Mexico, Guatemala, El Salvador (type locality), Costa Rica, Colombia.


Body covered with moderately abundant long flexuous setae, or body completely devoid of erect setae; lacking abundant appressed lanose pubescence (JTL-002 has lanose pubescence).

Natural History

I know this species primarily from Winkler samples of sifted litter from the forest floor. All collections have been from mature wet forest. It is known from sea level to 1200m elevation.


I used to consider the setose and non-setose versions of tatusia to be separate species, but CO1 data revealed the variation to be intraspecific. The polymorphism occurs in Costa Rica and Guatemala.
