Visoka is a of small winter stoneflies in the Nemouridae, established by Ricker in 1952. These insects are part of the order Plecoptera, a group of aquatic insects whose nymphs inhabit cold, well-oxygenated freshwater environments. The genus has been recorded from western North America including Alberta, Alaska, British Columbia, California, and Idaho. As with other nemourids, are typically small with reduced wing venation.
