This species of chlorospingus has a very restricted distribution in eastern Panama and immediately adjacent Colombia. Tacarcuna Chlorospingus takes its name from Cerro Tacarcuna, which straddles the border between Panama and Colombia; this is the only locality at which this species occurs in South America, but it occurs west, very locally, to central Panama. As is typical of the genus, this chlorospingus occupies humid montane forests, generally between 800 and 1500 m, and inhabits mainly the lower and middle strata in cloud forest. Also like other species of chlorospingus, this species typically is found in small flocks, which frequently mix with those of other species. Principally yellow below and olive above and on the head, Tacarcuna Chlorospingus has conspicuously irides, which should immediately distinguish the species.
