Jirkov said that the second and the third pairs of branchiae have at least 4 filaments at each side and that these originate directly from the body surface, while the Swedish specimens have almost twice that number of branchial filaments on each side of second and third pairs of branchiae, and those originate from cushion-like, apparently glandular areas.

However, Holthe (1986) did not specify from which locality in Scandinavia came the material he examined, his redescription does not describe in detail characters such as the morphology of the lips, branchiae and notochaetae, and yet there are some discrepancies between his redescription and that provided above. Holthe’s specimens have fewer branchial filaments, at least 7 pairs on segment 2 and 4 pairs on segments 3 and 4, and they have nephridial and genital papillae on segments 3–7, which is rather unusual for a thelepodid, as those papillae, if visible, are always on segments 4–7, among all the animals belonging to this family (
