The species then occurs, more or less con- tinuously, from Narifio, southern Colombia, south on the Pacific slope and interandean plateau through Ecuador to northwestern Peru (A. r. spodionotiis south to central Ecuador where it intergrades with A. r. coniptus of farther south). On the Ama- zonian slope of Ecuador there are records from the north in the vicinity of Papallata, but for the next 250 kilometers the species is absent; it reappears in Azuay, as the race latimicluis, and is common from here south- ward well into Peru. It is almost certain that the distributional gap is real and not a collecting artifact; several areas within the gap have been well-collected (see Payn- ter and Traylor, 1977:138). In northern Peru A. r. comptus occurs on the western slope in Piura and is replaced farther south by A. /•. chugurensis. On the eastern slope A. r. latinuchus reaches Ama- zonas and A. r. J)aroni is in southern Caja- marca and Libertad, just entering the Pa- cific di-ainage west of the upper reaches of.
