Summary

A total of 51 new species of birds were described in the ten year period from 1956 to the end of 1965. Among these, 35 can be considered good species. They can be arranged in four groups:

Aa New species in new genera (2): 11, 49

Ab New species that are not clearly members of a super-species (13): 3, 9, 10, 15, 17, 21, 22, 27, 31, 35, 38, 43, 46

Ac Rather distinct allospecies (member of superspecies) (10): 1, 4, 5, 7, 20, 28, 40, 41, 47, 50

Ad Allospecies which some authors would consider merely subspecies (10): 2, 6, 14, ?18, 19, 26, 29, 36, 37, 39

In addition 16 other binomina were proposed, which — at this time — cannot be assigned the status of valid full species. These also fall into four categories:

Ba Species inquirendae (4): 12, 23, 30, 42

Bb Subspecies (7): 8, 13, 16, 32, 33, 34, 48

Bc Hybrid populations (1): 25

Bd Synonyms (4): 24, 44, 45, 51

It speaks rather highly of the current standards of description in ornithology that so few of the names turned out to be synonyms, although presumably some of the four Species inquirendae will have to be added to this category.

35 valid new species in a ten year period indicates that the number of undescribed new species of birds is by no means nearly exhausted, contrary to my earlier predictions. Even if the ten forms of category Ad were all reduced to subspecies rank, it would still leave 25 new species (2.5 per year, 1956–1965), a rate as high as that of the preceding fourteen year period (J. Orn., 98:22–35). I know of an additional 17 names published in the five years since 1965. South America, in particular, seems inexhaustible and has produced almost as many novelties (16) as the rest of the entire world (19). Indeed, it seems probable that, in the future, it will produce more novelties than all other continents and island regions together.

Zusammenfassung

Von 1956 bis Ende 1965 wurden insgesamt 51 Arten neu beschrieben, wovon 35 als gute Spezies betrachtet werden können. Sie lassen sich wie folgt gruppieren:

Aa Neue Spezies in neuen Genera: 11, 49

Ab Neue Spezies, die nicht offensichtlich Glieder einer Superspezies darstellen: 3, 9, 10, 15, 17, 21, 22, 27, 31, 35, 38, 43, 46

Ac Ziemlich gut unterschiedene Allospezies (Glieder einer Superspezies): 1, 4, 5, 7, 20, 28, 40, 41, 47, 50

Ad Allospezies, die einige Autoren als Subspezies betrachten: 2, 6, 14, 18?, 19, 26, 29, 36, 37, 39.

Hierzu kommen 16 weitere Vorschläge, die jedoch zur Zeit nicht den Status guter Arten zuerkannt erhalten können. Von ihnen sind nur 4, nämlich 24, 44, 45, 51 einwandfrei als Synonyme zu werten.

Die Zahl von 35 guten neuen Arten innerhalb einer Periode von 10 Jahren deutet an, daß im Gegensatz zu meiner früheren Voraussage die Zahl der noch nicht beschriebenen Vogelarten keineswegs nahezu erschöpft ist. Selbst nach Abzug der Formen von Kategorie Ad würden noch 25 neue Arten (2, 5 pro Jahr) bleiben, eine Rate, die der innerhalb der vorhergehenden 14 Jahre entspricht. Seit 1965 sind meines Wissens weitere 17 Namen publiziert worden. Südamerika erscheint im besonderen unerschöpflich und hat fast so viele Neuheiten (16) ergeben wie die gesamte übrige Welt (19). Möglicherweise werden in Zukunft hier mehr neue Arten entdeckt als in allen anderen Kontinenten und Inselregionen zusammen.
