In the last few years, myrmecologists have begun to go to the field with handheld GPS units. Along with aspirators and machetes, they have become part of the standard kit. But earlier collections (i.e., most collections) were not always so precise. The coarse grain of those earlier samples necessitates that these, the first maps of ant genera, are also relatively coarse in their grain. In order to use a maximum of data, we have chosen to break the world in 372 political entities, for each of which we have compiled data on the presence of each ant genus. We have tried to keep those political entities as small as possible; however, some regions remain sufficiently poorly known as to make further division into smaller regions impossible, for now. In the end, our maps have many gaps, holes and possibly even a sin of commission or two. We hope though that the maps will serve to help along the search for new records of genera. Finally, because we know that the diversity of genera and the diversity of species are well correlated; those regions that are poorly documented with regard to genera are also likely to be poorly documented with regard to species. We have chosen to create this website to provide a free access to everyone around the world who could consider these maps useful.
