careful examination of the antennae, really need comparative material. Anthrax has rather quadrate second antennal segment, Spogostylum has 2nd antennal segment flat, saucer-like, with 3rd antennal segment somewhat enclosed by it. However, as you might deduce from my wording, it is subtle and rather variable.

If I had a museum near... The most near from here is in Madrid - Spain! I will go there very soon.

And if this was a Spogostylum which would be the best probabilities? (and in the case for Anthrax as well..)
