Interpretive Summary: A new species of fly (Diptera: Cecidomyiidae) was recently found damaging grape berries in a vineyard in Texas. The species responsible for the damage is named, described and illustrated, and compared to another species also found on grape in Japan. The new species can now be readily identified by other scientists for future studies of its impact on vineyards in SW North America.

Technical Abstract: A new species, Asphondylia uvarum Gagné, is reported that feeds on grape berries in southwestern USA and northern Mexico. It is described and illustrated and compared in detail to the Japanese Asphondylia baca Monzen that is also known from grape as well as other Vitaceae and Caprifoliaceae. DNA sequences of barcoding region COI of the two species were compared and analyzed with 12 other species for pairwise differences. A general description of the genus Asphondylia is presented to help with further Asphondylia descriptions. Asphondylia mimosae Felt iand Asphondylia prosopidis Felt are removed from Asphondylia and placed as new combinations in Hemiasphondylia. Hemiasphondylia mimosae Möhn is a junior homonym and takes the available replacement name, Hemiasphondylia mimosicola Gagné.
