Interpretive Summary: Flat mites are important agricultural pests on crops, forestry, ornamentals and fruit trees. Their damage and control cost many millions of dollars annually world wide. This article reports the finding of a Mediterranean flat mite species in the Americas associated with timber trees. The distribution and description of the damage were included to help with the understanding of this emerging invasive species on Pines. This study will be important to plant protection officers, extension workers, agriculture and forestry scientists, quarantine officers, entomologists and ornamental plant growers.

Technical Abstract: Cenopalpus wainsteini (Livschitz and Mitrofanov, 1967), a mite species in the family Tenuipalpidae, was discovered on Pinus sylvestris Thumb. in Lima, Peru and represents the first record of this species in the Americas. Previously, only Cenopalpus pulcher (Canestrini and Fanzago, 1876) and Cenopalpus officinalis (Papaioannou-Souliotis, 1986) have been reported from the Nearctic and Neotropic regions. The current paper describes and illustrates the morphological characters of female, deutonymph, protonymph and includes the first description of the larval stage of the species. Species of Cenopalpus wainsteini collected in Peru were compared with specimens collected in Italy, as well as with the original description by Livschitz and Mitrofanov of specimens from Ukraine and the re-description of the species by Arabuli and Kvavadze (2013) based on specimens collected in Georgia. Furthermore, notes on Cenopalpus lineola (Canestrini and Fanzago, 1876) are included since is frequently associated with Cenopalpus wainsteini. Severe damage symptoms caused by this flat mite on its host plants were observed and are discussed herein.
