John, these are Tenebrionidae, but I think they are two different species. Can you separate them?

There is a chance that this is T. aeneus, rather than T. ruficornis. But since T. aeneus was at one time considered simply a 'variety' of T. ruficornis, and since ruficornis is the older name, I will call it ruficornis. An image of the holotype of 'Daedrosis rufipes', a synonym of Tetragonomenes ruficornis, appears in the entry for ruficornis in ALA, and it looks very like this sighting.
