Fruit fly genera south of the United States. U.S. Department of Agriculture, Technical Bulletin 1600,79 pp. The 88 genera of fruit flies in Mexico, Central America, the West Indies, and South America are discussed. Keys to all genera are pre- sented, and a synonymy, diagnosis, and discussion of each genus follow. Included for each genus is information about its distribution, its rela- tionship to other genera, its composition in terms of the species belong- ing to it, aids to its recognition, and references for identifying its species. Several diagnostic characteristics and the wing of at least one species in almost every genus have been illustrated. Four genera, previously re- garded as valid, have been synonymized with others, and three addi- tional genera, long recorded from the region, are shown not to occur in the New World or to belong to other fly families. Fruit flies comprise the most economically important family of plant-inhabiting Diptera, consid- ering the potential for agricultural damage by species of such genera as Anastrepha, Ceratitis, Dacus, and Rhagoletis. Used in conjunction with my catalog of Tephritidae published in 1967, this bulletin provides a means of identifying about two-thirds of the more than 600 species of fruit flies known to occur south of Texas and Florida.
