The spot-backed antshrike was described by the French ornithologist Louis Pierre Vieillot in 1816 and given the binomial name Thamnophilus guttatus. The genus Hypoedaleus was erected by the German ornithologists Jean Cabanis and Ferdinand Heine in 1860 with the spot-backed antshrike as the type species. The name of the genus is from the Ancient Greek hupoidaleos meaning "somewhat swollen". The specific epithet is from the Latin guttatus meaning "spotted" or "speckled".
The spot-backed antshrike is the only member of genus Hypoedaleus and it has no subspecies. The spot-backed antshrike is a large antbird, 20 to 21 cm (7.9 to 8.3 in) long.

GBIF citizen-science records
It is estimated from how often the Spot-backed Antshrike is recorded against all the birds logged in Iguazú National Park (1,669 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
