Abstract
Two new species of Tubificinae (Oligochaeta: Naididae), Tubifex conicus n. sp., and Isochaetides palmatus n. sp., are re-ported from Tibet, China. T. conicus is unique in the genus by having spindle-shaped atria, large prostates and symmetri-cally conical penial sheaths. I. palmatus differs from its allies by possessing palmate dorsal chaetae, pectinate ventral chaetae and no penial sheaths.References
