Abstract

Specimens of webspinners found on Fuerteventura Island (one of the Canary Islands) were provisionally identified as Embia cf. savignyi Westwood, 1837 (Embioptera: Embiidae). Embia savignyi is native to northeastern Africa and the population reported from the Canary Islands is introduced. The report provides location data, photographs of specimens, a description of cytogenetic characteristics, a DNA barcode, and a description of the morphological intrapopulation variability. A morphologically based identification key for Canary Island webspinners, composed of three alien species, is also provided.
