maybe, but also maybe not.
Take a good look of what you can see of the ventral wing surface (the underside) from the lower photo and compare with the E. olivacealis underside - there is no pale orange at all in olivacealis, which also has characteristic heavy black fascia that are not present on lsp380's moth. I suspect this is one of two unidentified (and possibly undescribed) Endotricha species that occur in Hong Kong.
Endotricha is a difficult genus, and many of the species are only identifiable with certainty by dis-section, so unless the moth was retained, we will probably never know which species this is. E. olivacealis does occur in HK and several specimens have been dis-sected to confirm this, but there is still a need to obtain a small series of the unidentified species, one of which has been dis-sected and doesn't appear to match anything in the literature.
