Caryomyia ovalis
Gagne Description 2
Rare, on Eucarya hickories; on lower leaf surface, between veins; 2.7-3.5 mm in height, ovoid to elongate ovoid, usually longer than wide, slightly bilaterally compressed; smooth, shining, hairless, not sticky, green, turning brown; base of gall abruptly tapered to conical pedicel, leaf with short, thick exfoliation at base of gall forming short, tubular socket, with corresponding convexity on opposite leaf surface; walls hard, enclosing two chambers, the basal larval chamber about 1/3 length of gall, ovoid, smooth, longitudinally ridged, the apical false chamber elongate, thicker walled, gradually narrowed to apex. This gall is two-chambered as is that of C. caminata, but the walls of the present galls are thick and shiny, unlike those of C. caminata that are brittle, foliaceous, and matte.
