Similar species:
Ichthydium monolobum was included in this species
Particularities:
Very characteristic furca
Fundorte:
The species I. (F.) forficula was united some time ago with the somewhat smaller species I. monolobum into a single species. A main characteristic of this species are the long, curved and thin glue tubes, which give the animals a “tweezer-like” appearance:
I. forficula: dorsal with pincer-like adhesive tubes
On the ventral side the animal carries two distinct terminal plates.
I. forficula: ventrale Terminalplatten
The lash bands are broken up into individual clumps of extremely long lashes.
I. forficula: Ciliate tuft
In the side view, you can see the enormous length of the locomotive eyelashes:

The posterior tactile hairs are on a papilla:
