        abstract = {The karyotypes of Aporrectodea caliginosa, A. rosea, and A. longa were studies. The diploid sets of chromosomes comprise 18 pairs of two-armed chromosomes (FN=72) in each species. A triploid form was discovered in A. rosea (3n=54, FN=108). Considerable variation of chromosome number were noted within the same preparation.}
