Trachymyrmex is a genus of fungus-growing ants in the subfamily Myrmicinae. The genus is mainly tropical in distribution, with most species being found in Central and South America.

The queens of the species appear to mate with only one male on their nuptial flight.{{Cite journal|last1=Murakami|first1=T.|last2=Higashi|first2=Seigo|last3=Windsor|first3=Donald|date=2000-09-01|title=Mating frequency, colony size, polyethism and sex ratio in fungus-growing ants (Attini)|journal=Behavioral Ecology and Sociobiology|language=en|volume=48|issue=4|pages=276–284|doi=10.1007/s002650000243|bibcode=2000BEcoS..48..276M |s2cid=11870497|issn=1432-0762}}

Species

A number of species were moved from Trachymyrmex based on molecular phylogeny by Solomon et al. 2019. Of the species formerly included, nine were retained in Trachymyrmex, while 31 of the species were moved to the new genus Mycetomoellerius, and an additional nine moved to Paratrachymyrmex.{{cite journal |last1=Solomon |first1=S.
