Aquila megaloptera Meyen, 1834a: 64, pl. 7.

Now: Phalcoboenus megalopterus (Meyen, 1834a) . See Hellmayr & Conover (1949: 278), Amadon (1964).

Holotype: ZMB 426 (Lichtenstein 1832, Nr. 52 as an unidentified form), skin, juv., collected by Meyen in “ Februar ” [= 17–19 Feb 1831; see below] in “ Chile ” [= western slopes of Volcán Maipo, Chile; see below].

Type locality. “ Chile ” according to Meyen (1834a: 65), who specified (p. 65): “ Er lebt in den höchsten Regionen der Cordilleren, stets in der Nähe des ewigen Schnee’s ” (“It lives in the highest regions of the cordillera, always near permanent snow”). The holotype was collected in February (Lichtenstein 1832, Meyen 1834a), when the Prinzess Louise was anchored at Valparaíso . This agrees with the fact that Meyen (1834b: 322–360) visited suitable habitat only during his trip to Volcán Maipo on 17–19 February 1831. We thus ascertain the type locality as western slopes of Volcán Maipo, Metropolitan Region, Chile [ca. 34.2°S, 69.9°W].
