Remarks

Of the know species our specimen is most similar to Flabelligena gascognensis AGUIRREZABALAGA & CEBERIO 2006 from the Capbreton Canyon (Bay of Biscay, NE Atlantic) by possessing 3 pairs of branchiae, but differs by not having anterior region of the body diverging into Y- shape, by the from of papillae and by having only 1-2 falcigers instead of 2-4.
