摘要

本文描述4種產於合歡山區海拔2300至3200公尺的遠盲蚓：其中1種為亞種，另3種為新種。分別為Amynthas exiguus aquilanius subsp. nov.、A. catenus sp. nov.、A. proasacceus sp. nov.以及A. wulinensis sp. nov.。A. exiguus aquilonius為產於緬甸的A. exiguus exiguus（Gates）之亞種，而A. catenus及A. proasacceus則分別與產於海南島的A. manaserialis（Chen）及A. asacceus（Chen）有密切相關。顯見臺灣本島高山地區之陸生蚯蚓相與南中國及東南亞之蚯蚓相有較密切的相關性，而與中國溫帶地區的種類不同。

This paper describes 1 new subspecies and 3 new species of terrestrial earthworms belonging to the genus Amynthas (Oligochaeta: Megascolecidae) from Mt. Hohuan on the subtropical island of Taiwan from a region at elevations of 2300 to 3200 m with a cold-temperate climate. They are Amynthas exiguus aquilonius subsp. nov., A. catenus sp. nov., A. proasacceus sp. nov., and A. wulinensis sp. nov. Of these 4 new forms, A. exiguus aquilonius is conspecific to A. exiguus exiguus (Gates) of Burma, while A. catenus and A. proasacceus are closely related, respectively, to A. monoserialis (Chen) and A. asacceus (Chen) of Hainan Island, China. The endemic terrestrial earthworm fauna in this cold-temperate mountain region of Taiwan is apparently more closely related to those of tropical southern China and Southeast Asia than to that of cold-temperate central China.
