Odontomachus affinis

Identification
A member of the Odontomachus haematodus group.

Distribution based on Regional Taxon Lists
Neotropical Region: Brazil, Colombia.

Biology
While this species has been reported to nest in ant gardens (Campbell et al., 2022; Madison, 1979) it does not seem to be a true ant-garden taxon (i.e., one that is able to initiate ant gardens or is restricted to ant gardens) and is more likely to be a secondary resident or opportunistic ant-garden nester.
