Proposal (554) to South American Classification Committee
Change linear sequence in Coeligena
Effect on SACC: This proposal would rearrange the species sequence in Coeligena to reflect new phylogenetic
data.
Background & new information:
Our current sequence is:
Coeligena coeligena
Bronzy Inca
Coeligena wilsoni Brown Inca
Coeligena prunellei Black Inca
Coeligena torquata Collared Inca
Coeligena phalerata White-tailed
Starfrontlet
Coeligena orina Dusky Starfrontlet
Coeligena bonapartei Golden-bellied
Starfrontlet
Coeligena helianthea Blue-throated
Starfrontlet
Coeligena lutetiae Buff-winged Starfrontlet
Coeligena violifer Violet-throated
Starfrontlet
Coeligena iris Rainbow Starfrontlet
Our current footnote explains the situation:
53d. Coeligena lutetiae and C. violifer
were considered to form a superspecies by Parker et al. (1985); Schuchmann
(1999) also proposed that C. bonapartei and C. helianthea should
also be included in this superspecies. The latter two species may interbreed to
an uncertain extent (Fjeldså & Krabbe 1990). Parra et al. (2009) found that C. lutetiae and C.
violifer were not sister species and that the former is the sister taxon to
a group related as follows: C. iris +
(C. phalerata + ((C. orina + (((C. lutetiae +((((C.
helianthea + C. bonapartei)))))). SACC proposal
needed to change linear sequence.
Here is a summary tree from Parra et al. (2009):
To convert this well-supported phylogeny to a linear
sequence using standard conventions, the sequence looks like this, with changes
highlighted:
Coeligena coeligena
Bronzy Inca
Coeligena wilsoni Brown Inca
Coeligena prunellei Black Inca
Coeligena torquata Collared Inca
Coeligena violifer Violet-throated
Starfrontlet
Coeligena iris Rainbow
Starfrontlet
Coeligena phalerata White-tailed
Starfrontlet
Coeligena orina Dusky Starfrontlet
Coeligena lutetiae Buff-winged
Starfrontlet
Coeligena bonapartei Golden-bellied
Starfrontlet
Coeligena helianthea Blue-throated
Starfrontlet
Recommendation: This is basically a minor bookkeeping item to make sure our
linear sequences correspond to the latest phylogenetic data. I recommend a YES on this.

Comments from Nores: “YES. This
is a good example of how to convert a phylogeny to a linear sequence using standard
conventions.”
