The furthest you can get with this is Perginae. This is one of the Myrtaceae feeding genera which includes Acanthoperga, Antiperga, Paraperga, Perga, Peragrapta, Pseudoperga and Xyloperga.
As there is are no systematic references or diagnostic characteristics of the larvae and with over 50 species within this grouping, it's almost impossible to determine the species, let alone genera in which they belong to.
Its a bit hard to see flower shape from the photo, but I think its either nigromontana or semilunulata, possibly the latter given the forward facing labellum lateral lobes and dorsal sepal. D pardina is darker with thinner lateral lobes.
