摘要

The distribution of the recently described Rhacophorus aurantiventris was thought to be restricted to the type locality in the northern Taiwan. However, four specimens, including the first female, of this species were collected from Chihben, Taitung Co., eastern Taiwan, on May 23, 1995. This seems to indicate that R. aurantiventris exhibits a pattern of fragmented distribution within Taiwan. Results of comparisons of male and female specimens suggest the possible presence of sexual dimorphism in body size, nuptial pad condition and spinule distribution on the dorsum, but not in coloration.

橙腹樹蛙過去只發現在宜蘭縣與臺北縣交界的哈盆地區，然而最近卻在台東縣知本山區採獲四隻標本，顯示其零碎分佈的現象，值得重視其保育問題。比較雌雄標本的外形發現兩性問可能存在體型大小、婚墊及背部粉刺狀突起分佈的雙型性。
