In cities located in environments of high biological importance, urbanization leads to changes in biotic diversity, while monitoring these changes can be difficult. Studies have pointed to the use of metrics that replace species as an alternative. Surrogate models are easily determined measures of biodiversity that correlate strongly with species richness and with what you want to investigate, being useful for detecting or monitoring environmental changes. The use of higher taxonomic levels has been applied to groups of megadiverse organisms, such as arthropods, since difficulties in identifying species are predictable. The aim of this study was to evaluate the practicality of using taxonomic diversity of ants as a surrogate of green area coverage in an urban environment. Four levels of "surrogate resolutions" (subfamily, genus, indicator taxa, and intermediate resolution) were assessed to the taxonomic diversity of ants across three levels of urban green areas (Small = 0 to 35%
