The correct pronunciation of this ant’s name is Am-blee-ah-pon-ee, with the emphasis on the antepenultimate syllable and the final “e” audible. But I don’t know anyone who says it that way.
Every English-speaking myrmecologist I know calls it “Am-blee-oh-pohn“, with the final “e” silent. That’s a shame, because the right way is also prettier. I mentioned this to May Berenbaum- whose office is across the hall from mine- and she pointed out that midwesterners inflict the same error on calzones, which New Yorkers say correctly as “cal-zon-ee.”
