Anelosimus jabaquara (Theridiidae) is a social spider that lives in communal nests using tree leaves as retreats and it is known only from Brazil. There have been no studies that address sexual aspects in this species. This paper describes the sperm induction of this species under laboratory conditions. Out of a total of 20 males, we observed eight males performing sperm induction after copulation. Sperm web characteristics and description of the male behaviour during sperm induction are described. We also compared this process with that of the subsocial spider Anelosimus vierae.
