The Volturno Spined Loach Cobitis zanandreai is thought to be restricted to only two places in Italy, the Fondi Lake (Latium) and the Volturno river basin (Campania). In this study we carried out a review of the available literature and surveyed 37 sites of potential occurrence. We discovered seven previously unknown populations of C. zanandreai in the Liri-Garigliano and the Pontine plain watersheds, significantly expanding the known limits of its distribution. We found the invasive C. bilineata only in the Amaseno River. Our results agree with records from the 19th and 20th centuries, highlighting the importance of historical data in understanding current species distribution. Our findings provided a substantial distribution update that allow to assess the species conservation status more objectively.

Volturno 刺泥鳅 Cobitis zanandreai (Teleostei: Cobitidae) 分布的新数据

Volturno Spined Loach Cobitis zanandreai被认为仅限于意大利的两个地方，丰迪湖（Latium）和沃尔图诺河流域（坎帕尼亚）。在这项研究中，我们对现有文献进行了回顾，并调查了 37 个可能发生的地点。我们在 Liri-Garigliano 和 Pontine 平原流域发现了七个以前未知的C. zanandreai种群，显着扩大了其分布的已知范围。我们发现了侵入性C. bilineata只有在天野川。我们的结果与 19 世纪和 20 世纪的记录一致，突出了历史数据在了解当前物种分布方面的重要性。我们的研究结果提供了大量的分布更新，可以更客观地评估物种保护状况。
