Remarks. Sims & Easton (1972) stated that the species can be excluded from Metaphire or Pheretima because of the absence of copulatory pouches, but it cannot be assigned to a genus due to lack of details of the presence or absence of intestinal caeca. Therefore, it was listed as "species incertae sedis " on page 241 of Sims & Easton (1972). The examined population in Vietnam showed the presence of intestinal caeca in xxi–xxvii. The species is confirmedly assigned to the genus Amynthas .
