Francisco Rodríguez found this specimen also in Sierra Nevada (12-9-13). I think this is another Pseudospinolia, but tegulae looks blue. I wonder if it could be Pseudospinolia humboldti
Congratulations!!! For the finding and for the identification. Even if we cannot see the shape of the head in frontal view, I think that you're right and this one should be Pseudospinolia humboldti!
