Abstract

A new species of the spider family Theridiidae is described from Japan under the name of Argyrodes nipponicus. It is closely related to Argyrodes fur and A. trigonum, but differs from these species in the shape of cephalothorax and the structure of sexual organs. The spiders of the species invade the webs of Agelena limbata and A. opulenta and rarely build their own web.
