Present species and H. longirostris occasionally separated in genus Anthoscenus on basis of squarish tail, rounded rectrices and details of bill morphology; the distinguishing features, however, vary in a continuum between these species and H. furcifer, with H. squamosus occupying intermediate position, and treatment of all four as congeners now generally accepted. Intergradation between race leocadiae and nominate apparently occurs in El Salvador. Proposed race surdus of W Mexico now usually considered a synonym of leocadiae. Three subspecies recognized.

Subspecies and Distribution
  • H. c. pinicola (Gould, 1853) – W Mexico (Sonora S to Jalisco).
  • H. c. leocadiae (Bourcier & Mulsant, 1852) – SW & S Mexico (Michoacán to Chiapas) and Guatemala.
  • H. c. constantii (DeLattre, 1843) – El Salvador S on Pacific slope to S Costa Rica.
