When collecting aquatic organisms in overgrown water bodies and rivers, a hydrobiological scraper was used. Data on the first finds of 5 species from 5 families in the territory of Udmurtiya and 6 species from 4 families in Bashkiriya are given. They are respectively as following: Orectochilus villosus (Gyrinidae), Haliplus confinis (Haliplidae), Rhantus bistriatus (Dytiscidae), Helophorus redtenbacheri (Helophoridae), Limnebius crinifer (Hydraenidae) in Udmurtiya, and Haliplus varius (Haliplidae), Ilybius fenestratus, Hydroporus palustris, Graptodytes bilineatus (Dytiscidae), Helophorus brevipalpis (Helophoridae), Limnebius cf. parvulus (Hydraenidae) in Bashkiriya.
