Species Account of Amphibians and Reptiles in the Eastern Slope of Mt. Bulanjao Mountain Range, Southern Palawan, the Philippines, with a New Geographic Range for the Palawan Eastern Frog Alcalus mariae (Inger, 1954)

Accounts on the amphibians and reptiles in the eastern slope of Mt. Bulanjao Mountain Range, southern Palawan, the Philippines, are presented. Currently, no published account on the herpetofauna of this mountain range exists. With this, we provide an initial overview of the amphibians and reptiles present in Palawan Island’s southernmost mountain range. A combination of visual encounter surveys along pre-established transect lines and opportunistic sampling were employed to assess the herpetofaunal diversity of the site. Voucher specimens were collected and photographs were taken for each collected species. Our sampling efforts resulted to a total of 21 species of herpetofauna recorded from the area. It is expected that more species will be documented as further surveys are conducted in other microhabitats within this mountain range. This study highlights the new geographic range and lower elevation limit for Alcalus mariae, which was previously recorded only in Mt. Mantalingahan Mountain Range extending the species’ range further south.
