Colaspis sp.
I cannot confirm this ID.

Iustin sent me three vouchers, one male and two female. Comparing against Blake 1975's paper on this group (to which it surely belongs), the tip of the aedeagus of C. brownsvillensis appears to be drawn symmetrical. However, the male specimen in front of me has a distinct asymmetrical tip, not as strong as in C. melancholica but asymmetrical nonetheless. Also the curvature of the aedeagus is unlike either of those species. It also lacks the spine on the hind tibiae that would be present in C. melancholica and related species.

In short, I'm very puzzled by these beetles. Either there is some variation in the C. brownsvillensis species, or this is something else.

stunned.
