Resumo-The distributions of 117 Canary Island orthopteroid species belonging to Orders Blattaria, Mantodea, Orthoptera, and Phasmida are presented based on the authors' collections, museum specimens, and literature since the last list in 1954. The number of species in each order and the percentage endemic to the archipelago are: Blattaria 24 (50%); Mantodea 9 (67%); Orthoptera 83 (37%), and Phasmida 1 (0%). The same for families of Orthoptera follows: Acrididae 41 (41%); Gryllidae 18 (17%); Gryllotalpidae 2 (0%); Pamphagidae 4 (100%); Pyrgomorphidae 1 (0%); Tetrigidae 1 (0%); and Tettigoniidae 16 (44%). Orthopteroid species diversity and the number of endemics were greatest on Tenerife (82 species, 24 endemics), followed by Gran Canaria (64 species, 17 endemics), and La Gomera (49 species, 14 endemics); Fuerteventura had the fewest number of species (28) and the lowest number of endemics (5). Tenerife supported the highest number of single-island endemics (8) and La Palma had the lowest (1). The highest percentages of endemics, 27% to 29%, occurred on Tenerife, La Gomera, La Palma, Lanzarote, and Gran Canaria; Fuerteventura had 18% and El Hierro 17%. New species, changes in nomenclature, and unconfirmed records are discussed, as are taxonomic problems ecountered in taxa of the acridid genera Sphingonotus and Acrotylus.
