Perhaps Jeanvoinea borneensis. Here are 3 specimens, which show variability in pubescence. All are about 30-33 mm.

Gerard.. you are welcome. You're specimen and mine seem to agree very well, correct?
Holzschuh identified a male of this species for me about 10 years ago. I have not seen the holotype (female) or a photo of it. This species (J. borneensis Breuning, 1961) has not been recorded outside of Borneo.
This is a nice, rare species, (4 or 5 males, and 1 female in 18 years). It took a long time for me to identify the female, since it is somewhat broader and stouter than the male. (Holzschuh only saw the male I had at that time)
There is also J. annulipes Pic, 1934 from Tonkin ( Vietnam), which I don't know. |

It differs from Acalolepta in the tuberculate prosternum.
