Herein, we assembled the information about genome size in ants, compiling the DNA content estimated so far, in order to evaluate the methods, the tissues and the internal standard applied to estimate the genomes size. All values were placed in a phylogenetic tree to put it in an evolutionary context and the means of the subfamilies were further compared statistically to investigate changes and trends in the variation across <em>taxa</em>. The compiled data resulted in 86 specimens of ants, comprising 69 different species. This number represents 0.52% of the total number of 13,369 ant species described, covering only 40 from 333 valid extant genera. The average Formicidae genome size was 0.36 pg (± 0.13). Most of the estimates were obtained through flow cytometry (83.5%), commonly using brain tissues, with <em>Drosophila</em> <em>melanogaster</em> as internal standard (76%). Differences in DNA content of ant species may be related to differences in the amount of heterochromatin and is not related with chromosome number. The evaluation of the genome size estimations currently available for ants has highlighted their scarcity. Such information would be valuable as independent data for the study of ant diversity and evolutionary biology. Further, we conclude that the standardization of the techniques used and a large–scale study on ant genome size are urgently required, given the importance of this insect group and the needs for the improvement in our knowledge on ant genome.</p>}, number={4}, journal={Caryologia}, author={Moura, Mariana Neves and Cardoso, Danon Clemes and Baldez, Brenda Carla Lima and Cristiano, Maykon Passos}, year={2019}, month={Dec.}, pages={29–39} }
