Type examined. Female syntype “San Geronimo, Vera Paz, Champion.”, Cameron’s handwritten label “ Synergus dorsalis Cameron, B.C.A. , i.72.”, “ B. C. A. Hymen. I. Synergus dorsalis Cam. ”, white “ Syntype, B. M. TYPE HYM. 7.111.”, white “ Andricus guatemalensis ♀ ( Cameron, 1883) Ritchie & Shorthouse, 1987 = Andricus dorsalis ( Cameron, 1883) J.P-V det. 2009”, “ NHMUK 010814170” ( Fig. 252 View FIGURES 247–252 ).

Diagnosis. Morphologically resembles S. georgei ( Pujade-Villar, 2011) with incomplete notauli and finely striated pronotum. But in S. guatemalensis the notauli almost reach the anterior margin of mesonotum, while in S. georgei the notauli only extend across the posterior 1/2 of the length of mesoscutum. The antennae of the holotype of S. guatemalensis are lost and the mesosoma is partially covered by naphthalene crystals making the posterior margin of mesoscutum and part of the mesoscutellum hardly visible.

Galls. Densely hairy hemispherical masses attached to the midrib of the underside of the leaves. The center is hard and woody, and the fibers radiate from the center towards the edge; the larval chambers are situated along the edge, there being none in the center. Outside the woody central gall is a covering of woolly hairs, white basally, but reddish brown distally. The galls are usually found in pairs, occasionally singly.

Biology. Only an asexual generation is known, inducing galls on Quercus sp.

Distribution. Guatemala: San Jerónimo (Baja Verapaz).

Comments. Cameron (1883) described Cynips guatemalensis based exclusively on gall samples, however the drawings of the galls in the same study were morphologically discordant from his description in the text. This prob- lem has been solved recently by Pujade-Villar et al. (2022). Furthermore, Synergus dorsalis Cameron was described in the same study ( Cameron 1883); the type material of which (“ Synergus ” adult) was examined by Richie & Shorthouse (1987) who concluded that it corresponds to an Andricus . Cameron mentions that S. dorsalis was obtained from the gall of Cynips guatemalensis , therefore S. dorsalis , currently Andricus dorsalis (Cameron) , is the inducer of the gall of C. guatemalensis (currently Andricus guatemalensis ). The type female is pictured in Figs. 247 –251 View FIGURES 247–252 .
