cellule elongatze, angustve, marginem versus incrassatæ, lumine angustissimo, 
limbum inferne latiusculum hyalinum superne tenuiorem, ultra medium evanidum 
efformantes, alares numeros:e, subquadrat:e, rubree, in ventrem distinctum dispositze. 
Cetera ignota.

Endemic. 
Species cum Campylopode griseo, Hornsch., comparanda, sed statura multo robustiore, 
foliis strictipilis, integris, tubulosis, limbatis facillime dignoscenda.
