Remarks and distribution. The taxon was first described from Sumatra, Indonesia ( Westwood 1844). Its taxonomic status, along with that of P. discolor Westwood, 1841 , was the subject of ongoing debate ( Arrow 1899; Ohaus 1900). A later comprehensive revision reclassified it as a subspecies of P. discolor , determining that P. mirabilis and P. discolor scutellaris were indistinguishable. As a result, P. mirabilis was designated as a junior synonym, extending its known range from Sumatra to the Malay Peninsula ( Kuijten 1992). In Wada’s dissertation ( Wada 2015), the species was recorded in Phang Nga Province, South Thailand, under the name P. discolor mirabilis . In addition, the priority of the taxon is the same as in P. dimidiata .
