Bacchisa (s. str.)

I have Breuning's Astathini revision as a pdf if you want it. I am sure there are scientific ways to separate these two genera.

There are many undescribed species in both of these genera, and possibly some species described from Sumatra and West Malaysia which also occur in Borneo. It would take lots of work to study all of the holotypes. I think you must assume that Breuning's revision of this tribe was very inaccurate and incomplete, but that's all their is right now.

Ok with you. Astathini Species are easy to separate, and I can not beleive that this tribe is harder than Clytini or Acalolepta species. The problem could be to have enough material and series of each species : I use to catch specimens one by one in natura...

Hello Xavier,

This is one of the specimens I posted on the forum on behalf of Ole Mehl†. This specimen, along with his collection, was supposed to go to the Zoological Museum in Copenhagen, where it probably is as we speak.

There are 4 or 5 described Bacchisa described from Borneo (per TITAN) with this general color.... All are mostly testaceus, some are lighter and some are a little darker.

Based on 50 specimens in hand, I have about 12 species, all from Sabah. There could be more or less, as there is some variability. For instance, one species has all black heads. Another is heavily tomented. Another has a peculiarly elongated head. Others have different punctation on the head or elytra.
