Hosts: Carya ovata, glabra, tomentosa, cordiformis, texana

Gall (Figs. 96-97): Occasional on Eucarya hickories and found once on bitternut of Apocarya section, occurs singly or in small groups; attached to side of vein on lower leaf surface; 6.0-8.0 mm in length, recumbent, base lobed across attachment to vein but not bulbous, gradually narrowing along length to pointed apex; green, yellow, to tan, hairless; base of gall with central conical pedicel in shallow, circular indentation; wall firm, brittle, uniformly thin, larval chamber glabrous with longitudinal ridges following gall axis from leaf vein connection to apex. See remarks about similar galls under C. spinulosa.

Affinities. — See under C. eumaris. [C eumaris: Galls of several other species, C. procumbens, C. recurvata, C. spinulosa, and C. supina, have similar attachments to leaf veins, grow horizontally, are thin-walled but brittle, and have longitudinally ridged larval chambers. Larvae of all are generally similar with narrow but two- toothed spatulas and only four dorsal papillae on each abdominal segment. The adult stage has been reared for only two species of this group, the female for C. eumaris and the male for C. recurvata.]
