BirdLife International's Handbook of the Birds of the World (HBW) retains it in Philydor.
According to the IOC and Clements, the chestnut-winged foliage-gleaner shares genus Dendroma with the buff-fronted foliage-gleaner (D. rufa), and they and the chestnut-winged hookbill (Ancistrops strigilatus) are sister species. HBW retains the buff-fronted foliage-gleaner in genus Philydor with the chestnut-winged and several other foliage-gleaner species, and does not agree with the above sister species treatment.
The three taxonomic systems agree with assigning two subspecies to the buff-fronted foliage-gleaner, here listed using genus Dendroma. (HBW retains the neuter spellings of the specific epithets instead of... Wikipedia →

Rare
Under 5% of wildlife watchers report a Chestnut-winged Foliage-gleaner sighting in Yasuní National Park on a given day, based on 37 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 415th most-seen of the 533 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Chestnut-winged Foliage-gleaner in Yasuní National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Chestnut-winged Foliage-gleaner sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 parks where we can rate Chestnut-winged Foliage-gleaner sightings, Yasuní National Park ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Tambopata National Reserve (Peru, under 5%) and Manu National Park (Peru, under 5%).
GBIF citizen-science records
It is estimated from how often the Chestnut-winged Foliage-gleaner is recorded against all the birds logged in Yasuní National Park (37 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.
