Francisco et al,
That might be fine but in the world of myrmecologists (wrongly I think) the
species-group pops up as a "modern" version of the subgenus.
What is wrong with the simple term species which I have always thought,
since VIth Form school in 1957, to be the genus name plus the species name?
Too much jargon and not enough simple English.
