Parastasia mirabilis Arrow, 1899: 488 [original description; synonym of P. discolor scutellaris by Kuijten (1992: 61)]). 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.
