Dichomeris vindex is almost identical to setosella except for the forewing PM/ST line being mostly straight or broadly curved with bend toward the apex at the costa. The forewing PM/ST line of setosella is usually sinuous, particularly at middle of wing, and has tendency to bend toward base at the costa. The ranges for the two species largely overlap, however D. vindex is not found east of the Appalachian Mountains. (2)

Dichomeris bilobella is very similar to both D. setosella and D. vindex, however it is more of a dark bluish gray overall and dark spots and lines are typically bordered with light-yellow to pale orange scales. As in vindex, the PM/ST is waved medially and angled toward the apex on the costal margin. (2)
