分类信息
The chestnut-tipped toucanet is monotypic. However, what is now the tepui toucanet (A. whitelianus) and it were for a time considered conspecific. They were separated by major taxonomic systems beginning in 2011. The chestnut-tipped and groove-billed toucanets (A. sulcatus) form a superspecies.
