About Argyrodes fissifrons O.Pickard-Cambridge, 1869
Argyrodes fissifrons O.Pickard-Cambridge, 1869 shows sexual size dimorphism: females are larger than males, reaching approximately 12 millimeters in total body length. This species has a triangular abdomen, with downward-pointing spinnerets and a backward-pointing hind end. Its body is marked with silvery spots, and it has long, thin legs. Males have distinct bumps on their head. After mating occurs, males seal the female's epigyne with a resin plug to prevent the female from mating again. Argyrodes fissifrons is a kleptoparasitic spider. It is much smaller than its common host spiders. It sometimes preys on its host Agelena limbata when the host is molting or has just finished molting. Recent research has documented this species associating with the webs of Cyrtophora spiders on Orchid Island, Taiwan. On these Cyrtophora host webs, A. fissifrons scavenges by collecting small prey items that the host spiders ignore.
