DEFINITIONS

CERCOMACRA
(Thamnophilidae; Ϯ Rio de Janeiro Antbird C. brasiliana) Gr. κερκος kerkos  tail; μακρος makros  long; "GENUS VI. CERCOMACRA.  Statura major: ptilosis magis unicolor: forma validior: rostrum ad basin dilatatum: cauda longa e rectricibus plerumque decem multum graduatis: acrotarsiis divisis, paratarsiis integris.  These birds form a transition between Formicivora and Pyriglena. I have sometimes been inclined to unite them to the latter; but they differ in their broad flattened bill, which in Pyriglena is compressed throughout.   1.

Gray Antbird (iterata)
SCI Name: Cercomacra cinerascens iterata
iterata / iteratus
L. iteratus  repeated  < iterare  to repeat  < iterum  again.
● "Most closely resembling Saltator aurantiirostris bolivianus Chapman [= syn. Saltator aurantiirostris hellmayri] of the Temperate Zone in Bolivia, the black areas on the breast and sides of the throat as in that race" (Chapman 1927) (subsp. Saltator aurantiirostris).
● "Most nearly resembling Hemispingus frontalis ignobilis (Sclater) of the Subtropical Zone of western Venezuela but entire underparts with a stronger ochraceous tone, this difference particularly pronounced on the abdominal region. Similar to Hemispingus frontalis hanieli Hellmayr and Seilern of the Subtropical Zone of north-central Venezuela but more yellow throughout, the upperparts greener" (Chapman 1929) (subsp. Sphenopsis frontalis).
