Subspecies
Genus may be most closely related to Margarops. Contrary to earlier opinion, appears not to be close to Ramphocinclus. Probably forms a superspecies with Grey Trembler (Cinclocerthia gutturalis), and previously considered conspecific. Subspecies tremula possibly merits treatment as a separate species.
Proposed subspecies pavida (St Kitts) and sola (Montserrat) considered indistinguishable from that subspecies.
