This taxon is described as a subspecies of excelsa. However, the genitalia is rather different, and it could be a distinct species.
The population in central Vietnam is most likely to be ssp.laotica based on its geographical distribution pattern. But I was unable to examine the specimens, I tentatively treat it as ssp.excelsa. Further taxonomic study is needed.
