| 摘 要： | 记述了产自广西南宁盆地渐新世早—中期的鲤科鲤亚科一新属种——伍氏南宁鲤(+Nanningocyprinus wui gen.et sp.nov).化石材料包括一些咽喉骨和咽齿.这些咽喉骨和咽齿的以下特征组合明显不同于其他鲤科鱼类:齿式-3·2·1,主行第一枚咽齿大小是第二枚的3～4倍,第二枚咽齿及第二行第一枚咽齿咀嚼面上各仅有一条沟纹,咽骨前角很发育.该属种的发现进一步证明鲤亚科是鲤科中较早的分支,中国南方很有可能是鲤亚科的起源和分化中心.

| Abstract: | Here we describe +Nanningocyprinus wui gen.et sp.nov,a fossil Cyprinus-like fish from the Early-Middle Oligocene deposits of Langdong,Nanning Basin,Guangxi Province,South China.+Nanningocyprinus wui is represented by a number of pharyngeal bones and teeth.It differs from all other cyprinid fishes in the following character combination:tooth formula -3·2· 1,crushing molar-like A 1 much larger than A2,only one groove on the grinding surface of A2 and B1 respectively,and the anterior angle of the pharyngeal bone triangular and prominent.The new-found Cyprinus-like fish,along with the previously known Late Eocene +Eoprocypris maomingensis (Procypris-like) and Oligocene ++Huashancyprinus robustispinus (Cyprinus-like) from South China,further indicates an early branching and diversification of the Cyprininae (Cyprinidae) in this area. |
