The same species?

The abdomen with its a sharp peak and the tendency of the larger legs to be pointed forwards when the spider is at rest are characteristic of Argyrodes species, including this one. Also normal for this kind of spider is the practice of scavenging on the edge of the webs of large orb-weaving spider species.
