Abstract

The megascolecid earthworms of the Phu Quoc island are intensively investigated. Twelve species in three genera (Lampito Kinberg, 1867, Amynthas Kinberg, 1867, and Metaphire Sims & Easton, 1972) are recorded. Of these, Metaphire doiphamon Bantaowong & Panha, 2016 is recorded for the first time in Vietnam, and three species are newly described, namely Amynthas catenatus sp. nov., A. phuquocensis sp. nov., and A. poropapillatus sp. nov. An identification key to 12 megascolecid species is provided as well.
