The white-wedged piculet (Picumnus albosquamatus) is a species of bird in subfamily Picumninae of the woodpecker family Picidae.

Their chin and throat feathers are pale buffish white with black edges that give a scaly appearance.

Their underparts are mostly whitish with a pale buff wash; the breast has a scalloped appearance from black feather edges and the belly is plain or slightly streaked.

Their iris is brown, the orbital ring grayish, the bill black with a paler base on the mandible, and the legs gray to green-gray.

It is usually darker, with more contrast on the face, more of a scalloped pattern on the upperparts, and warm buff underparts with wider black edges on the feathers.

[5] The nominate subspecies of white-wedged piculet is found in north-central and eastern Bolivia, southwestern Brazil's Mato Grosso state, northern Paraguay, and northwestern Argentina.

P. a. guttifer is found in eastern and central Brazil from Pará and Maranhão south to Mato Grosso and São Paulo.
