A species of Hydrellia, discovered on rice at Ibadan, Nigeria, is described and named Hydrellia prosternalis sp. n. The third-instar larva and puparium are described. Eggs are laid singly per seedling on leaves, and larvae consume the growing points of the shoots, resulting in severe stunting. Pupation takes place in the centre of the shoot, just below the ligule. Hymenopterous parasites of a species of Opius (Braconidae), a genus near Peckelachertus (Eulophidae) and a genus near Cirrospilus (Eulophidae) were reared from pupae.
