Species Groups
Kohout (2008) - The subgenus Myrmothrinax has never been formally subdivided, but with the number of its constituent species rapidly increasing, I am proposing two species-groups, based on the most characteristic feature in the workers, the relative lengths of the petiolar spines. The aequalis-group includes species with the petiolar spines more-or-less subequal or with the middle spine shorter than the lateral pair. The thrinax-group includes those species with a distinctly elongated middle spine.
