Hirundo leucopygia Taczanowski, 1880

Taczanowski (1880: 192) based this species on four specimens collected by Jan Sztolcman (1854–1928) in September 1871 at Chepén, Peru [7.22°S, 79.45°W]. Three of these specimens were deposited in the MIZ in the 1880s ( Taczanowski 1889: 7), but none survive (Mlíkovský 2009; see also Sztolcman & Domaniewski 1927). The fate of the fourth syntype is unknown. Hirundo leucopygia Taczanowski, 1880 , is a junior primary homonym of Hirundo leucopyga Meyen, 1834 (see ICZN 1999, Art. 53.3.; see also ICZN 1999, Art. 58.15., according to which the endings – a and –ia are deemed identical). Philippi (1902: 23) correctly observed that Hirundo leucopygia Taczanowski, 1880 , is preoccupied by Hirundo leucopyga Meyen, 1834 , and replaced the former name with Hirundo stolzmanni . The Tumbes Swallow is currently known under the latter name.
