Annotated type catalogue of the leafhoppers and treehoppers (Insecta: Hemiptera: Auchenorrhyncha) deposited in the collection of Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias, Guanajuato, Mexico

The Insect Collection of the Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (CNI-INIFAP) in Guanajuato state is one of the oldest collections in Mexico with remarkable and historical holding of 240,000 specimens primarily composed of insect orders of economic importance. With 14,500 specimens obtained over 70 years from most agricultural areas in Mexico, Auchenorrhyncha is well represented in the collection, but has received little attention and its value has been largely ignored in research. However, it holds a valuable stock of types designated by taxonomic authorities such as James P. Kramer, David Young Jr., Robert F. Ruppel, Dwight M. DeLong, and Charles. C. Plummer. Here, an annotated Auchenorrhyncha catalogue of the Insect Collection of the INIFAP is presented. Complete information for each species, including those designated as types, specialized references, labels data from original description, and high-quality photographs are given. A total of 28 types (one holotype and 27 paratypes) are listed, of which six species belong to Membracidae and 22 to Cicadellidae. A total of 147 Auchenorrhyncha species are retained into the INIFAP collection, 132 spp. of 68 genera for leafhoppers and 12 spp. of six genera for treehoppers. Three leafhopper species: Parallaxis ornata Osborn, 1928, Rhabdotalebra signata (McAtee, 1926), and Diceratalebra sanguinolinea (Baker, 1903), are presented as new records for Mexico.
