Eriophyoid Mite of the Genus Trisetacus Reported on Juniperus excelsa in Lebanon


We report for the first time the occurrence of Trisetacus acari Eriophyoid parasite infesting Juniperus excelsa seeds in Lebanon. The specimen studied belong most probably to the species T. kirghizorum (Shevchenko 1962) living on J. semiglobosa in the Kirghiz mountains. We suggest that Trisetacus spp. found in the seed cones of Kirghiz junipers as well as J. excelsa comprise a complex of cryptic species that might be distinguished using molecular markers. It is necessary to revise the group cupressi in the genus Trisetacus and an integrated phylogenetic study of the mites belonging to this genus could elucidate the patterns of eriophyoid mites evolution on conifers and could help in a better resolution of the Juniper phylogeny.
