摘要

This paper describes the moniligastrid earthworm Drawida barwelli (Beddard, 1886) as a new record from Taiwan. It is a small earthworm originated from Southeast Asia. It was collected from coastal plains and hills below 1000 m in elevation in central, southern and Hualien and Taitung (including Lanyu) counties in eastern Taiwan, and has never been found in northern Taiwan. Its occurrence in Taiwan reported herein constitutes the island as the northern extremity of the distributional range of this peregrine species.

本文描述一原產於東南亞之新紀錄種蚯蚓巴氏杜拉蚓Drawida barwelli（Beddard, 1886）。其為小型蚯蚓，屬於鏈胃蚓科（Moniligastridae）杜拉蚓屬（Drawida），在台灣中南部及東部花東地區（包括蘭嶼）海拔一千公尺以下的海岸平原至丘陵地帶均有分布，北台灣則未曾有採集紀錄，顯示台灣應為此廣布種蚯蚓分布範圍之北界。
