825FBD07315A5C79BE9CA8F43E501D9E.taxon	etymology	Etymology. The adjective uralensis comes from the name of the Ural River, which literally means lives in the basin of this river.	en	Turbanov, Ilya S., Bolotovskiy, Aleksey A., Artaev, Oleg N., Gandlin, Aleksandr A., Levina, Marina A., Vasil’eva, Ekaterina D., Levin, Boris A.

825FBD07315A5C79BE9CA8F43E501D9E.taxon	description	Qualitative characters. The breast in front of the posterior edge of the base of the pectoral fins usually lacks scales; some individuals have 1 – 3 scales along the midline towards the throat [character state 1 following Naseka et al. (2006)] (Fig. 8 A).	en	Turbanov, Ilya S., Bolotovskiy, Aleksey A., Artaev, Oleg N., Gandlin, Aleksandr A., Levina, Marina A., Vasil’eva, Ekaterina D., Levin, Boris A.

825FBD07315A5C79BE9CA8F43E501D9E.taxon	distribution	Distribution. The type specimens were collected from the Bolshoy Kizil River, a tributary of the Ural River, near Ryskuzhino (53.3161 ° N, 58.3351 ° E), Republic of Bashkortostan, Russia (see Fig. 6). All other gudgeons genetically confirmed as the same species were caught in different locations in the Ural River basin (see materials). Although we suppose that the whole Ural River basin is inhabited by the Ural gudgeon, one may not exclude that some parts of the extended Ural drainage are inhabited by other species. According to Shaposhnikova (1964), the gudgeon is widespread throughout the Ural River. The gudgeon is especially abundant in the mountain tributaries of the Ural and in its upper reaches, where it is numerous in riffles and sandbanks; this is partly confirmed by the data of Martynova and Vasil’eva (2021) as well as by our observations.	en	Turbanov, Ilya S., Bolotovskiy, Aleksey A., Artaev, Oleg N., Gandlin, Aleksandr A., Levina, Marina A., Vasil’eva, Ekaterina D., Levin, Boris A.
