As a result, a total of 30 species belonging to 24 genera and eight families were recognized: 12 Dytiscidae species, eight Hydrophilidae species, three Haliplidae species, two Scirtidae species, two Gyrinidae species, one Noteridae species, one Elmidae species, and one Psephenidae species. Composition and habitus photographs of all collected aquatic beetles, habitats, and the diagnostic characters of C. parallelus and S. sobrinus are provided.
