San Carlos del Río Negro, Spruce H31c ( lecto- , designated by Meenks [1987] , MANCH[MANCH-cc1817], fide Gradstein & Reeb 2018b ). REMARKS Riccardia leptophylla is a delicate, widespread neotropical species that was recorded from Guadeloupe (“Cascade Écrevisses, De Sloover 23.544, JE) by Meenks (1987) . We have not seen this material but have visited the Guadeloupean locality several times and only found R. regnellii there. We therefore assume that the R. leptophylla material from Guadeloupe belongs to R. regnellii .
