The affinities of the monospecific genus Euthlypis are still unclear, although it is sometimes subsumed within Basileuterus, and some authorities have pointed to structural similarities with the Yellow-breasted Chat (Icteria virens). The single species, the Fan-tailed Warbler, is a distinctive bird found from northern Mexico south to northwest Nicaragua, with largely grayish upperparts, a black foreface, white lores and tip to the tail, and yellow underparts becoming white ventrally. Fan-tailed Warblers are inhabitants of submontane and lower montane forests from close to sea level to approximately 1800 m, always in areas with an undisturbed understory. Fan-tailed Warblers follow army ants, taking insects fleeing from the swarm, and they sometimes also follow Nine-banded Armadillos (Dasypus novemcinctus), for similar reasons.
