Abstract:
Internasal bones have generally been recorded in teleostean and tetrapod fossils, being absent in most extant vertebrates. Presently, there has been one case of the internasal bone discovered in a living salamander, Pseudohynobius puxiongensis (Caudata: Hynobiidae). The second case discovered in living salamanders is reported in this article, which is present in one of five specimens of Hynobius maoershanensis, a species endemic to China. This case is again regarded as individual variation. Thus, the presence of an “internasal bone” may represent intraspecific variation and is thus a misleading taxonomic character.
