Studies of the Mexican Deltocephalinae -1, 2 Aligia and Some New Allied Genera and Species (Homoptera: Cicadellidae)
No full textAuthor Institution: Entomology Research Division, Agr. Res. Serv., U. S. Department of Agriculture, Washington, D. C., Professor Emeritus, Department of Zoology and Entomology, The Ohio State University, Columbus, OhioThe Mexican species of Aligia Ball and related genera are largely unknown or undescribed. Hepner (1942) published a study of the 32 species of Aligia known to occur in the United States, and some of these will undoubtedly be found in Mexico eventually. In this paper we describe three new species of Aligia; one new species of Frequenamia DeLong; and two new genera, one with two new species and the other with a single new species. All holotypes and allotypes are in the DeLong Collection; paratypes will be deposited in the collection of the United States National Museum
