:huh, that's not a trivial one. WSC says there is Goeldia obscura, which was described by Keyserling in 1878 as T. obscura. Then, there's T. quadriguttata, which was first described as Aranea obscura by Walckenaer in 1802. The latter was called T. obscura from 1932 to 1993 by various authors. But as the former has not been called T. obscura since 1878, i would say it's taxonomically clear that they are different species. It turns out that i messed this up when i did G. obscura ) i found "Titanoeca obscura" in Bellmann (1997), checked the WSC and took the first one i found, but didn't notice it's from South America... oh, i just checked the Talk page for G. obscura, and find an entry by myself stating exactly that. so, many thanks for pointing this out! btw, i changed some minor stuff on your page, check them out. most of the stuff is just how i like it better ;), but be sure to include parentheses around original authors if the taxon changed since then, to put genera/species in italics, and, much more important, to include a reference. you did a great job on this page, we're one step closer at getting all the 40,000 described species ) (then we can finally do mites ;) welcome to the Spiders WikiProject, glad to have you around! if you have any questions or suggestions, leave me a note, 
 cheers
