Male has bumps on their head. After mating, male seals the epigyne of the female with a resin plug to inhibit further copulation.

Ecology

Recently, scientists found that their association with Cyrtophora spider webs, from Orchid Island, of Taiwan. Scientists finally found that A. fissifrons scavenge on webs of Cyrtophora hosts by collecting small preys ignored by the hosts.
