Paita, Piura, north-west Peru.
Appears to be closely related to L. albolineatus. Recent reconstructed DNA-based phylogeny#R indicates existence of genetic structuring among populations of this woodcreeper, suggesting that Mesoamerican and South American forms represent two distinct species and that further splits may be valid; however, samples are generally too small for positive conclusions to be drawn, and further work needed. Otherwise, races lineaticeps, littoralis and uaireni poorly differentiated from one another, whereas nominate and esmeraldae appear to represent extremes in a cline. Assessment of geographical variation complicated by marked individual and age-related variation in size, in width and extent of streaking above and below, in shade of upperparts, and in intensity of buff coloration on throat and underparts. Birds from SE Mexico to N Honduras often recognized as race insignis, said to differ from compressus in deeper buff throat and broader streaking both above and below, but neither character seems geographically related; variation in Middle America most evident as cline of decreasing size from N to S. Seven subspecies recognized.
