Aulacorhynchus prasinus (Sibley and Monroe 1990, 1993) was split into Emerald Toucanet (Aulacorhynchus prasinus), Wagler's Toucanet (Aulacorhynchus wagleri), Blue-throated Toucanet (Aulacorhynchus caeruleogularis), Violet-throated Toucanet (Aulacorhynchus cognatus), Northern Andean Toucanet (Aulacorhynchus lautus), Greyish-throated Toucanet (Aulacorhynchus albivitta) and Black-throated Toucanet (Aulacorhynchus atrogularis) by Navarro et al. (2001), on the basis mainly of differences in bill pattern and throat colour, but this treatment is not followed by SACC (2005), or the BirdLife Taxonomic Working Group as it is considered premature.
