Records of Estuarine Tubificidae (Oligochaeta) from Taiwan

Abstract

Five species of Tubificidae are reported from the Tan Shui and Shuang Hsi estuaries in northern Taiwan : Doliodrilus tener Erseus, Monopylephorus rubroniveus Levinsen and M. limosus (Hatai) from a salinity range of 12-32‰, and Branchiura sowerbyi Beddard and Limnodrilus hoffmeisteri Claparede, both primarily freshwater forms, from oligohaline reaches (1-2‰ salinity) of highly polluted rivers. A find of D. tener at Kin Men Island near mainland China is also recorded.
