Garbar A.V., Vlasenko R.P.
Abstract. The karyotypes of Aporrectodea caliginosa, A. rosea, and A. longa werestudied. 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 variations of chromosome number were noted within the same preparation.
