Also can you please send a side shot of the ooth. Also where in California did you collect the ooth?
You really have two main possibilities: Stagmomantis Limbata, or Stagmomantis Californica
Based on the darker color and the non raised "zipper" covering (typically in the Californica) my ? is on it being Limbata.
Let me see if I have a few pics to show...
Stand by...
