoma shorter than females, and almost as long as mesosoma.
Distribution: State of Zacatecas ( Mexico).
Biology: The material studied was obtained from soft galls developed on Q. laeta Liebm. and Q. rugosa Née ( Quercus section) related to the genera Atrusca and Andricus .
