Abstract

The craniological analysis of Cobitis derzhavini from the Mingechaur Reservoir system and C. saniae from the Malyi Kyzylagach Bay drainage and the Alvady River in Azerbaijan did not reveal any fundamental differences in the general morphology of the neurocranium and cranial bones between these species, as well as from the previously studied C. taenia, C. melanoleuca and C. taurica. However, C. derzhavini showed high level of diversity from other Cobitis species in the proportions of some bones, at first, operculum. The results confirm that C. derzhavini is a separate species characterized by a predominance of opercular bone with weakly excised posterior margin, in contrast to opercular bone with deeply excised posterior margin observed in other craniologically studied species of Cobitis and Sabanejewia.

抽象

的craniological分析Cobitis derzhavini从Mingechaur水库系统和C. saniae从Malyi Kyzylagach湾排水和Alvady河阿塞拜疆没有透露在脑颅和这些物种之间的颅骨的一般形态的任何根本性的分歧，以及来自先前研究的taenia，C. melanoleuca和taurica。然而，最初，C。derzhavini在某些骨头的比例上表现出与其他Cobitis物种较高的多样性。结果证实C. derzhavini是一个独立的物种，其特征是具有以远位切除的后缘为主要的骨膜骨，而在其他经过颅骨学研究的科比炎和萨宾内氏菌种中观察到的是具有深位切除的后缘的骨性骨。
