The genus Lypoglossa Fenyes, 1918 is revised and redescribed. Descriptions and a key to species are provided. Four valid species are recognized: the Nearctic Lypoglossa angularis (M klin, 1853), L. franclemonti Hoebeke, 1992 and L. manitobae Gusarov, sp. n. (described from Manitoba), and the Palaearctic L. lateralis (Mannerheim, 1830). Euryusa obtusa LeConte, 1866 is transferred to Lypoglossa and considered a valid subspecies of L. angularis. Three subspecies are recognized within Lypoglossa angularis: L. a. angularis (M klin, 1853), distributed in coastal Alaska, British Columbia, and western Washington and Oregon; L. a. fenyesi (Bernhauer, 1907), from interior Alaska, Yukon Territory, interior British Columbia, and south through the high mountains of the western United States, to Arizona and New Mexico; and L. a. obtusa (LeConte, 1866), known from Quebec, Newfoundland, Maine and New Hampshire.
