Other common names: Whitely's Toucanet

Aulacorhamphus whitelianus

Salvin and Godman

, 1882,

Merume Mountains, Guyana


Until recently considered conspecific with A. derbianus but split, proposed on genetic grounds#R, supported by morphological evidence: differs by virtue of extensive red on upper mandible (3); lack of blue on nape (2); shorter dull rufous tail tips (1); smaller size (effect size for male wing –2.48, but n=6 for derbianus, n=9 for whitelianus; score 2). Sometimes misspelt whitleyanus. Three subspecies currently recognized.
