Agastoroxenia Nieves-Aldrey & Medianero, 2010

Diagnosis. This recently described genus is readily distinguished from other genera of Synergini by the presence of 13-segmented antenna in both females and males. Additional diagnostic antennal characteristics are the pedicel being relatively long, 2.5 times as long as wide and longer than the scape and F2, and the F1 of the male antenna is strongly curved dorsally, excavated medially and expanded apically and basally. Other distinctive morphological features are the small basal tooth of the metatarsal claw, measuring less than 1/3 as long as the apical tooth and the irradiating facial striae, which are strong, broad and blunt.

Monotypic. A single species known, Agastoroxenia panamensis Nieves-Aldrey & Medianero, 2010 , described as an inquiline in unidentified Andricus galls on Quercus lancifolia SchIedl. & Cham. In Chiriquí, Piedra Candela ( Panama) (Nieves-Aldrey & Medianero 2010)
