I forgot, Bolborhynchus is paraphyletic with Nannopsittaca albeit (or though?) only one Bolborhynchus species is sampled. It's maybe too soon to merge Nann. into Bolb. Do you know if there is a study in which all species of Bolborhynchus are included?

The only other 'Bolborhynchus' that has sequences in GenBank is 'B.' aymara, which is in Psilopsiagon in recent classifications.

There are barcodes for all the seven spp of the group in BOLD, however (3 Bolborhynchus species, 2 Nannopsittaca species, 2 Psilopsiagon species--albeit the sequences of B. lineola and N. dachilleae are not (yet) publicly available). Identification trees suggest B. orbygnesius and B. ferrugineifrons are close to each other (uncorrected distance < 1%), but not particularly close to B. lineola (which is the type), nor to Nannopsittaca. In fact, these two seem closer to Psilopsiagon.

I've attached an ID tree (produced by submitting a panychlora seq to the BOLD ID engine), and a rapidly bootstrapped ML tree (based on the publicly available seqs, thus no lineola and no dachilleae).

Merci Laurent vous êtes un dieu

So, only B. lineola is paraphyletic with Nannopsittaca. Anyway, my suggestion don't (or doesn't, I have a doubt) change but the remaining Bolb. is merging into Psilopsiagon because no name is available for ferrugeneifrons and orbygnesius.

However, it's not stupid to use one genus for the entire clade.

orbygnesius was described by Bonaparte as Myiopsittica orbygnesia in 1854 but Ridgway thought it belonged in Amoropsittica . No. 50 part VII 1916. Aves de Bolivia 1985 says Bolborhynchus aymara= Amoropsittica a(ymara).

Ridgway 1912 in the same publication with Nannopsittaca Ridgway also created Grammopsittica for P. lineola.

...As well as Psilopsiagon for Psittacus aurifrons 'Wagler' = Lesson 1830.

There was some confusion, which originated in how Bonaparte introduced Bolborhynchus. In 1857, Bonaparte published two notes on parrots in the Comptes-rendus of the Académie des Sciences:
- Bonaparte CL. 1857. Remarques du Prince Bonaparte à propos des observations de M. Emile Blanchard sur les caractères ostéologiques chez les oiseaux de la famille des Psittacides. C.-R. Hebd. Séan. Acad. Sci. Paris, 44:534-539.
- Bonaparte CL. 1857. Tableau des genres de perroquets disposés en séries parallèles. C.-R. Séan. Hebd. Acad. Sci., Paris, 44:595-597.
Bonaparte first used Bolborhynchus in the second note, [here], merely listing it in a table, without any description or included species. A few weeks later, however, he published a 'reprint' that combined these two notes, with an amended text; there, he used Bolborhynchus for two species, in the part of the text corresponding to the original first note ('reprint' [here]; original [here] for comparison: the same two species were originally placed in Myiopsitta).

Bolborhynchus was nude in the journal, but is available from the 'reprint', originally included species Myiopsitta tigrina Souancé (now Bolborhynchus lineola tigrinus) and M. catharina Bonaparte (a synonym of lineola Cassin), one of which must be the type. (Which one matters little, as they are near-synonyms.) Subsequent workers initially did not notice the amendments in the reprint, however; they just checked the original journal version, discarded the name as nude in this work, and accepted it as available from the slightly later Iconographie des Perroquets [here], originally included species aymara, orbignesia and aurifrons, the first of which was treated as the type.

In 1912, Ridgway placed aymara in Bolborhynchus, because he believed it to be the type of the genus; consistent with this, he created a new genus for lineola, which he intended to separate (together with andicola Finsch, which is indeed a synonym of orbygnesia) from aymara. Three years later, the source of the name was corrected by Richmond [here], who moved Bolborhynchus onto lineola (designating M. catharina Bp as its type, and making Ridgway's Grammopsittaca a junior synonym); Richmond then created Amoropsittaca for aymara which, having 'lost' Bolborhynchus, was left without a genus name. In 1916, Ridgway was merely accepting Richmond's nomenclatural correction.
