We report here a karyotypic study of 6 individuals of Hylobates concolor leucogenys, 2H, concolor siki, 3H, concolor gabriellae, 1 hybrid H, concolor leucogenys x H. concolor ski, 3 hybrid H. concolor gabriellae x H. concolor siki and 2 hybrid H. concolor hainanus x H. concolor leucogenys. Difficulties raised by the morphological identification of subspecies are discussed, and a new morphological characteristic for recognising female H. concolor gabriellae is described. Each of the 4 subspecies appears to be distinguishable on the basis of its karyotype: H. concolor leucogenys differs from H. concolor siki by a reciprocal translocation, from H. concolor hainanus by a pericentric inversion and from H. concolor gabriellae by the presence of both of these two rearrangements. However, these data do not allows us to identify a phylogenetic relationship between the subspecies because, with respect to the karyotypes, none occupies an ancestral position in comparison with the others.
我们在此报告对6只白颊长臂猿指名亚种（白颊长臂猿海南亚种，2只；白颊长臂猿西氏亚种，3只；白颊长臂猿加氏亚种，1只）、1只白颊长臂猿指名亚种与白颊长臂猿西氏亚种的杂交个体、3只白颊长臂猿加氏亚种与白颊长臂猿西氏亚种的杂交个体以及2只白颊长臂猿海南亚种与白颊长臂猿指名亚种的杂交个体的核型研究。讨论了亚种形态鉴定所带来的困难，并描述了一种识别雌性白颊长臂猿加氏亚种的新形态特征。4个亚种中的每一个似乎都可根据其核型加以区分：白颊长臂猿指名亚种与白颊长臂猿西氏亚种的区别在于相互易位，与白颊长臂猿海南亚种的区别在于臂间倒位，与白颊长臂猿加氏亚种的区别在于同时存在这两种重排。然而，这些数据无法让我们确定亚种之间的系统发育关系，因为就核型而言，与其他亚种相比，没有一个亚种处于祖先位置。
