I disagree. It's to small to be a Fiddleback and the leg spread to body size doesn't seem consistent with a recluse to me. However, this one was in a tight corner opening between the wall and the door trim with its legs sticking out when it wasn't eating or attacking, which is a consistent "pose" with other Fiddlebacks I've seen.
And yes, Fiddlebacks are very prevalent around here and I see them quite often, but only adults. I suppose this might be a young Fiddleback but I still have doubts that it's a recluse.

looks correct. The six eyes are clearly visible, but it may be a juvenile like you mentioned.
