I shot this spider on the small island of Hajo-Do, at the far south-western edge of South Korea, in June or July 2011. From comparing it to images from google, it resembles a Wolf Spider, to my untrained eye, but I have also read reports that the Funnel Web Spider has somehow found its way here, and this spider had a funnel shaped web. (If it was the latter, I was courting disaster, as my hands were only a few cm away as I adjusted my lens…) So, I’ve supplied 2 photos – One from a little further back, showing the web, and a second, much closer, getting down to macro detail.
I’m a very keen macro shooter, and am especially crazy about bugs, although my knowledge of genus etc is very limited. Feel free to explore my blog posts on my macro work on insects, and any help with identifying them would be very much appreciated.

Dear richarquis de sade,
We do not recognize your spider, and we do not have the time to research at this moment, so we are posting your excellent photos in the hope that one of our readers can provide a comment as to its identity.

Funnel Weaver Spider from South Korea

Hi Daniel and richarquis de sade:
I believe your spider is a Funnel Weaver (Agelenidae), probably in the genus Allagelena. At least three species are native to Korea: A. opulenta, A. donggukensis and A. difficilis. All three species are highly variable in appearance but I did find several images posted by Daniel Ruyle of A. opulenta spiders from Japan that look very similar to richarquis de sade’s spider. Allagelena opulenta is native to China, Korea, Taiwan and Japan.  I tried to find out if it was considered dangerous to humans but my search was inconclusive. One site did indicate that its toxin is “insect-selective”, suggesting that it is probably not dangerous. However, I would probably not be inclined to test this if I was ever confronted with the opportunity. Agelenid spiders are sometimes referred to as Funnel Web spiders but they should not be confused with the very dangerous Australian Funnel Web spiders, most infamously the Sydney Funnel Web, which belong to a different spider family altogether, the Hexathelidae. Regards.  Karl
