The Aegean Luciobarbus graecus, L. lydianus, and L. kottelati were described based on morphological characters. However, re-examination of fresh material from the three species revealed greater intraspecific variability in morphological character states, and wider overlaps in all postulated diagnostic traits than initially documented. Consequently, it is not possible to identify and distinguish these three species based solely on morphological characteristics. As they also share identical COI barcode sequences, these species are now considered conspecifics, and L. lydianus and L. kottelati are treated as junior synonyms of L. graecus. The distribution of L. graecus remains a biogeographical puzzle, and it cannot be excluded that this could be partly human-mediated. Population-level genomic studies, particularly those focusing on phylogeography and population genetics, may help clarify mechanisms underlying contemporary distribution of this species.
基于形态特征描述了爱琴海 Luciobarbus graecus、L. lydianus 和 L. kottelati 三个物种。然而，对来自这三个物种的新鲜材料的重新检查表明，形态特征的种内变异性更大，所有假定的诊断特征的重叠范围也比最初记录的更广泛。因此，仅基于形态特征不可能识别和区分这三个物种。由于它们还具有相同的 COI 条码序列，因此这些物种现在被认为是同种的，而 L. lydianus 和 L. kottelati 则被视为 L. graecus 的次异名。L. graecus 的分布仍然是一个生物地理学谜题，不能排除这可能部分是人为介导的。基于种群的基因组研究，特别是那些专注于系统地理学和种群遗传学的研究，可能有助于阐明该物种当代分布的机制。
