With a little work I moved the seam into an area where it will not easily be seen.

1. Lambert shaders showing where how the model was cut up for UV layout. Note that the model was cut in half then planer projections where taken, then the two body haves and the top and bottom mandible things were flipped and sewn.

I left the inside of the legs and underbelly and the middle mandibles flipped and overlapped so they could be painted at the same time. You could separate them (the trade off is less texture space.
