from Kubah National Park, Sarawak, Malaysia (western Borneo).
We report on a record of Rhacophorus dulitensis from Kubah National Park in western Sarawak. The new record extends the known geographical range of the species 300 km to the west.
Rhacophorus dulitensis is endemic to Borneo, the largest of the Southeast Asian Greater Sunda Islands, where it occurs in primary lowland forest at elevations below 600 m a.s.l. (Harvey et al. 2002; Malkmus et al. 2002). Although not a rare species, it is seldom encountered because it lives in the canopy layer of forests and only descends to lower vegetation in order to breed (Dehling 2011).
Rhacophorus dulitensis has a scattered distribution in central and northern Borneo. Originally described from Mt. Dulit in eastern Sarawak (3°25’ N, 114°00’ E), it has since been recorded from several localities in central and eastern Sarawak, Brunei Darussalam, Sabah, and East Kalimantan (Boulenger 1892; Inger et al. 2004; Inger and Stuebing 2005; Das 2007; Figure 1).
