I was wondering if any of you knew of any articles over Aphaenogaster, perhaps on a more worldwide scale. The genus is cosmopolitan and has about 200 species globally.
The genus has been shown to be polyphyletic in the southwest, leading to the creation of the Veromessor and Novomessor genera, as well as the creation of several new species in the northeast. I read this literature.
What I'm having trouble finding, however, is some information over species outside of North America—those in Madagascar or Australia, for example. The species in this area have some definite morphological differences compared to the North American varieties, and as such I'd like to find some information over whether or not they have ever been analyzed for the purpose of possible revision of Aphaenogaster.
Any ideas where I can find some of these?
Thanks in advance.
