Drepanolejeunea fragilis Bischl. ex L.Söderstr., A.Hagborg et von Konrat , sp. nov.

Diagnosis (translated from Bischler 1964):—Similar to D. araucariae but stems are fragile. Ocelli one, median or basal, or 2, one median and one basal, rarely with two adjacent ocelli. Lobule regularly swollen, with a dorsal wing attached to the lobe, with a long tooth at its tip, which sometimes crosses the apical tooth. The lobule does not extend along the ventral margin of the lobe. Leaves with rudimentary lobules frequent. Amphigastria small, with 14–18 cells at maximum. For further description and illustration, see Bischler (1964).
