The Cercopidae family constitute the largest group of xylem sap-sucking insects. Several species are important pests of sugar cane and grasses. In America there are 460 species and 65 subspecies in 60 genera. In Mexico, the total number of species is unknown and there is no inventory of specimens in the collections or taxonomic keys. In the present research, we study entomological collections to trace the distribution of genera and species and constructed taxonomic keys for their identification, based on external morphology and male genitalia. The Cercopidae of the country included 3 recognized tribes, Neaenini Fennah, 1968, Ischnorhinini Schmidt, 1920 and Tomaspidini Schmidt, 1922, in addition to the recently proposed Microsarganini Hamilton, 2016. We reported 39 described species, 1 subspecies and 1 undescribed, belonging to 10 genera. The most diverse genera were Ocoaxo Fennah with 16 species and Prosapia Fennah with 8. Aeneolamia Fennah includes 3 species and 1 subspecies, Iphirhina Fennah and Neaenus Fowler 3 species each, Microsargane Fowler and Olcotomaspis Lallemand 2 species each, and Mahanarva Distant, Huaina Fennah and Zulia Fennah 1 species each. This is the first complete compilation of the Cercopidae recorded for Mexico.
The genus Aeneolamia includes eight described species and 32 subspecies widely distributed in America. In Mexico, two species (A. contigua and A. albofasciata) and one subspecies (A. contigua campecheana) are recognized. In a recent study of Cercopidae in Mexico, a new species of Aeneolamia was noted from Oaxaca, Mexico based on body color and the ornamentation patterns of tegmen, without a formal taxonomic description. To test the hypothesis of an extant new taxon within the genus a comprehensive analysis of intraspecific morphological variation from 46 morphological features was performed, four related to tegmen color patterns in both sexes, six to male genitalia, and 36 continuous characters measured in specimens of both sexes of Mexican Aeneolamia from several geographical localities using traditional univariate, multivariate morphometric, and geometric morphometric methods. This is the first time that this approach has been used in Cercopidae. Aeneolamia danpecki Castro, Armendáriz & Utrera, sp. nov. from Oaxaca showed pronounced morphological differences in tegmen coloration patterns, the shape of different elements of the male genitalia, and body measurements compared to the other Mexican members of Aeneolamia; therefore, it is described as a new species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
