The adult male type described in 1932 had a white stripe down the crown and nape, bordered by broad black stripes. Its mantle was gray with dark shaft streaks, and its rufous-brown tail had pale buff tips.
A 2007 vocal study recorded the male song of the population then called H. striata implicata. A recording from Borba, Brazil, begins with a long falling note followed by short, abrupt notes that accelerate.
