Pronophiline butterflies (Satyridae) of the Serrania de Valledupar, Colombia–Venezuela border

Abstract. The thirty-one species of the tribe Pronophilini found by the authors in the little-known mountain range on the northern borders of Colombia and Venezuela, the Serrania de Valledupar, are listed. Their recorded altitude limits are given, as well as notes on their habits and behaviour. The existence, among twenty of the species, of series of two or three closely related congeners replacing one another up the altitude gradient, is commented upon. Two cases of mimicry between species from different genera are reported. One new genus, fourteen new species and one new subspecies are described. Two new synonymies are established, the status of one taxon revised, and new status given to another.
