Spiny leaf beetle

I can confirm Dicladispa sp.
The genera of Asian Hispini are often not easy to distinguish. There are several genera with the same "spiny" appearance. This one is a Dicladispa, based on the facts that there are 11 antennal segments, no spines on the antennae and no spines near the fore margin of the pronotum.
A key to these genera was given by S.Maulik, almost 100 years ago:http://www.archive.org/stream/coleopterachryso02jacoiala#page/150/mode/2up
The characters in this key are still valid, but two of the genus names have changed: "Hispa" is now Dicladispa, and "Hispella" is now Hispa.

Mark, Martin, thank you so much for the informations

This is certainly a great leaf beetle, AFriyanaWiradikarta .
The grubs are leaf miners, eating between the surfaces of leaves, for safety.
