Apalharpactes reinwardtii is known from just six forested mountains in West Java, Indonesia: Gunung Halimun, Gunung Salak, Gunung Gede-Pangrango, Gunung Patuha-Tilu, Gunung Wayang and Gunung Papandayan. There are only recent records from three of these (Halimun, Salak and Gede-Pangrango). The historical range totals 11,600 km2. Although it has been stated to occur from 800-2,600 m, little forest remains below 1,000 m away from Halimun, and the species appears to be rarer at higher elevations. The only site where the species appears to be common now is Gunung Halimun, but only at lower elevations. The population size of this species may be as low as a few hundred pairs (Collar and van Balen 2002).
