Common Name
Type Locality Río Tumbes, Cabo Inga (3°58'00''S, 80°24'59''W), Tumbes, Peru.
Etymology A combination of Greek 'Para' - near or beside, Cetopsis - indicating that this genus is similar to Cetopsis, but sufficiently different to warrant its own genus. The species name, atahualpa, is in reference to Atahualpa who reigned from 1515 to 1533 as the last ruler of the Inca Empire that encompassed the region from which the population samples of this species originated.
