André (1928) mentioned this species among algae, sponges and bryozoans from Mediterranean Sea. Remarks: Bartsch (2020) mentioned that the specimens identified to L. falcata from 2500–3000 m depth would be distinct from L. falcata and those from 400–500 m depth at Golfe de Gascogne (Trouessart & Neumann 1896) were also dubious. This species was reported on various substrates: coarse sands, gravels, shell fragments, sediments with algae, mussels, bryozoans, hydroids, ascidians, and lichens ( Abé 2021 ).
