Antímano, near Caracas, Distrito Federal, Venezuela.
Until recently considered conspecific with Z. improbus, but molecular and acoustic evidence#R combines with morphology to suggest otherwise: differs in its dull grey-olive vs olive crown and ear-coverts (2); pure grey vs olive-grey flammulated breast (1); creamy-white vs yellowish belly (2); “distinct” song#R, supported by limited online material for improbus which, if typical, reveals absence of gradual frequency drop (2)#R (confirmatory research needed). Monotypic.
N Venezuela from S Lara and Yaracuy E to Distrito Federal and Miranda.
