Abstract Scale insects of the genus Protortonia Townsend (Hemiptera: Coccoidea: Monophlebidae: Llaveiini) are restricted to Mexico, the Caribbean and Central and South America, and are rarely collected. We provide keys to the tribe Llaveiini and to species of Protortonia based on adult females and available nymphal instars. We transfer Marchalina azteca Ferris to Protortonia as P. azteca (Ferris) comb. nov. We revise the genus based on all available instars, redescribe six species – P. azteca from Mexico, P. cacti (L.) from Puerto Rico, P. crotonis Reyne from the Netherlands Antilles, P. ecuadorensis Foldi from Ecuador and Colombia, P. navesi from Brazil and P. primitiva (Townsend) from Mexico, and describe one new species, P. quernea sp. nov. from Costa Rica. We designate a lectotype for M. azteca and Ortonia primitiva Townsend. We also synonymise Ecuadortonia Ben‐Dov with Laurencella Foldi and transfer Ortonia uhleri Signoret to Laurencella as L. uhleri (Signoret) comb. nov. Keywords: Protortonia MonophlebidaeCoccoideataxonomycassava Acknowledgements We are very grateful to the following people for arranging museum loans: Douglass Miller and Greg Evans of the USDA, Beltsville, Maryland, USA, for specimens of Protortonia and other llaveiines; Herbert Zettel of the International Research Institute of Entomology, Naturhistorisches Museum in Wien, Austria, for the type material of Ortonia uhleri; Carlos Lamas of Museu de Zoologia, Universidade de São Paulo, Brazil, for some Hempel material; and Willem Hogenes of Universiteit van Amsterdam, Zoölogisch Museum Amsterdam, Amsterdam, Netherlands, for type material of P. crotonis. Imre Foldi of the Muséum National d'Histoire Naturelle, Paris, assisted with the loan of types of P. ecuadorensis and helped DJW to examine type specimens of Laurencella and Neohodgsonius during a visit to Paris in 2007. Alex Segarra of the University of Puerto Rico, Lajas Agricultural Experiment Station, kindly searched for P. cacti on Opuntia on Puerto Rico. Charles Martins de Oliveira of Embrapa Cerrrados, Brazil, generously provided specimens of P. navesi and information on its biology. Francisco Posada of USDA, Beltsville, Maryland, kindly sent some specimens of L. colombiana for our reference purposes. Special thanks to Takumasa Kondo of the University of California, Davis, who provided specimens and information on Colombian llaveiines, read a draft of our manuscript, and scanned the drawings. Chris Hodgson and Gillian Watson kindly reviewed the manuscript and provided helpful comments. This work was supported in part by the US National Science Foundation (Partnership for Enhancing Expertise in Taxonomy program, under Grant No. 0118718) and by Hatch funding from the California Agricultural Experiment Station, both to PJG.
