记述了产自云南中三叠世的裂齿鱼类3个新属种——邓氏富源裂齿鱼(Fuyuanperleidus dengi gen.et sp.nov.)、苏氏罗平裂齿鱼(Luopingperleidus sui gen.et sp.nov.)和小齿滇东裂齿鱼(Diandongperleidus denticulatus gen.et sp.nov.).邓氏富源裂齿鱼区别于其它裂齿鱼的特征,包括上颌骨形状、上下颌牙齿大小及形状、头骨纹饰、上颌骨与第一眶下骨愈合、高鳞片.苏氏罗平裂齿鱼区别于其它裂齿鱼的特征,包括三角形的鳃条骨、腹鳍前有4列水平方向的高鳞片、3个臀鳞.小齿滇东裂齿鱼区别于其它裂齿鱼的特征,包括胸鳍、腹鳍、背鳍和臀鳍前面鳍条的前缘具有小锯齿,鳞片后缘具有许多小锯齿.裂齿鱼类的新发现不仅丰富了中国华南裂齿鱼类的多样性,而且提供了裂齿鱼类在三叠纪全球辐射的新信息.

Three new genera and species of perladid fishes from the Middle Triassic scrata of Yunnan Province, i.e., Fuyuanperleidus dengi gen. et sp. nov.. Luopingperleidus sui gen. et sp. nov.,and Durndongperleidus denticulatus gen.et sp. nov.. are described in this paper. Fuyuanperleidus dengi is distinguishable from other perleidids by the shape of the maxilla, the big teeth, the ornamentation of the skull bones, maxillafused with the first infraorbital and the deepened flank scales. Luopingperleidus sui is distinguishable from other perleidids by the following features: the triangular main branchiostegal rays. four horizontal rows of deepened flank scales anterior to the pelvic fin, and three anal scales. Ihandongperleidus denticulatus is distinguishable fiom other perleidids by the following features:the antenor border of some antenor fin rays of both the paired fins and the dorsal and anal fins bearing dentictes, and posterior strongly serrated scales. The new discovenes not only add to the diversity of perleidid fishes in South China. but also shed ncw light on the ra diation of Triassic perleidid fishes in the world.
