Rybaxis sp.
Rybaxis has a transverse angular sulcus near the posterior margin of the pronotum. Reichenbachia lacks a sulcus, but has three pits/foveae, the middle one small and nude and the lateral ones larger and setose.

Thanks
This looks like the right genus, and we might find out which species later, because I'm saving it for Don Chandler.

...there may be a mix on the Reichenb. page :-[

The images placed in Reichenbachia
look OK. The first one (a Tim Moyer photo) looks suggestive of Ryb*axis, but the critical characters can't really be seen and it is linked to two others where the characters are definite.
