Pseudocolaptes (p. 196).
- cc. Nostril oval or roundish, not distinctly operculate. (Automoleæ.)
- d. Basal phalanx of middle toe wholly united to both outer and inner toes.
- e. Bill much longer, the exposed culmen longer than tarsus, its length from nostril equal to two and a half times its depth at loral antiæ.
- d. Basal phalanx of middle toe wholly united to both outer and inner toes.
- cc. Nostril oval or roundish, not distinctly operculate. (Automoleæ.)
Hyloctistes (p. 199).
- ee. Bill much shorter, the exposed culmen shorter than tarsus, its length from nostril equal to but little more than twice its depth at loral antiæ.
- f. Bill relatively broader basally and more compressed terminally, the tip of maxilla abruptly and strongly uncinate; upper parts conspicuously streaked.
- ee. Bill much shorter, the exposed culmen shorter than tarsus, its length from nostril equal to but little more than twice its depth at loral antiæ.
Ancistrops (extralimital).[1]
- ff. Bill relatively narrower basally and less compressed terminally, the tip of maxilla not abruptly nor strongly, if at all, uncinate; upper parts not streaked.
- g. Bill excessively compressed, its width at loral antiæ equal to only about two-thirds its depth at same point and less than one-third the distance from nostril to tip of maxilla; claw of hallux very large, as long as the digit.
- ff. Bill relatively narrower basally and less compressed terminally, the tip of maxilla not abruptly nor strongly, if at all, uncinate; upper parts not streaked.
Anabazenops (extralimital).[2]
- gg. Bill only moderately compressed, its width at loral antiæ equal to more than two-thirds its depth at same point and more than one-third the distance from nostril to tip of maxilla; claw of hallux smaller, decidedly shorter than the digit.
Philydor (p. 201).
- dd. Basal phalanx of middle toe not wholly united to lateral toes.
- e. Bill relatively smaller, more slender, more compressed, its width at loral antiæ much less than its depth at same point, not distinctly if at all uncinate; shafts of rectrices softer at tip.
- f. Bill smaller, the culmen (from base) shorter than tarsus; anterior toes more extensively united basally.
- g. Bill smaller and more slender, more decurved terminally, with gonys not ascending terminally.
- f. Bill smaller, the culmen (from base) shorter than tarsus; anterior toes more extensively united basally.
- e. Bill relatively smaller, more slender, more compressed, its width at loral antiæ much less than its depth at same point, not distinctly if at all uncinate; shafts of rectrices softer at tip.
- dd. Basal phalanx of middle toe not wholly united to lateral toes.
Heliobletus (extralimital).[3]
- gg. Bill larger and stronger, less deciurved terminally (except at extreme tip), with gonys strongly ascending terminally.
Xenicopsis (p. 205).
- ff. Bill larger, the culmen (from base) longer than tarsus; anterior toes less extensively limited basally.
Automolus (p. 211).
- ee. Bill larger and stouter, less compressed, its width at loral antiæ nearly equal to its depth at same point, distinctly uncinate; shafts of rectrices more rigid at tip.
