| It might be Daxata ustulata Pascoe, 1866, but I'm not sure. |

Attached is the illustration by Pascoe of Daxata ustulata

Other than the color difference which could be due to the freshness of the pubescence, there are few points of structural difference. According to the description and the illustration:
1) at the base of elytra, there are a few shining granules and two elevated lines, the innermost simulating a crest; (the elevated lines are lacking in my specimen)
2) behind the shoulder the elytron is slightly bowed and marked with a dark-brown longitudinal patch; this bowed feature is less distinct in my specimen.
There is another Daxata (Taxada) sumatrensis Breuning,1961, and a Daxata confusa Pascoe,1869. I have Pascoe's description of D. confusa. It doesn't seem to be the one either. |

Pascoe's illustrations are not reliable.
Breuning's keys are not reliable.

Dan, if I go by your picture's name, the specimen you posted is Daxata ustulata, type, from BMNH.
It is clearer to have the name associated.  |
