한국산 달팽이과 15종의 외부형태 분석

Morphological Analyses of 15 Species of Bradybaenidae in Korea

These studies were conducted to compare the external morphologies of 15 species of land snails in 8 genera of family Bradybaenidae in Korea. Principal component analyses of 15 species can be divided into five groups based on the morphological characters and the result of cluster analyses were in accord with the principal component analyses. The morphological intraspecific similarity of Nesiohelix samarangae of Mitan and Cheju population(S=0.999) proved to be highest. The degree of interspecific similarity between Aegista(Plectotropis)divesa and Aegista(plectotropis)quelpartensis(S=0.970)were more similar than the other interspecies.
