Before 2018,
Trichodamon contained two species,
T. princeps and
T. froesi, described by
Mello-Leitão in 1935 and 1940 respectively, with a third species
T. pusillus previously synonymized to
T. princeps. However, a paper published in 2018 concluded that the
characters that were previously used to distinguish the two species were unreliable, and that
Trichodamon is in fact
monotypic. == Distribution and habitat ==
