Khalimov Sh, Rakhmonov M, Li S, Azamov O, Peng Z, Sheraliev B (2026) New records of Triplophysa strauchii (Kessler, 1874) (Teleostei, Nemacheilidae) from the Zeravshan river drainage, Uzbekistan. Check List 22(2): 350-360. https://doi.org/10.15560/22.2.350 |  |
We report new records of Triplophysa strauchii (Kessler, 1874) from the middle Zeravshan river drainage in Uzbekistan. Previously, within this drainage, the species was known only from the upper reaches of this river in Tajikistan. Morphological and molecular (COI) analyses of specimens collected in 2022 and 2024 confirm that these specimens are conspecific with populations from the Syr Darya drainage. These findings document a significant westward range expansion of T. strauchii in the Zeravshan River. Specifically, the record from Narpay District represents the westernmost known limit of this species’ distribution, highlighting its continued westward expansion in Central Asia.
