My first thought was Cr. saxatilis, or Cr. anthurus, looking at it thought it definitely has some strong alta traits.The red suborbital triangle, and the humeral blotch centered on the lateral line definitely point in that direction.
Not sure if Cr. cardiostigma is considered a seperate species or perhaps a subspecies/variant of alta. Haven't really seen to many pictures of them, and they are discovering new species so frequently, there is no telling what they have reclassified things as anymore. Have to agree with Ray on the whole book aspect.
Either way she is one heck of a beautiful little lady! Do you have more?
