HYDROPSALIS DECUSSATUS (TSCHUDI, 1844)  

Definition

Previously Caprimulgus longirostris decussatus   . It is elevated to full species status. Its phylogenetic position within Hydropsalis   is not completely resolved in this study. It is part of a four-way polytomy that includes the following clades: (1) H. decussatus   ; (2) H. lyra   and H. segmentata   ; (3) H. parvulus   and H. heterurus   ; and (4) H. longirostris   , H. roraimae   , H. ruficervix   , H. anomalus   , H. candicans   , H. maculicaudus   , H. forcipata   , H. albicauda   , H. cayennensis   , H. climacocerca   , and H. torquata   .

Diagnosis

Small, cryptically coloured nightjar with a slender long bill. It is morphologically similar to H. l. atripunctatus in plumage and body shape, but much smaller in size. Territorial calls are also different ( Cleere, 2010).

Comments

Genetic evidence strongly supports H. decussatus   being an independent diagnosable species ( Fig. 7 View Figure 7 ). Although formerly a subspecies of H. (Caprimulgus) longirostris   , the phylogenetic results show that it is distant from H. longirostris   , despite some morphological similarities.
