The article presented the results of studies on the morphological and morphometric characteristics of the species Paracobitis longicauda (Kessler, 1872), collected in the summer of 2022 (06.06.2022) from the Sherabad River and its right tributary of Loyliksoy. The exact coordinates of the area, where the samples were taken, were obtained and a geographical map was drawn up. As ichthyological material, morphological, morphometric, and visual observations were made on samples (n=23) with TL=66.1-142.3, SL=54.4-121.2 mm. Information on the distribution and description of the natural range of Paracobitis longicauda in the Republic is presented. Numerical data on meristic and plastic parameters are presented in tabular form.
