台灣一對受精囊之新紀錄種蚯蚓

A New Record of the Bithecal Megascolecid Earthworm Amynthas papilio (Gates) (Oligochaeta) from Taiwan

This paper reports a new record of the megascolecid earthworm Amynthas papilio (Gates, 1930) from Taiwan. It was originally described from Burma, and also reported from the Riukiu Islands of Japan. In our recent earthworm survey in the northern Taiwan, A. papilio was collected in the grass fields with rich soil at the campus of National Taiwan University and Hsin-Chu Girl High School. As it occurs at human disturbed habitat associated with urbanization, we suspect it as an exotic species introduced recently from Southeast Asia. 本文描述一巨蚓科（family Megascolecidae）台灣新紀錄種蚯蚓 Amynthas papilio（Gates, 1930）。此種蚯蚓首次在緬甸被記載，同時在日本的琉球群島也有紀錄。在北台灣，我們首次在台灣大學及新竹女中的校園草地中發現，由於它出現在人類活動頻繁的都市棲地中，因此我們推斷該蚯蚓應是由南亞洲遷徙而來。
