The characteristics of egg sacs of Hynobius leechii in Narodo, Boseong, Jirisan, and Suwon populations and of H. yangi and H. quelpaertensis in Busan and Jeju population, respectively, were compared with each other. The results showed that the length and width of egg sacs and the length of the whiptail-like structure at the end of egg sacs were highly varied among the populations and among the different species. In special, the egg sacs of H. leechii in Narodo and Boseong populations lacked of the whiptail-like structure at the end of the egg sacs, which readily distinguished the populations from other populations. The presence and absence of the whiptail−like structure at the end of egg sacs in H. leechii might be responsible for potentially additional speciation in genus Hynobius. It is needed to be more investigated about the possibility.
