Apparently the sister-species of the Narrow-billed Woodcreeper (Lepidocolaptes angustirostris) of eastern South America, the White-striped Woodcreeper is endemic to western and southern Mexico. It is a slim-bodied, small-medium-sized woodcreeper with a slender, curved bill. Principally warm brown above, both the head and underparts are heavily streaked with white on black, although the throat and cheeks are unmarked bright white. The White-striped Woodcreeper is largely found in subtropical and temperate woodlands above 900 m, although it occasionally ranges much lower, and it is frequently associated with mixed-species flocks. Insects form the greater percentage of its diet.
