Amoropsittacini/ Touitini

We acknowledge the recent introduction of Touitini by Sangster et al. (2023) to encompass the genera Touit , Bolborhynchus , Psilopsiagon , and Nannopsittaca , and thereby replacing Amoropsittacini Brereton, 1963. As noted above, we similarly acknowledge concomitant preparation of a counterargument by Schodde et al. (submitted) to conserve the family-group name Amoropsittacidae Brereton, 1963. If accepted, the latter still allows retention of Touitini for recognition as a monotypic tribe i.e., containing only Touit . Until this is resolved, we use Touitini for Touit and Amoropsittacini for the other three genera for reasons we now outline.

There was a deep divergence that dates to 21.1 Mya (13.7–25.5) between Touit and the clade containing Bolborhynchus , Psilopsiagon , and Nannospsittaca, which in turn exhibits a basal divergence dating to 16.9 Mya (10.3–21; fig. 5). Based on these deep divergences, we advocate recognition of two tribes, one for Touit and one for Bolborhynchus , Psilopsiagon , and Nannopsittaca , this decision being driven largely by the molecular data.
