  • The lacertid lizard Takydromus wolteri widely distributed in South Korea, but intraspecific diversity of this species was not almost studied. T. wolteri represented by 8 specimens collected from 5 localities were analyzed by the Randomly Amplified Polymorphic DNA (RAPD) method with 28 random decamer primers and the phenogram constructed by using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) method based on RAPD data. The populations of T. wolteri using in this paper were collected from Gyeonggi-do, Chungcheongbuk-do, Jeju-do, Jeollanam-do and Gyeongsangnam -do in South Korea. Among 68 different bands detected in RAPD analysis, 59 bands (87%) showed polymorphism. The phenogram showed that the populations of T. wolteri were grouped into two. These results suggest that T. wolteri were supported intraspecific diversity.

  • A specimen (862.3 mm standard length) of Pisodonophis cancrivorus (Richardson, 1848), family Ophichthidae, was first collected from the coast of Uljin-gun in Gyeongsangbuk-do, Korea in September 2008. This species is characterized by the following: fleshy protrusions of upper jaw in the front and rear of the posterior nostril, 3~5 irregular rows of granular teeth in bands on maxilla, mandible and vomer, and origin of dorsal fin above the middle of the pectoral fin. Based on the fleshy protrusions found on its upper jaw, a new Korean name "dol-gi-ba-da-baem" has been proposed for this species.
