Abstract: | A new genus, Pseudokuhnia, is established for Kuhnia minor, family Mazocraeidae. It differs from Kuhnia in the presence of two dorso-lateral vaginae, supported by surface ridges; differently shaped large genital hooks, large hamuli and ovary; an opisthaptor which is ventral to and well separated from the body proper; and a rudimentary antero-supplementarium of the clamps. The Atlantic population of P. minor differs from the Pacific population mainly in the larger size of the hamuli and the smaller size of the large and small genital hooks. |
