Comment

Chan-ard, 2003, Photograph. Guide Amph. Thailandezembed: 72, provided a very brief account, map for Thailand, and photograph. Das, Jankowski, Makmor, and Haas, 2007, Mitt. Hamburg. Zool. Mus. Inst., 104: 165, provided a brief description for Sarawak. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583 (see comment in Amphibia record) suggested on molecular grounds that Caudacaecilia asplenia is imbedded within a paraphyletic Ichthyophis. Chan-ard, Cota, and Makchai, 2011, Amph. E. Region Thailand: 123, provided the La Doo Tin Mine, Yala, Thailand record. Poyarkov, Nguyen, Popov, Geissler, Pawangkhanant, Neang, Suwannapoom, and Orlov, 2021, Russ. J. Herpetol., 28 (3A): 68, suggested that the Thailand record requires confirmation. McGrath-Blaser, Grafe, Torres-Sanchez, McLeod, and Stuart, 2025, J. Nat. Hist., London, 59: 29–43, discussed cutaneous biome and provided a genetically-confirmed record from Ulu Temburong National Park, Brunei.
