Comment

Removed from the synonymy of Philautus petersi by Wostl, Riyanto, Hamidy, Kurniawan, Smith, and Harvey, 2017, Herpetol. Monogr., 31: 98, where it had been placed by Smith, 1930, Bull. Raffles Mus., 3: 116; Bourret, 1942, Batr. Indochine: 455; and Dring, 1987, Amphibia-Reptilia, 8: 41. See map, description of geographic range and habitat, and conservation status of nominal Philautus similis in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 533. See account by Wostl, Riyanto, Hamidy, Kurniawan, Smith, and Harvey, 2017, Herpetol. Monogr., 31: 112–116, who described the advertisement call. The following literature references Philautus petersi, but because that species is now restricted to Great Natuna Island, these accounts likely refer to Philautus larutensis: See brief account (as Philautus petersi) by Malkmus and Riede, 1996, Sauria, Berlin, 18: 27–37. See identification table (as Philautus petersi) by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 122–123, to compare this species to other rhacophorids of the Sunda Shelf region. Malkmus, Manthey, Vogel, Hoffmann, and Kosuch, 2002, Amph. Rept. Mount Kinabalu: 189, provided an account (as Philautus petersi). Chan-ard, 2003, Photograph. Guide Amph. Thailand: 150–151 (as Philautus petersi), provided a very brief account, map for Thailand, and photograph. Chan-ard, Cota, and Makchai, 2011, Amph. E. Region Thailand: 139, detailed the range in Thailand (as Philautus petersi). See brief account (as Philautus petersi) by Grismer, 2012, Field Guide Amph. Rept. Seribuat Arch.: 60–62, for the Seribuat Archipelago, West Malaysia. Sumarli, Grismer, Anuar, Muin, and Quah, 2015, Check List, 11(4, Art. 1679): 14 reported specimens (as Philautus petersi) from Lata Tembaka and Lata Belatan, Terregganu, West Malaysia, and briefly reported on their morphology and habitat. Niyomwan, Srisom, and Pawangkhanant, 2019, Field Guide Amph. Thailand: 414–415, provided a brief account (description, photographs, habitat, and range) for Thailand (in Thai).
