摘要
摘要 对Sabanejewia larvata和S. aurata进行的颅骨学分析没有发现它们之间在头骨和颅骨的总体形态上存在根本性差异。与之前研究过的 Sabanejewia caspia、S. kubanica、S. caucasica 和 S. aralensis 相比,所有被研究的物种在某些颅骨学指标上都具有物种特异性。Sabanejewia larvata 和 S. caspia 最为相似,其特点是头骨在乙状体区域最低,前胸最宽,齿状体的上升突向前移,蝶窦最窄。这些结果证实了 Andrzewia 亚属的有效性。同时,观察到的 S. aurata 和 S. aralensis 的颅骨分化也证明了咸海盆地金鳅的独立物种地位。不过,还需要进一步的遗传学和形态学研究。
Craniological Features of Sabanejewia larvata (Cobitidae) and its Divergence from S. aurata and Other Congeneric Species
Abstract
The conducted craniological analysis of Sabanejewia larvata and S. aurata did not reveal fundamental differences in the general morphology of the skull and skull bones between them. Comparison with previously studied Sabanejewia caspia, S. kubanica, S. caucasica, and S. aralensis showed that all investigated species have species-specific values for some craniological indices. Sabanejewia larvata and S. caspia are most similar and are characterized by the lowest skull in the ethmoid region, the widest praeoperculum, the ascending process of the dentary displaced anteriorly, and the narrowest cleithrum. The obtained results confirm the validity of the subgenus Andrzewia. At the same time, the observed craniological divergence of S. aurata and S. aralensis testifies in favor of an independent species status of the golden loach from the Aral Sea basin. However, further genetic and morphological studies are needed.
期刊介绍:
Journal of Ichthyology is an international peer-reviewed journal published in collaboration with the Russian Academy of Sciences. It covers original studies in fish taxonomy, evolution, molecular biology, morphology, species diversity, zoological geography, genetics, physiology, ecology, behavior, reproduction, embryology, invasions, and protection. Some problems of applied ichthyology are also covered. The journal welcomes manuscripts from all countries in the English or Russian language.
