Thirty-six species of Riccardia are recorded from the tropical Andean region of Venezuela, Colombia, Ecuador, Peru and Bolivia. An identification key to the species is provided along with notes on the taxonomy, distribution and ecology of each of them. Riccardia paramorum spec. nov. is a submerged species from páramo lakes in the Colombian East Cordillera. Two new varieties have been described too: Riccardia capillacea var. dentata and R. hansmeyeri var. dentata. Eight species were transferred from Aneura to Riccardia, while eight other species were reduced to synonymy.
