Identification
Identification relies primarily on and association rather than features. The galls are small, spherical to slightly irregular, and dark-colored, occurring on oak leaves. Distinguishing from other Amphibolips requires examination of gall structure, location on leaf (upper vs. lower surface), and specific host oak species. Adult wasps require identification using microscopic features of , , and body .

Etymology
The specific epithet 'quercusfuliginosa' combines 'quercus' (oak, the ) with 'fuliginosa' (sooty, referring to the dark coloration of the ).
Gall characteristics
The is integral to identification. Galls are typically single-chambered, located on oak leaf blades, and mature to a dark color. Detailed gall descriptions in primary taxonomic literature should be consulted for precise identification.
