HYDROPSALIS RORAIMAE (CHAPMAN, 1929)  

Definition

Previously Caprimulgus longirostris roraimae   . It is elevated to full species status. It is the sister species

of H. ruficervix   . Together the two species form a clade that is sister to H. longirostris   .

Diagnosis

Large, very dark, long-billed nightjar with few markings in plumage. It is most similar to H. ruficervix   , but is both larger and darker.

There is genetic divergence in both ND2 and ACO1 I9, with 3.7% divergence in ND2 between H. roraimae   and H. ruficervix   and 5% divergence between the two and H. longirostris   .

Comments

Genetic evidence in this study supports elevating the two closely related subspecies of H. longirostris   , H. l. roraimae   and H. l. ruficervix   , to phylogenetic species status, as they are genetically divergent from the remaining taxa assigned to H. longirostris   (H. l. atripunctatus, H. l. bifasciatus, H. l. longirostris   , and H. l. patagonicus), as well as from one another ( Fig. 7 View Figure 7 ). This is in agreement with the suggestions of Cleere (2010), at least regarding H. l. roraimae   .
