Longino (2006) - Myrmelachista ambigua was described from a single worker from St. Vincent. Given the relative uniformity of workers, the published description and even examination of the type will be of little use. Queen and male-associated collections of Myrmelachista from St. Vincent will be needed to compare with material from other parts of the Caribbean. Wheeler (1908) considered the worker of Myrmelachista ramulorum close to ambigua.


Worker with nine antennal segments. See Longino's comments regarding Caribbean Myrmelachista.
