Ants of Costa Rica on the
am well on the way to putting together a manuscript on the Crematogaster of
Costa Rica. I will be dealing with 31 taxa that are known from
Costa Rica, but the paper will have implications for the wider
There will be a large amount of synonymy, because a relatively
small number of species/species complexes have very wide distributions,
and I will be taking a "synonym until proven otherwise" approach.
In addition there will be a number of new species, most of which
are known only from Costa Rica at this point. The key should
be able to help identify material of the common widespread species
anywhere in the Neotropics, with the caveat that local undescribed
species should be expected in areas that have not been thoroughly
surveyed, especially if there are mountains.
