Resumo: | The Parsimony Analysis of Endemicity (PAE) consists in an important tool of the historical biogeography which has the purpose of detecting distribution patterns of organisms and the relationships among areas of endemism. Insect distribution data included in Membracidae-Hoplophorionini occurring in the American Continent were used in the present research in order to establish the relationships among eight predetermined areas of endemism which are: 1) Mexico, 2) Greater Antilles, 3) Central America, 4) North Andes, 5) Central Andes, 6) South Andes, 7) Amazon, e 8) South East Brazil. The data matrix was based on the presence (coded as 1) and abscence (0) of taxa in the areas. The analysis was performed with the use of computer program Hennig86 (Farris 1988) applying the comands ie (implicit enumeration), and xs w (successive weighting). Resulted in the cladogram (A2,((A6,(A1 ,(A3,(A4,A5)))),(A7,A8))) with 236 steps, consistency index = 0.94 and retention index = 0.86. Areas 7 and 8 follow a subtropical and tropical vegetation pattern made up respectively by pluvial forests and groves. The remaining areas (except 2) agree with mountainous vegetation of the Andes pattern and groves throughout the extention.
