Interpretive Summary: A species of fly, a gall midge, was found to be injurious to leaves of golden currant. A study determined that it is new to science. The species is described and illustrated and classified in a new genus. Comparisons with other genera were made to determine where the genus occurs in the classification. The name is available to support further work on the biology and impact on currant.

Technical Abstract: Ribesia sarae Gagné, new genus, new species(Diptera: Cecidomyiidae), is described from simple leaf blister galls on Ribes aureum(Grossulariaceae) from Montana. The female abdomen is superficially similar to that of CystiphoraKieffer and SackenomyiaFelt. The three genera are compared. Because of strong differences found in their male terminalia it appears that any similarities in the female abdomens are the result of convergence. Sackenomyia ribesifolia(Fedotova) from Ribesin Kazakhstan is a new combinationin Ribesia.
