Abstract: The genus Cecidomyia contains 11 species, 8 from North America and 3 from Eurasia. Most are only broadly host specific and occur on many species of pines in North America and also spruce and fir in Europe. The larvae feed on pitch and can cause extensive primary damage. The species are analyzed by use of a cladogram, and the North America species are keyed, described, and their pertinent taxonomic characters illustrated. New species described are C. brevispatula, C. fortunactus, C. reburrata, and C. tortilis
