Summary taken on the Entomological Society of America web site: “This comprehensive study of nearly 10,000 plant-hoppers corrects the ambiguities in the key and descriptions of Pissonotus by Morgan and Beamer (1949), applies their definitions to world fauna, addresses the suspicion that there were undescribed species in the genus, and presents a phylogenetic analysis of the genus. The end result is identification aid of the genus.”
