that one in the link is probably a worn specimen, as reply post #3 in that thread stated.
Pelagodes and Thalassodes can be difficult to distinguish on that regard b/c sometimes you get a specimen with the wing fringe so worn, it's impossible to see whether there are black dots.
As for the Chinese name, different geographical regions quite often refer to the same species under different common names. My guess is the former 渺樟翠尺蛾 is used more widely in Mainland and the latter is more commonly accepted in Taiwan, but I could be wrong (it could easily be the other way round).
A quick search on google tells me some other emerald moths of this genus may also be described under these Chinese names.
For clarity I often find it easier to just refer to the moth by the binomial nomenclature in Latin.
