Range DescriptionThis species is endemic to the western part of the Barisan mountain range in Sumatra (Bengkulu, West Sumatra and North Sumatra Province) and Siberut in Mentawai Islands (Dring et al. 1990). A record from Palembang in Sumatra is regarded as questionable (Zug et al. 2011). Due to the complex trade dynamics in Sumatra the provenance of specimens east of the Barisan mountain range is in doubt.
In their analysis of the distribution of members of the P. curtus group, Zug et al. (2011) could only verify the presence of this species at Mt. Kabor and Kaba Wetan, although these authors also accept the validity of records from Sibolga (Shine et al. 1998), Padang, Bandar Lampung (Barker and Barker 1994) and Bengkulu (Keogh et al. 2001).
The species was previously thought to occur in Peninsular Malaysia, Sumatra and Borneo, but is nowadays considered to be endemic to Sumatra, where it is restricted to the west side of the Barisan mountain range.
