FIGURE 5. Geographic pattern of species richness for the Australian Iridomyrmex fauna. A. Number of species (top number) and collecting events (bottom number in parentheses) clustered by the botanical regions suggested by Barlow (1985), based on material examined during this study. B. Density plot based on A as well as the distribution of individual species, with areas containing greater than approximately 30 species labelled "H" ("high" diversity) and areas with fewer than approximately 20 species labelled "L" ("low" diversity).
