Remember the myrmecological disagreement over maintaining Pyramica as a separate genus from the similar Strumigenys?
After fulminating on the issue for some months, I’ve decided to throw my lot in with the synonomy. I give up. They’re all just Strumigenys. I have updated my galleries accordingly.
There has not been any new research to shed light on the problem. Rather, my change is mere opinion. Considering the sizeable morphological variation within these groups and the difficulty separating them on most characters except the mouthparts- which may be prone to ecology-based convergence- I see no reason to reject the most recent taxonomic arrangement by De Andrade & Baroni-Urbani (pdf).
Until the publication of a comprehensive species-level phylogeny, then, long live Strumigenys!
