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.

32nd report of the state entomologist on injurious and other insects of the state of New York 1916: Appendix: a study of gall midges V
Felt, E. P.
(1917)
Neolasioptera vitinea Felt
The midge was reared June 15, 1907 from a conical petiole gall on grape, collected on Staten Island, N. Y. The gall is quite common in the vicinity of New York City, also at West Nyack, N. Y. It was found on Isabella grape by Mrs M. Archer Shee, Highland Falls, N. Y., and taken on grape at Albany, N. Y. The species was reared by the late Dr M. T. Thompson, Worcester, Mass., and presumably at Washington, D. C, as specimens dated April 28, 1888 are in the collections of the National Museum. Trichasis virginiensis Ashm. was reared from this gall.
Gall (pl. 3, fig. 2). This is an obpyriform or slightly curved conical petiole gall on grape. The enlargement is about 1.5 cm long and .5 cm in diameter. Each gall contains 2-4 larvae in along central chamber.
