Distribution: Medium to high altitudes in extreme southwestern Venezuelaand extreme northeastern Colombia(ssp. costarum), East Cordillera of Colombia(ssp. semiramis), northern Central Cordillera of Colombia(ssp. belmira), southern Central Cordillera of Colombiaand northern and central East Cordillera of Ecuador(ssp. palla), and southcentral (Azuay) and southern (Loja and ZamoraChinchipe) Ecuador(ssp. willmotti). In order to preserve the stability of nomenclature by selecting one specimen as the unique bearer of the name, and following Art. 74.7 of the Code, we designate as lectotypeof Euterpe semiramisLucas, 1852the male syntypein MNHN from " Colombia", which was labelled as "Lectoholotype" by J. H. Robert [examined]. Up to 1998, Ecuadorian C. semiramisspecimens were all regarded as belonging to ssp. pallaBrown, 1939. Eitschberger & Racheli (1998)described ssp. salomonfrom Ecuador, SantiagoMorona. At that time, very few Ecuadorian specimens were known. Since then, we have examined a total of 30 Ecuadorian individuals (including relevant types), 24 of them referable to ssp. palla. That material has allowed us to determine that ssp. pallais characterized by a dark pattern which varies clinally in intensity from north to south, darker specimens occurring at the southern limit of its distribution, where they match the phenotype described as ssp. salomon. Thus, we regard salomonas a new synonymof palla. On the other hand, we examined six specimens recently collected in southern Ecuadorand clearly belonging to a new taxon, which we describe below.
