Th e three known North American species of Bryolymnia Hampson, 1908 are reviewed and three additional species are described as new. Two additional species, Elaphria ensina (Barnes, 1907) and Cryphia viridata (Harvey, 1876) are transferred to Bryolymnia as new combinations. Th e North American species are compared with related species in Central America. Adults of 11 species and male and female genitalia, where available, are illustrated. A peer-reviewed open-access journal Th e genus Bryolymnia
more » ... Hampson, 1908 includes 17 species occurring from western United States to Argentina (Poole 1989 ). An additional two species transferred to Bryolymnia, one from Elaphria Hübner, one from Cryphia Hübner, and the three species described below, bring the total to 22 species. Th e genus is associated with the Elaphrini on the basis of the weakly sclerotized area on the costa of the male valve near the apex of the digitus, and by the membranous transverse suture in the sacculus about 2/3 from its base that isolates the apical triangular sclerite that usually is more heavily sclerotized than the basal part of the sacculus. Bryolymnia can be recognized by the large, rounded or lobed plate-like process arising from the sclerotized rod that connects the dorsoanterior rod of the clasper to the costal margin of the valve. In most species this process extends dorsally beyond the dorsal margin of the valve. Superfi cially, in most species of Bryolymnia the medial fore wing area is pale and contrasts with black patches in the basal area, before or distal to the reniform spot, and/or in the costal part of the subterminal area. In some species the medial area is dark brown (and some species have forms in which the medial area may be dark or light); usually the dark patches are still contrasting, and frequently the reniform and orbicular spots are shaded with white scales. Th e genus is closely related to Hampsonodes Nye, which has 17 species ranging from Mexico to South America. Th ese species have an orange-red fore wing with thin white antemedial and postmedial lines that unite toward the hind margin to isolate the medial area in a rounded lobe. Th e genitalia are similar to those of Bryolymnia except that the vesica is very long and coiled. Th e relationship of Bryolymnia and Hampsonoides remains to be resolved and it appears that numerous species currently associated with Hampsonoides and Elaphria may belong in Bryolymnia. One species is transferred from Elaphria Hübner (B. ensina (Barnes, 1907) , comb. n.) and one (B. viridata (Harvey, 1876), comb. n.) is transferred from Cryphia Hübner.
