Abstract

To clarify the key characteristics of Korean brown frogs (R. dybowskii, R. huanrenesis and R. amurensis coreana), this study employed a morphological and morphometrical comparisons among brown frogs found in Korea and Japanese endemic species, R. tsushimensis. As a result, it was considered that the key characteristics were the shape of the finger and toe tips, the markings of the lower jaw, the presence or absence of an upper lip line, the development of toe webbing, and the shape of the vomerine teeth series by morphological comparisons of brown frogs. Also, there were significant differences in tympanum diameters and foot lengths of the four species of brown frogs. Therefore, a comparison between morphological and morphometric characters is an effective way to clarify the identification of brown frogs.

한국산 산개구리류 3종의 분류학적 형질을 명확히 하기 위하여 형태학적, 계량형태학적 방법을 이용하여 한국산 산개구리류 3종(북방산개구리, 계곡산개구리, 아무르산개구리)과 일본산 산개구리류 1종(R. tsushimensis)을 비교 분석하였다. 형태학적 비교 분석결과, 산개구리류는 손가락 끝과 발가락 끝의 모양, 아래턱에 형성된 반문의 발달유무, 윗입술선의 유무, 물갈퀴의 발달 정도, 서구개치열의 형태 등이 차이가 있는 것으로 확인되었으며, 계량형태학적 분석을 통하여 고막의 직경과 발길이의 차이를 확인할 수 있었다. 따라서, 이러한 형태학적, 그리고 계량형태학적 특징은 한국산 산개구리류를 동정하는데 매우 유용한 형질이라고 생각된다.
