Taxonomy..

The tapaculos were traditionally placed in a distinct family Rhinocryptidae; more recent research (Irestedt et al. 2002, Rice 2005a,b) indicates that according to analysis of mt and nDNA sequence data, the tapaculos might be better merged into the Formicariidae as tribe Rhinocryptini, as they are closer to the antthrushes than either is to the true antpittas.

Alternatively, the latter might be raised to family status. In this case, it would be possible to maintain the tapaculos as a separate family too, but it would seem altogether more warranted to consider them a subfamily of the Formicariinae sensu stricto, which would be called Rhinocryptinae.

Whether this latter approach, the placement as a tribe in a tapaculo-antthrush Formicariinae subfamily, or maintenance as a separate family is to be preferred depends on whether the true antpittas are closer to the tapaculos and true antbirds, or rather to the Pittasoma "gnatthrushes" and other gnateaters and the true antbirds. There are some, albeit very tentative, indications that the latter may indeed be the case, which would be reflected in the placement of the tapaculos as subfamily Rhinocryptinae, with the Formicariinae being restricted to the true antthrushes (Rice 2005a).

It must be noted that apparently not all tapaculo genera would have to be moved to the formicariids (Irestedt et al. 2002). As the type genus Rhinocrypta certainly would, any distinct genera (such as the peculiar crescent-chests) would need a new family name.
