Guatemala to Amazonian Brazil. Suriname is the type locality.


Eurhopalothrix bolaui is more likely to be found in second growth wet forest habitats than primary forest. It is a lowland species, occurring from sea level to 800 m elevation in Central America. One examined queen from Venezuela was found at 1350 m, in montane forest. Most specimens are from Winkler and Berlese samples of sifted litter and rotten wood from the forest floor. However, on multiple instances workers and in one case a dealate queen have been found by searching beneath loose bark of rotten wood.


This species has a single tooth row on the mandible (the similar E. gravis has a double tooth row). It has a full complement of 3 pairs of spatulate setae on the promesonotum (a set of similar, mostly montane species have reduced mesosomal pilosity). Eurhopalothrix zipacna is a larger, darker version of E. bolaui that occurs in cloud forests of Guatemala and Honduras.


A worker and queen (probable nestmates) from Osa Peninsula, Costa Rica, are considerably smaller than other Central American material. A queen from Venezuela is larger, darker, and with more roughened face sculpture compared to Central American queens.
