Remarks. Regarding the collection locality of DMNH 12866 [Sta. Librada (Sarare)], there are places called Santa Librada in Quindío, Tolima, Vichada, and Cundinamarca. However, several reasons lead us to believe that the location in question is in the eastern plains of Colombia, and probably in Norte de Santander: (1) all other confirmed Colombian records for this species, and most of the species of Dryptus come from the lowlands of that region, and from Venezuela; (2) this species has not been collected in Quindío, Tolima or Cundinamarca; (3) a region known as “región del Sarare” in the Cordillera Oriental (Eastern Range of the Andes), and “Sarare, Santa Librada, 1300–1600 m ” are localities from which paratypic collections of ferns, Danae betancurii A. Rojas, 2009 have been reported ( Rojas-Alvarado 2009a). Thus, we place lots labeled Santa Librada and Santa Librada (Sarare) within Norte de Santander. We are aware that there is a Santa Librada in Vichada, and a location called El Sarare in Arauca within ~ 150 km of each other, both at less than 200 m of elevation. Of note is that if Rochereau’s actual collection localitites were in Arauca/Vichada, they would still be consistent with a distribution of this species in the eastern plains of Colombia, including equivalent elevations. Likewise, there are several locations called Támara, or Tamaná, in various departments of Colombia (Casanare, Boyacá, Tolima); we consider that it is more likely either Quebrada Támara, or Cerro Tamaná, both in Norte de Santander.

In addition to the Venezuelan distribution indicated here, Tello (1975) listed Puerto Cabello (Edo. Carabobo), and Edo. Trujillo as localities for this species.
