Extract

Geromyia gen.n. is erected to accommodate the millet grain midge, Itonida penniseti Felt, 1920, a species that attacks developing grain of bulrush millet, Pennisetum typhoides and other species of Pennisetum. Cecidomyia penniseti Felt, 1920, Itonida seminis Felt, 1921 and Cecidomyia pennisetoides Barnes, 1956 are synonymised under G. penniseti. The male, female and larva are described and illustrated in detail and the life-cycle and seasonal biology are described from field observations at Bambey, Senegal. G. penniseti is recorded from P. typhoides in India, the Sudan, Nigeria, Senegal, Niger and Upper Volta and is provisionally recognised in collections from P. polystachyon and P. pedicellatum in Ghana, Uganda, Madagascar and Nigeria.
