蘭嶼蚯蚓相

Earthworm Fauna of the Lanyu Island (Botel Tobago)

A total of nine species of terrestrial earthworms were collected at 14 localities on the Lanyu Islandon 16 and 17 April 2000. They were Pontoscolex corethrurus (Müller) of the family Glossoscolecidae,and Amynthas aspergillus (Perrier), Amynthas corticus (Kinberg), Amynthas gracilis (Kinberg),Amynthas lautus (Ude), Metaphire californica (Kinberg), Pithemera bicincta (Perrier), Pithemeralanyuensis Shen and Tsai, and Polypheretima elongata (Perrier) of the family Megascolecidae. Of themP. lanyuensis is an autochthonous (endemic) species of the island, whereas the other eight species arelikely the anthropochorous (exotic) species which were introduced later to the island by native Tao fromthe Philippines or recently by Chinese from Taiwan. 於蘭嶼的蚯蚓採集中共採得九種陸生蚯蚓，分別為Pontoscolex corethrurus（Muller）、Amynthas aspergillus（Perrier）、 Amynthas corticus（Kinberg）、 Amynthas gracilis（Kinberg）、 Amynthas lautus（Ude）、Metaphire californica（Kinberg）、Pithemera bicincta（Perrier）、Pithemera lanyuensis Shen and Tsai 以及Polypheretima elongata（Perrier）。其中除了 P. lanyuensis為原生種，其餘八種蚯蚓均為經由人類活動而帶入島上的外來種。
