status

 

NYCTIDROMUS DERBYANUS   GOULD, 1838

Definition

Previously Nyctidromus albicollis derbyanus   . It is elevated to full species status and is the sister species of N. albicollis   .

Diagnosis

Noticeably larger than both N. albicollis   and N. merrilli   . Back, crown, outer primaries and secondaries are distinctly reddish in colour. Not as dark in colour as N. albicollis   .

Comments

Genetic evidence in this study is consistent with N. albicollis   being split into three phylogenetic species ( Fig. 6 View Figure 6 ). Members of the nominate subspecies remain as N. albicollis   , whereas N. a. derbyanus   is elevated to full phylospecies status under the name N. derbyanus   . Some individuals identified as N. a. albicollis   may also belong to this phylospecies, particularly south of the Amazon River (see details in Discussion). The remaining four subspecies, N. a. insularis, N. a. intercedens, N. a. merrilli   , and N. a. yucatanensis, can be united as a phylogenetic species: N. merrilli   (see below).
