This is not C. ruddii, they have much more contrastingly gold/red/purple reflections, very dense punctation and are very broad.
This is one of the slender species, like C. leptomandibularis or a slim C. angustula. Without looking at the thickness of the mandibles I dont dare say which although it seems a good fit for the former.
