It is very similar to my specimens of Blepephaeus sumatrensis from Sabah except the body of your specimen is much darker, whereas my specimens are brown or reddish-brown. I think they are basically the same species.
The Blepephaeus of the Philippines can be rather variable, so perhaps it is a trait of the genus. The B. sumatrensis I have seen from Sabah are not consistently patterned. Sometimes the apical white maculae extend almost all the way to the elytral suture. The whitish pubescence on the pronotum is sometimes more prominent or reduced. I can't say for sure, but your specimen is probably B. sumatrensis. Something morphological, such as differences in the relative size of the antennal segments, or other body parts would be preferred to call this a different taxa. We really know very little about Bornean species, even many species from Sabah are impossible to understand.
Indonesia, Blepephaeus: sumatrensis?
