Natural History:

This species occurs in wet forest leaf litter, and is most often obtained in sifted litter samples. A Brazilian species, Thaumatomyrmex mutilatus, is a specialist predator of polyxenid millipedes (Brandao et al. 1991), and thus ferox may be as well.

Comments:

Longino note, 10 Nov 2013: DNA barcoding show this to be a complex of species. A small, narrow-headed form occurs from Honduras southward. It contains three DNA barcode clusters, but I can't find any morphological correlates. A large, broad-headed form occurs in Honduras and is sympatric with the small form(s). All the specimens from north of the Motagua fault (Guatemala, southern Mexico) look very uniform and are intermediate in size and head shape. I don't have any DNA data for these northern specimens.
