Distribution
Western North America; specimens documented from California and associated with the University of California, Riverside entomological collections. The name honors David T. Fullaway, a Hawaiian entomologist, suggesting possible Hawaiian connections though primary type locality requires verification.

Ecological Role
As a of gall-forming psyllids, T. fullawayi contributes to natural of its . Its presence in hackberry galls represents one component of a complex parasitoid that includes Encyrtidae and other Torymidae.

Nomenclatural note
The specific epithet 'fullawayi' honors David T. Fullaway (1872-1961), entomologist with the Hawaiian Sugar Planters' Association and later the University of Hawaii, who made substantial contributions to and entomological collections in the Pacific region.
Collection history
Specimens of T. fullawayi are present in the University of California, Riverside Encyrtidae and slide collections, though the itself belongs to Torymidae rather than Encyrtidae. This reflects the broad taxonomic scope of the UCR collection, which includes many Chalcidoidea beyond Encyrtidae.
