Octostruma batesi is very similar to the widespread O. betschi of the Amazonian lowlands, the latter differing in the presence of appressed spatulate setae on the scape and a somewhat more concave face. Octostruma batesi, O. betschi, and O. stenognatha are all similar in size and head shape and possibly form a clade. Although geographic coverage is poor, the known specimens form an allopatric or parapatric replacement series in South America. However, the provenance of the holotype of O. batesi is uncertain. The type locality, in the original publication and on the specimen, is simply "Amazonas."
Found most commonly in these habitats: 2 times found in second-growth rainforest, 1 times found in steep and rocky 2° forest with few 1° trees, 1 times found in Bamboo forest.
Found most commonly in these microhabitats: 2 times sifted litter (leaf mold, rotten wood), 1 times leaf litter, 1 times ex sifted leaf litter.
Collected most commonly using these methods: 3 times Winkler, 1 times berlese.
Elevations: collected from 289 - 1000 meters, 600 meters average
