The idea of an area of endemism implies that different groups of plants and animals should have largely coincident distributions.This paper analyses an area of 1152 000 km2, between parallels 21º and 32ºS and meridians 70º and 53ºW to examine whether a largeand taxonomically diverse data set actually displays areas supported by different groups. The data set includes the distribution of805 species of plants (45 families), mammals (25 families), reptiles (six families), amphibians (five families), birds (18 families), andinsects (30 families), and is analysed with the optimality criterion (based on the notion of endemism) implemented in the programNDM/VNDM. Almost 50% of the areas obtained are supported by three or more major groups; areas supported by fewer majorgroups generally contain species from different genera, families, or orders.
