This paper describes two megascolecid earthworms Pontodrilus litoralis (Grube, 1855) and Metaphire houlleti (Perrier, 1872), and a lumbricid earthworm Eiseniella tetraedra (Savigny, 1826) as the species newly recorded to Taiwan. P. litoralis is a small, euryhaline earthworm dwelling in the intertidal zone along coasts of the Penghu island and the southwestern Taiwan. M. houlleti is a medium, sexthecal earthworm from Pingtung of the southern Taiwan. It belongs to the houlleti-group of the genus Metaphire Sims and Easton, 1972.
