Abstract
Twenty-seven new species of Agromyzidae are described from Kenya and two from Uganda in the genera Melanagromyza, Ophiomyia, Tropicomyia, Agromyza, Cerodontha, Liriomyza, Phytoliriomyza, Napomyza, Phytomyza and Chromatomyia. The following new combinations are established: Cerodontha (Butomomyza) cariciphaga (Spencer 1963), Cerodontha (Butomomyza) pubicata (Spencer 1959), Napomyza eximia (Spencer 1964a) and Chromatomyia anonera (Séguy 1951); in addition Phytomyza natalensis Spencer 1964 a is raised to specific status.
New records are given of the important pest species Ophiomyia spencerella and Liriomyza trifolii.
The distribution of Kenyan species within Africa is discussed and the Palaearctic origin of new, high altitude species from Mt. Kenya is documented.
