Aquila pezopora Meyen, 1834a: 62, pl. 6.
Now: Milvago chimango chimango (Vieillot, 1816) . See Hellmayr & Conover (1949: 266).
Syntype: ZMB 434 (Lichtenstein 1832, Nr. 45 or 46 sub “ Falco degener ”), skin, juv., collected by Meyen in “ Maerz ” [= 20–23 Feb 1831; see below] in “ Chile ” [= Colina, Chile; see below].
Syntype (lost): ZMB 435, collected by Eduard Poeppig on an unknown date [= 1827–1829] in Chile.
Syntype: ZMB 437 (Lichtenstein 1832, Nr. 45 or 46 sub “ Falco degener ”), skin, ♀, collected by Meyen in “ Maerz ” [= 20–23 Feb1831; see below] in “ Chile ” [= Colina, Chile; see below].
Type locality. Meyen (1834a: 64) wrote: “Lebt in grosser Anzahl auf den Feldern der Ebene vom Mapocho, besonders in der Nähe von Santiago . ” (“Lives in great numbers on the fields of the Mapocho plain, especially near Santiago.”) Lichtenstein (1832) stated that Meyen’s syntypes were collected in March, but Meyen (1834b: 365) left Santiago on 24 February and spent the remaining days before his ship’s departure in Valparaíso ; hence he could not have collected any birds at Santiago in March. The only period during which Meyen explored the vicinity of Santiago was 20–23 February, when he went to Colina (Meyen 1834b: 360–365). During this trip he observed and collected Milvago chimango (see Meyen 1834b: 361). Poeppig collected one syntypical specimen at an unknown locality in Chile. The type locality of Aquila pezopora is thus Chile (including Colina, Metropolitan Region, 33.20°S, 70.68°W).
Remarks. Meyen (1834a) did not specify the type series, but Lichtenstein (1832) listed two specimens collected by Meyen which are surviving types. ZMB registers show that Poeppig's specimen was available to Meyen during his ZMB visit, although it is now lost. All three specimens constitute the type series.
