Notes on Metaphire multitheca (Chen, 1938) (Oligochaeta, Megascolecidae) recorded from Vietnam, with descriptions of two new species

The paper deals with Pheretimamultithecamultitheca Chen, 1938 recorded from Vietnam (non Pheretimamultitheca Chen, 1938 now in Metaphire from Hainan Island). As a result, a new species, Amynthaserroneous sp. n., is revealed from materials which were previously misidentified as Pheretimamultithecamultitheca. The new species is obviously distinguished from other Amynthas species by multiple sperm...
