'Bogotá' Type Specimens of the Hummingbird Genus Adelomyia
Thomas M. Donegan & Jorge Enrique Avendaño 195 Bull. B.O.C. 2015 135(3) ‘Bogotá’ type specimens of the hummingbird genus Adelomyia, with diagnosis of an overlooked subspecies from the East Andes of Colombia by Thomas M. Donegan & Jorge Enrique Avendaño Received 25 September 2014 Summary.—Molecular work has revealed that Speckled Hummingbirds Adelomyia melanogenys in the East Andes of dpto. Santander, Colombia, represent a distinct lineage not previously recognised taxonomically. Most specimens from this region differ from others taken in the East Andes by their more extensively rufous and speckled posterior underparts. Sound-recordings and biometrics showed broad overlap for all variables in both populations. Statistically significant but non- diagnosable differences exist in the number of notes in trills of songs, speed of calls and bill length. The type of Adelomyia melanogenys (Fraser 1840) is a ‘Bogotá’ specimen similar to birds from dpto. Cundinamarca, Colombia. Trochilus sabinae Bourcier & Mulsant, 1846, is also based on a ‘Colombia’ specimen. A possible type was identified that resembles the Santander population in its underparts.Adelomyia simplex Boucard, 1893, is based on a leucistic ‘Bogotá’ specimen more consistent with the Cundinamarca population than others. If the Santander population is recognised taxonomically, it is suggested to clarify the type locality for sabinae as the west slope of the East Andes in Santander or Boyacá, but molecular work is needed to confirm this. A. m. inornata in the southern Andes has a faster call and distinctive plumage, and perhaps merits species rank. The genus Adelomyia is monospecific, comprising the polytypic Speckled Hummingbird A. melanogenys, a widespread Andean hummingbird.
