The spot-crowned woodcreeper (Lepidocolaptes affinis), is a passerine bird in the subfamily Dendrocolaptinae of the ovenbird family Furnariidae.

Adults of the nominate subspecies L. a. affinis have a dusky face and sides of the neck with a black malar stripe.

Their crown and nape are dark brown with conspicuous buffy spots or diamonds that sometimes extend as thin streaks onto the upper back.

Their underparts are olive-brown with wide black-edged buffy streaks beginning on the lowest part of the throat that fade on the flanks and undertail coverts.

L. a. neglectus is browner (less olivaceous) than the nominate, with a deeper buff throat and wider and paler, almost whitish, streaking on its underparts.

Subspecies L. a. lignicida is the northernmost; it is found in the northeastern Mexican states of Nuevo León, Tamaulipas, and San Luis Potosí.

The nominate L. a. affinis is found from southern Mexico south through Guatemala, Honduras, and El Salvador into Nicaragua.

These include humid evergreen montane forest and cloudforest as well as drier deciduous, oak, pine, and pine-oak woodlands.

[8][9][10][11] The spot-crowned woodcreeper is mostly a year-round resident throughout its range, though some individuals move to lower elevations after the breeding season.

[8] The spot-crowned woodcreeper's diet is almost entirely arthropods; beetles and their egg cases appear to be a major component.

It nests in a cavity in a tree or stump, either natural or excavated by a woodpecker (Picidae} or barbet (Capitonidae), and usually within about 9 m (30 ft) of the ground.

[8] The IUCN follows HBW taxonomy and so it separately assessed the "northern" and "southern" spot-crowned woodcreepers.
