Subspecies
Aulacorhynchus sulcatus (Sibley and Monroe 1990, 1993) was split into Groove-billed Toucanet (Aulacorhynchus sulcatus) and Aulacorhynchus calorhynchus by Stotz et al. (1996) but this treatment has not been adopted, following SACC (2005).

Forms a superspecies with Chestnut-tipped Toucanet (Aulacorhynchus derbianus). Rather closely related also to Emerald Toucanet (Aulacorhynchus prasinus), with which subspecies calorhynchus overlaps somewhat. Subspecies calorhynchus sometimes considered a separate species, but resembles other subspecies vocally and intergrades with nominate.

The following 3 subspecies are recognised:

calorhynchus Gould, 1874 - North-eastern Colombia (Santa Marta and Perij� Mts) eastern into western Venezuela (east to south-western Lara). Considered by some authors to be a distinct species, Yellow-billed Toucanet (Aulacorhynchus calorhynchus).
sulcatus (Swainson, 1820) - Northern Venezuela (Falc�n east to Miranda).
erythrognathus Gould, 1874 - North-eastern Venezuelan mountains.
