The gall's range is computed from the range of all hosts that the gall occurs on. In some cases we have evidence that the gall does not occur across the full range of the hosts and we will remove these places from the range. For undescribed species we will show the expected range based on hosts plus where the galls have been observed.
Our ID Notes may contain important tips necessary for distinguishing this gall
from similar galls and/or important information about the taxonomic status of
this gall inducer.

Neuroterus tantulus, new species
Small saucer-shaped galls occurring in large numbers attached by a broad base on under side of leaf in early summer. Individual galls measure 0.9-1.6 mm in diameter by 0.6-7 mm high, with an elevation in center of the concave free surface, brown, almost bare, dropping off when mature and leaving a scar 0.7 mm in diameter on the gall and a brown spot on the leaf.
Habitat.—Type locality. College Park, Md. On May 24, 1948, W. H. Anderson swept up a tablespoonful of the galls, which had fallen on a table under a heavily infested white oak tree. These were placed in a breeding cage on the ground outdoors and when examined on April 1, 1949, scores of adults had emerged and many had already died.
