About Allagelena opulenta (L.Koch, 1878)
Allagelena opulenta is a species of funnel weaver spider that belongs to the family Agelenidae. It was first formally described by Ludwig Carl Christian Koch in 1878. This species is native to Japan, China, Korea, and Taiwan. It resembles Allagelena bistriata in appearance, but can be told apart by several distinct features: the structure of its patella, and the shape of its retrolateral tibial apophysis. Venom from Allagelena opulenta is used to produce the insecticidal toxin agelenin.
