The spotted antbird (Hylophylax naevioides) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Colombia, Costa Rica, Ecuador, Honduras, Nicaragua, and Panama. The spotted antbird is 10 to 12 cm (3.9 to 4.7 in) long and weighs 15 to 19.5 g (0.53 to 0.69 oz). The two subspecies have essentially the same plumage. Adult males have a gray forehead and a grayish brown to olive-brown crown and nape. Their back is chestnut with a white and chestnut patch between their scapulars; the white is usually not visible. Their uppertail coverts are dull cinnamon. Their wings are black with cinnamon-rufous tips on the coverts. Their tail is grayish brown with cinnamon tips on most of the feathers (pale brown to white on the outermost) and a black band above the tips. Their lores and ear coverts are gray and their cheeks and throat are black. Their underparts are mostly white with a "necklace" of heavy black spots across the breast. Their sides are gray, their flanks brownish buff, and their undertail coverts pale brownish buff. Adult females have a dull brown crown and nape. Their back is the same chestnut as the male's and also has a hidden white and chestnut interscapular patch. Their wings and tail are like the male's. The sides of their head are blackish slate with pale cinnamon-brown lines. Their throat is white to buff. Their underparts are mostly white with irregular olive or dull gray spots on the breast. Their sides and flanks are olive to olive-buff. Juveniles are very similar to adults; males have grayish feathers on their chest and vent area and females have rusty white feathers there.
