Abstract

This paper presents the results of a comparative study of eight osteological characters: the counts, dimension and regionalization of the vertebral column, the pattern of interdigitation of the dorsal- and anal-fin pterygiophores with the neural and haemal spines of the vertebrae, the distribution of the dorsal- and ventral-procurrent caudal-fin rays, the distribution of the principal caudal-fin rays, and the morphology of the caudal-fin skeleton of six species of the Capoeta damascina complex (Cypriniformes: Cyprinidae). Potential taxonomically valuable osteological characters are described and used to separate the six species of Capoeta studied. Formulae for the structure of the vertebral column, the dorsal- and anal-fin pterygiophores’ interdigitation with the neural and haemal spines of the vertebrae, the distribution of the dorsal and ventral procurrent caudal-fin rays, and the distribution of the principal caudal-fin rays are developed. These morphological descriptive parameters express a morphotype that may be linked with the cypriniform mode of swimming of the Capoeta species investigated. The morphological study of the vertebral column of six species of the Capoeta damascina complex enables the division of this bony structure into five or six morphologically distinct regions, depending on the species, and the drawing of characteristic vertebral profiles. This regionalization is more complicated than the classical division in abdominal and caudal parts only.

定义六种Capoeta damascina物种复合体（鲤形目：鲤科）的骨学特征

摘要

本文介绍了八个骨学特征的比较研究结果：椎骨的数量，尺寸和区域分布，背鳍和臀鳍翼状phor肉与椎体的神经和血棘的交叉指状模式，分布六种Capoeta damascina复合体（Cypriniformes：Cyprinidae）的背鳍和腹鳍近侧尾鳍射线，主要尾鳍射线的分布以及尾鳍骨架的形态。描述了潜在的生物分类学有价值的骨学特征，并用于分离六种卡波埃塔研究。脊柱结构，背鳍和臀鳍翼状ery与椎体的神经和血棘交指，背鳍和腹鳍近前尾鳍射线的分布以及主要的尾鳍分布鳍条被显影。这些形态学描述性参数表示可与游泳的cypriniform模式连接的形态型Capoeta调查物种。六种Capoeta damascina椎骨柱的形态学研究。复杂的结构可以将这种骨结构划分为五个或六个形态上不同的区域，具体取决于物种和特征性椎骨轮廓的绘制。这种区域划分比仅在腹部和尾部的经典划分更为复杂。
