RESUMO
From citizen science data we report the first records of blue to violet-colored oniscideans (Oniscidea: Isopoda), indicating potential invertebrate iridescent virus (IIV; Betairidovirinae: Iridoviridae) infection: in Africa, South America, and Oceania; and of the new hosts Armadillidium nasatum and Balloniscus sellowii. DNA sequencing of indigo Porcellio scaber confirms the presence of Invertebrate iridescent virus 31 in Australia. Beyond the Oniscidea, new, putative IIV hosts are identified: hoverfly pupae (Eristalinae), a tortrix moth larva (Phaecasiophora niveiguttana), and a millipede (Harpaphe haydeniana). In addition, the purported positive correlation between virion diameter and wavelength of iridescence is analyzed qualitatively for the first time.
