Phalangium opilio is 'the most widespread species of harvestman in the world', occurring natively in Europe, and much of Asia, and having been introduced to North America, North Africa and New Zealand.
Aug 4, 2021 · We assembled the first harvestman draft genome for the species Phalangium opilio, which bears elongate, prehensile appendages, made possible by numerous distal articles called tarsomeres. Here, we show that the genome of P. opilio exhibits a single Hox cluster and no evidence of WGD.
