This species is reasonably widespread in southeast Asia occurring from the Malay Peninsula, possibly including southern Thailand, to Indonesia where the species occurs in Borneo including Brunei and possibly Sumatra (A. Suyanto pers. comm. 2006) and the Philippines, where it is known only from one specimen from Luzon (Abra province) and three from Mindanao (Misamis Oriental province) (Kock 1969; Utzurrum 1992; L. Heaney pers. comm. 2006), although it probably occurs over a substantial part of the Philippines (L. Heaney pers. comm. 2006).
