UPPER MIOCENE BIRDS FROM LUFENG, YUNNAN

The discovery indicates the first record of fossil birds from South China. 3 Orders, 3 Families, 6 Genera, 6 Species including 2 new genera and 4 new species are described in the present paper. They are Anas sp.; Aythya, shihubas sp. nov.; Bambusicala sp.; Di-angallus mious gen. et sp. nov.; Phasinaus lufengia sp. nov.; Yunnanus gaoyuansis gen. et sp. nov.; and order family indet. The fossils were collected together with Ranwpithecus, Sivapithecus and other vertebrate animals by a field party of IVPP. in Upper Miocene in the Shihuba, Lufeng County, Yunnan Province during 1980-1984. This is the brief report of my paper "Upper Miocene birds from Lufeng, Yunnan, China". Family Anatidac Genus: Aythya, Boie Aythya shihubas sp. nov. Characters: The proximal end of left humerus similar to Aythya, but the difference with the other species as follows: (1) the head of humerus smaller, the capital crest bigger, there is a groove in attachment of latissimus dorsi posterioris; (2) the external tu-berosity of proximal end of humerus not clear, deltoid crest not expanded; (3) the liga-menital furrow deep, bicipital surface smaller. Family: Phasianidae Genus: Diangallus gen. nov. Diangallus mious sp. nov. Characters: The size similar to Gallus, tarsometatarsus wider, bone wall thick, cal-car long and curved, tubercle for tibialis antieus very large, trochleae for digits 3 arch. Genus: Phasinaus Linnaeus Phasinaus lufengia sp. nov Characters: Similar to Phasinaus, but the difference with the other species in the following: (1) tibiotarsus shrink, antero-posteriorly not flat; (2) inner condyle and outer condyle of tibiotarsus expanded; anterior intereondylar fossa deep and wide; (3) tarsometatarsus more slight than other species; (4) trochleae of distal end of tarsometa- tarsus slightly arched. Family: Incertae Sedis Genus: Yunnanus gen. nov. Tunnanus gatoyuansis sp. nov. Characters: Small passerine. (1) head of humerus large, capital groove deep, pne-matic formen only one, ligamental furrow not deep, deltoid crest thick; (2) the shaft of humerus more slightly, but proximal end and distal end expanded, oleeranal fossa large and deep, tricipital groove very developed, internal condyle developed; (3) eoraeoid more strong, sterno-coracoidal impression not clearly expanded; (4) head of femur very small, crista troehanteris not developed, impressiones obturatoriae clearly; (i) tibiotar-sus strong and long, but internal condyle and external condyle not expanded.
