Medium-sized Formicariidæ (length about 130-165 mm .) resembling Gymnocichla but loral and suborbital regions feathered (only the postocular and rictal regions naked), tail relatively shorter (two- thirds to three-fourths, instead of four-fifths, as long as wing), the adult males not black (or else without white tips to wing-coverts).
Bill shorter than head, rather slender to moderately stout, its width at frontal antiæ equal to or slightly greater than its depth at same point and equal to nearly if not quite half the distance from
nostril to tip of maxilla; culmen distinctly (sometimes rather sharply)
