I will be able to post a picture in a couple hours once I'm home (or can email to anybody interested), but I have what is being called a red rump tarantula. Are there red rumps that are just brown all over? It has a different body structure from rosehairs, and does not seem as bulbous at the joints like a goliath... but I thought the red rumps were at least dark black? This thing isn't even remotely dark brown, and it does have more prominent, ever so slightly more orangey-brown hairs on it's abdomen. Unless they are sexually dimorphic or change colors from juveniles to adults, it looks nothing like any picture I've seen of a red rump.

All help appreciated!
