On the identities of Rhacophorus jarujini Matsui and Panha, 2006 and Rhacophorus orlovi Ziegler and Köhler, 2001 (Amphibia, Anura, Rhacophoridae) from Thailand

We investigated the respective identities of Rhacophorus jarujini and R. orlovi in Thailand based on specimens collected from several localities in north-eastern Thailand and specimens from museums, namely American Museum of Natural History, Field Museum of Natural History, North Carolina State Museum of Natural Science, Khon Kaen University Vertebrates Collection and Thailand Natural History Museum. Our results confirm that the specimens from Amnat Charoen and Ubon Ratchathani provinces, Thailand, which were previously identified as R. orlovi, are in fact R. jarujini. We therefore propose removing R. orlovi from the list of amphibian fauna of Thailand and that former records of R. orlovi should be replaced by R. jarujini. Furthermore, we report a new record of R. jarujini based on specimens collected from Phu Phan National Park (Sakon Nakhon province), the northernmost record of the species in Thailand.
