中国鲳属鱼类一新种(鲈形目,鲳科)(英文)

A NEW SPECIES OF THE GENUS PAMPUS (PERCIFORMES,STROMATEIDAE) FROM CHINA

描述了分布于中国东南沿海的鲳科鲳属鱼类I新种，刘氏鲳Pampuliuorumsp．nov．。与鲳属其它已知种比较，刘氏鲳体为长椭圆形，个体大而强壮；背鳍具37～4l鳍条；臀鳍具36—40鳍条，前部鳍条延长超过尾柄；鳃耙退化，第1鳃弓上具8～12结节状鳃耙；脊椎骨38个；新鲜标本体为银灰色并带金黄色或铜蓝色金属光泽。

Pampus Iiuorum sp. nov. is described on the basis of 18 specimens collected from Fujian, Guangdong, Guangxi and Hainan, China. It is similar to P. punctatissimus and P. cinereus in overall body appearance and having gready extended anterior rays of anal fin. But this new species can be easily distinguished from P. punctamus by the shape of mouth （subtermJnal vs. terminal）, different number of total vertebrae （38 vs. 34）, different shape and number of gill rakers （8 - 12 vestigial and tubercular gill rakers vs. 10 - 13 long and slender gill rakers）. It differs from P. chreus in having higher count of total vertebrae （38 vs. 36）, shorter pectoral-fin length （31.5 % -41.5 % vs. 42. 0 % -47.2 % ） and shorter eye diameter （ 19.4 % - 25.0 % vs. 27.7 % - 30. 7 % ）. This new species usually has golden bronze coloration on dorsal surfaces of body in fresh scaleless specimens.
