Abstract
"The genus Meris is revised for the first time. A study showed that the group was heterogeneous, as two very different types of genitalia, venation, and antennae were represented in the included species. When a second genus is recognized, the resulting split of the species will form two morphologically homogeneous groups; as no name was available, Nemeris, new genus, with type species Diastictis speciosa Hulst, is proposed. Relationships between the two genera are discussed; Meris has more apomorphic characters than does Nemeris. Keys are given to the species of both groups, based on male and female genitalia. All species are described, and both the adults and their genitalia are illustrated; distributional data are given for all species. The following species are described as new: Nemeris percne (Arizona), N. sternitzkyi (Arizona), Meris paradoxa (Arizona), M. patula (Montana), and M. cultrata (Arizona). Nemeris mexicola (Dyar) is a new combination, and Meris albocrenulata Cassino is placed as a synonym of Nemeris speciosa (Hulst), new combination. The members of Nemeris occur from Colorado and Utah to the Distrito Federal, Mexico, and those of Meris from southern British Columbia and southern Alberta to Arizona and New Mexico"--P. [1].
