- Characteristic traits, all apomorphies, are perichaetine setae, tubulo-racemose prostates, avesiculate meroic nephridia and opisthogastry (the development of intestinal gizzards, which in this genus are multiple in the region of segments 20–26).

- Due to the somewhat macerated specimens Michaelsen (1933) was not able to recognize the structure of the excretory system in the type species, however, he found it meroic at W. beauforti.

- The genus Ramiellona was erected by Michaelsen (1935) to include Ramiellona stadelmanni Michaelsen, a meroic species from Honduras with acanthodrilin male terminalia, tubular prostates, one gizzard and with internal calciferous lamellae.
