Acromyrmex echinatior (syn. Acromyrmex octospinosus echinatior) from the tribe Attini is a eusocial insect which cuts and processes vegetation. It subsists on a specific species of fungus (genus Leucocoprinus) which it cultivates and feeds to the Queen and other colony members in the nest. This species is an excellent example of social evolution and also reproductive conflict studies as their queen mates with multiple males ensuring high genetic diversity among the nests' workers.

In 2011 the genome of a single male ant was sequenced to more than 100x depth coverage, creating a high-quality assembly of 300 Mb which is estimated to be 96% of the complete genome. 17,278 protein-coding genes were also identified. Comparisons with the sequenced genomes of ants from different subfamilies and identified a number of characteristics of the genome that may be associated with its evolution.
