This species has simplified coleopteroid morphology, it has been collected associated to ant nests of Acromyrmex lundi and feeding from the roots of Gleditsia triacanthos , as it is described in the original description of Kormilev (1955). In this same study the fifth nymph is described, it should be highlighted that beside this nymph it is only known the nymph of another vianaidid species Anommatocoris coibensis , as vianaidids have been rarely collected. Anommatocoris coleopteratus has been recorded in Uruguay by San Martin (1966). There are illustrations of the adult in Kormilev (1955) and Drake & Ruhoff, in Drake & Davis (1960) there are also illustrations of the fifth nymph.
