Taxonomy and host-plant relationships of the psyllid genus Mitrapsylla (Hemiptera: Psylloidea: Psyllidae) in Brazil

摘要

The Brazilian species of Mifrapsylla, 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.
