PODAGER WAGLER, 1832

Type species

Podager nacunda (Viellot, 1817) .

Definition

The clade containing P. nacunda and all species that share a more recent common ancestor with P. nacunda than with Chordeiles acutipennis , Chordeiles gundlachii , Chordeiles minor , Chordeiles rupestris , Chordeiles texensis , or any species in the genera Antrostomus , Caprimulgus , Eurostopodus , Gactornis , Hydropsalis , Lyncornis , Macrodipteryx , Nyctidromus , Nyctiphrynus , Nyctiprogne , Phalaenoptilus , Siphonorhis , or Veles .

Included species

Podager nacunda (Viellot, 1817) and Podager pusillus (Gould, 1861) .

Comments

Genetic evidence strongly demonstrates that Chordeiles pusillus (Gould, 1861) is the sister taxon to Podager nacunda (Viellot, 1817) , and should not remain in Chordeiles ( Fig. 4 ). Sequence divergence between P. nacunda and P. pusillus is quite high in the mitochondrial markers (12.0–13.5%). In the two nuclear markers, the sequence divergence is lower between P. pusillus and P. nacunda (1.1% in RAG- 1 and 3.7% in ACO1 I9) than between P. pusillus and C. acutipennis (1.6% in RAG- 1 and 4.8% in ACO1 I9), as well as P. pusillus and C. minor (2.4% in RAG- 1 and 4.7% in ACO1 I9). Han et al. (2010) moved P. nacunda into Chordeiles , but on our evidence we suggest the opposite modification, to place Chordeiles pusillus within Podager .
