Abstract

A new species of gall midge, Lopesia eichhorniae sp. nov. (Cecidomyiidae, Diptera), associated with rhizomes of Eichhornia azurea (Sw.) Kunth (Pontederiaceae) is described. This is the first record of Lopesia galls in this species of macrophyte, quite common in natural and artificial lakes in Southeast Brazil. Illustrations of the adults (male and female), pupa, larva, and gall of the new species are presented.
