It is found in Argentina, Brazil, and Paraguay. == Taxonomy and systematics == The speckle-breasted antpitta has a complicated taxonomic history. It was originally described in 1937 as Grallaria natteri. Soon it was realized that it and several other species did not belong in Grallaria so genus Hylopezus, which had earlier been merged into Grallaria, was resurrected for them. By the middle of the century the speckle-breasted antpitta had been reallocated as a subspecies of the white-browed antpitta (Hylopezus ochroleucus). A 1995 publication showed that it should again be treated as the species Hylopezus natteri. A 2019 publication showed that Hylopezus was paraphyletic with respect to two other genera and that the speckle-breasted antpitta properly belonged to none of them. The authors erected genus Cryptopezus for it. The speckle-breasted antpitta is the only member of its genus and has no subspecies. == Description == The speckle-breasted antpitta is about 13.5 to 14 cm (5.3 to 5.5 in) long; two males weighed 31 and 33 g (1.1 and 1.2 oz).
