SEPARACION DEL ORDEN CAPRIMULGIFORMES 57th Supplement: Auk 2016

[pp. 267–274] Phylogenomic analyses of nuclear
DNA sequences have shown that the ordinal limits and
linear sequence of families in the traditional order
Caprimulgiformes do not reflect their evolutionary relationships
(Hackett et al. 2008, Prum et al. 2015). Their
findings result in the following changes:
Change the heading Order CAPRIMULGIFORMES:
Goatsuckers, Oilbirds, and Allies to Order CAPRIMULGIFORMES:
Nightjars, and insert the following Notes
after this heading:
Notes.—Formerly included Steatornithidae, Nyctibiidae,
and extralimital families Podargidae and Aegothelidae, but
phylogenomic analyses of nuclear and mitochondrial DNA
sequences have shown that the traditional order Caprimulgiformes
is paraphyletic with respect to the Apodiformes
(Hackett et al. 2008, Jarvis et al. 2014, Prum et al.
2015) and that lineages in this order that are traditionally
ranked as families are as old or older than most currently
recognized orders (Mayr 2014, Prum et al. 2015).
Change the heading Family CAPRIMULGIDAE: Goatsuckers
to Family CAPRIMULGIDAE: Nightjars.
After the species account for Caprimulgus indicus,
insert the following heading and Notes:
Order STEATORNITHIFORMES: Oilbirds
Notes.—See Notes under Caprimulgiformes.
Move the heading Family STEATORNITHIDAE: Oilbirds,
and the genus and species accounts included under
this heading to a position following this newly inserted order.
After the species account for Steatornis caripensis, insert
the following heading and Notes:
Order NYCTIBIIFORMES: Potoos
Notes.—See Notes under Caprimulgiformes.
Move the heading Family NYCTIBIIDAE: Potoos, and
the genus and species accounts included under this
heading to a position following this newly inserted order
