Nice insect!
It is an Exocentrus a very rich genus of Acanthocinini.
The worldwide revision - outdated - is here in the Library.

It is Exocentrus (Pseudocentrus) guttulatus Bates, 1873.
There are several subspecies, but the taxonomic situation is unclear since they seem related to disconnected areas (impossible for the concept of subspecies!).

Ce specimen correspond à mes exemplaires de Phrae. Je les ai déterminés :
Exocentrus (Oligopsis) alboguttatus obscurior Pic, 1929

A noter que la subsp typique est décrite des Philippines, je ne connais pas la subsp de Taiwan, et enfin, je ne vois pas de différences entre obscurior Pic 1929 décrit du Vietnam et subconjonctus Gressit 1940 décrit de Hainan.
