“i. Sancti-Thomae Insula”; error = Santo Tomás, Izabal, Guatemala.
Hitherto treated as conspecific with D. punctipectus and until recently also with D. certhia (which see). Race sheffleri considered a distinctive single-taxon “group” by some authors#R. Variation in both bill length and extent of pale base of lower mandible is clinal in nominate; this, combined with a typographical error, resulted in description of races nigrirostris (Costa Rica, Panama) and colombianus (W Colombia, NW Ecuador), both subsequently synonymized. Supposed variation leading to description of legtersi (Yucatán Peninsula) appears to reflect an artifact of type series. Three subspecies recognized.
