E-mail : ychuaynkern@yahoo.com Stuart et al. (2006b) described thirteen specimens from Phu Luang Wildlife Sanctuary (Loei Province, Thailand) accompanied with three specimens from Phu Kradueng National Park (Loei Province, Thailand) which were originally reported as Rana livida (Blyth, 1856) by Taylor (1962) as a new species named Odorrana aureola. Molecular information supported the view that this new species was different from the related species Rana livida (from syntypes and specimens from Kaeng Krachan National Park, Phetchaburi Province, Thailand) and its sympatric species Rana cf. chloronota (previously reported as Rana livida) (Stuart et al., 2006a). Until now, the distribution of Odorrana aureola was known only from Phu Luang Wildlife Sanctuary and Phu Kradueng National Park (Figure 2). During a herpetological survey in 2006, we conducted a ield survey in the area of Phetchabun and Uttaradit Provinces. From these areas, we obtained seven specimens which were assigned to Odorrana aureola by using morphological characters compared to type specimens (see Stuart et al., 2006b) and original description. The specimens were catalogued and kept at the collection of the Thailand Natural History Museum (THNHM), Pathum Thani, Thailand. Information of these voucher specimens are as follows: THNHM 13101-13102 (ield tags Y 0017-18, two adult females), collected by Y. Chuaynkern, C. Inthara and R. Songchan in 18 July 2006 from Phu Soi Dao Waterfall, Phu Soi Dao National Park, Nam Paad District, Uttaradit Province; THNHM 13103-13104 (ield tags Y 0076-77, two adult females), THNHM 13105-13106 (ield tags Y 0078-79, two adult males), collected by Y. Chuaynkern, C. Inthara, R. Songchan and Chamlong Insorn in 21 July 2006 from Sai Thip Waterfall, Phu Soi Dao National Park, Nam Paad District, Uttaradit Province; THNHM 13107 (ield tag Y 0269, an adult male), collected by Y. Chuaynkern in 17 July 2006 from Phu Hin Rong Kla National Park, Nakhon Thai District, Phetchabun Province (Figure 1).
