RESUMO
The Brazilian species of Mitrapsylla, a Neotropical genus of jumping plant-lice, are reviewed. Twenty-seven species are described as new, and one species originally described from Panama is recorded for the first time from Brazil. This brings the number of Brazilian species from 12 to 40 and for the Neotropical region to 51. The new species are illustrated and Mitrapsylla ceplaciensis (White Hodkinson), M. cubana Crawford and M. itaparica (Crawford) are redescribed. A key for the identification of males is provided for the Brazilian species and information is given on host-plants, habitat and distribution. Host-plants, all Leguminosae, are confirmed for 15 of the new species. The genus is predominantly tropical but extends into the subtropical states in South Brazil.

Jumping plant-lice (Hemiptera: Sternorrhyncha: Psylloidea) are a group of phloem-feeding insects with nearly 4000 described species. Previous records from Colombia comprise 19 genera of all eight known families. The revision of material deposited in six Colombian and three foreign museums yielded another nine genera that constitute new country records. Material from 16 departments was examined. Each genus is diagnosed and information is provided on biology, damage and host-plants. Local distribution maps and a generic key for the identification of adults are provided.
