Yes, it's apparently Bacchisa.
Robert, and other colleagues..... Breuning did very little to help with this tribe when he revised Astathini about 60 years ago. Does anyone believe that he studied all the types of Pascoe and other workers outside of the Paris Museum? I doubt it. It is also unlikely that he tried to borrow material besides the types to look for variation in species. Still, Breuning prepared keys for all the genera and species. Amazing!
Pascoe described some species of Astathini that may be synonyms. So there started part of the problem.
I have accumulated about 15 species of Bacchisa from Sabah. They are chrysomelid mimics. No particular species is abundant. I have maybe 1 or 2 specimens of most species. So, they are usually collected in small numbers. My species vary mostly by the punctation on the pronotum and elytra, along with other subtle differences. Almost all species are 8-12 mm and yellow or testaceus, except for B. violacea, and the large B. borneotica. There is currently nobody very interested in working on this tribe, although a couple of new species have been described in recent years.
I would loan my specimens to somebody who wants to revise them.
