South American species of the freshwater copepod genus Boeckella are distributed in the Andean region, which corresponds to southwestern South America below 30° south latitude, also extending along the Andean highlands north of this latitude, and comprises the Subantarctic, Central Chilean, Patagonian, and Paramo-Puna subregions. Based on a track analysis, five generalized tracks were found: Subantarctic (involving some Subantarctic islands, the Falklands, Tierra del Fuego, and the southern portion of continental Chile and Argentina): B. brevicaudata, B. poppei, B. vallentini, and B. michaelseni; Patagonian (in the southern Patagonia plateau): B. brasiliensis, B. silvestrii, and B. longicauda; Mid-southern Andes: B. gibbosa and B. diamantina; Paramo-Punan (in the central and northern Andes, from northwestern Argentina to western Colombia): B. calcaris, B. palustris, and B. occidentalis; and Neotropical (mainly in the Neotropical region, but reaching also Patagonia and the Puna): B. meteoris and B. bergi. Two nodes have been determined: one in southern Chile and Argentina, where the Subantarctic, Patagonian, and Neotropical tracks intersect, and the other in the central Andes, where the Paramo-Punan and Neotropical tracks intersect.
