Comments

Genetic evidence in this study supports a large clade that contains members of five genera: Caprimulgus   , Eleothreptus   , Hydropsalis   , Macropsalis   , and Uropsalis   ( Fig. 7 View Figure 7 ). The name Caprimulgus   cannot be used for any New World taxa, as the type species is Caprimulgus europaeus (Linnaeus, 1758)   , a member of the crown Old World radiation. The species in this clade, traditionally placed in Caprimulgus   , do not form a monophyletic assemblage, and cannot be placed in a single genus unless membership is extended to the other four New World genera. Therefore, in order to avoid creating additional new genera to maintain the monophyly of Hydropsalis   itself, we conclude that the simplest and preferable solution is to move the species of Eleothreptus   , Hydropsalis   , Macropsalis   , and Uropsalis   into a single genus, along with the previous members of Caprimulgus   . Hydropsalis   is the oldest available name. Unlike Han et al. (2010), we do not propose to move members of Lurocalis   , Nyctidromus   , and Nyctiprogne   into Hydropsalis   .
