https://www.biodiversitylibrary.org/page/17136778 ; Trochilus quadricolor Vieillot 1822; but this is not correct: Gray was dealing with Cyanomyia Bonaparte, with Uranomitra merely cited as a (potentially subjective) synonym, and not concerned by the designation. Besides, Reichenbach did not actually include Trochilus quadricolor Vieillot 1822, but “T. quadricolor Vieillot 1818”, which is quite problematic as there is also a Trochilus quadricolor Vieillot 1817 (Vieillot LP. 1817.

The separate version was presented by Bonaparte to the Académie (and said to be just published) on 24 Apr 1854 (https://www.biodiversitylibrary.org/page/1215778 ); it was noticed as published on 6 May 1854 in Bibliogr. France (https://books.google.be/books?id=c9dLAAAAcAAJ&pg=PA290 ); this is before the journal version appeared; this issue of the journal includes reports on meetings of the Académie up to 29 May, hence can’t have been published before this date.

I see no problem with Uranomitra.
I agree with the type fixation for Cyanomyia.
If "Leucolia Mulsant & E. Verreaux, 1866, [is here] interpreted as an additional synonym of Leucippus Bonaparte, 1850, with the same type species, Trochilus fallax Bourcier, 1843", this is a type designation that
makes fallax Bourcier 1843 the type. (So the authors have just destroyed Leucolia once and for all -- despite it was, and could have remained, in use -- which allows them to propose their own name for the group. I'm curious to know the justification.)
I assume that the authors did not really intend to "propose replacement names for both Uranomitra and Leucolia" (which would merely create invalid junior objective synonyms of the replaced names), but to describe the groups known in the recent literature as Uranomitra and Leucolia, which they regarded as nameless due to a reinterpretion of these two names, as brand new genera.
Edit -- I just changed my mind about the bibliographic source for Bonaparte's name. (Bonaparte is generally a bibliographic nightmare. Here, the "separate" version of the work was in fact demonstrably published by him before the journal version. The "separate" was not identical to the journal version -- the typesetting and page layout in the two versions are completely different.)
