| The two species display similar body length and segment number as well as show resemblance in the shape of the clitellum and tubercula pubertatis. |
| Juveniles were distinguished from adults by size and the absence of a clitellum, and the adults identified. |
| A clitellum is present in the mid-region during the reproductive period. |
| The saddle is also known as the clitellum, and it forms a cocoon that holds eggs and nourishes a worm until baby worms hatch. |
| Clitellum slightly resembling this of amphius, although on various individuals it was variably developed, unequally encircling segments ventrally. |
| Between segments 32 and 37 is the clitellum, a slightly bulged, discoloured organ that produces a cocoon for enclosing the earthworm's eggs. |
