Acontheus is a genus of trilobites belonging to the Family Corynexochidae, Order Corynexochida, and is geographically widespread having been recorded from middle Cambrian strata in Sweden, Newfoundland, Germany, Siberia, Antarctica, Queensland, China and Wales.
Acontheus appears confined to the Drumian and Guzhangian Stages, uppermost two of three Stages subdividing the middle Cambrian Miaolingian Series and, if species assignments are correct, the genus ranges in terms of the Scandinavian sequence from at least the Hypagnostus parvifrons Biozone in Wales to the Lejopyge laevigata Biozone at various locations elsewhere.
