Technomyrmex fisheri Bolton 2007
Madagascar, line drawing by Barry Bolton
Last month, British myrmecologist Barry Bolton published the first ever global synthesis of the ant genus Technomyrmex. The tome describes 37 new species, including Technomyrmex fisheri from Madagascar, named after Brian Fisher of Antweb. I’m always keen to try out new taxonomic keys, so I tested Bolton’s out on several unidentified African and Australian species in my collection. As is nearly always the case with Bolton’s meticulous work, the key worked flawlessly. I only wish I had more Technomyrmex to key.
Perhaps the most notable finding of the study, aside from the plethora of new species, is one that might upset the Pest Control folks. Bolton has discovered that the infamous White-Footed Ant, previously thought to be the single species T. albipes, is a complex of similar species, only one of which is T. albipes. In the long run, the knowledge that there are multiple pesty species in the group will better help us determine where they came from and how to control them, but of course in the short term these are the sorts of discoveries that make people hate taxonomists. Changing names makes literature retrieval more difficult, and it’s always tricky to have to remember a new name.
The Technomyrmex causing problems in Florida can no longer be referred to as Technomyrmex albipes. It is now Technomyrmex difficilis. Perhaps appropriately, we can now call this pest the “The Difficult Ant”. In any case, it looks like this in the field.
