- Abstract
Abstract: We describe a unique microsporidian species that infects the green stink bug, <italic>Chinavia hilaris;</italic> the brown marmorated stink bug, <italic>Halyomorpha halys;</italic> the brown stink bug, <italic>Euschistus servus;</italic> and the dusky stink bug, <italic>Euschistus tristigmus</italic>. All life stages are unikaryotic, but analysis of the consensus small subunit region of the ribosomal gene places this microsporidium in the genus <italic>Nosema</italic>, which historically has been characterized by diplokaryotic life stages. It is also characterized by having the reversed arrangement of the ribosomal gene (LSU –ITS‐ SSU) found in species within the “true <italic>Nosema</italic>” clade. This microsporidium is apparently Holarctic in distribution. It is present in <italic>H. halys</italic> both where it is native in Asia and where it is invasive in North America, as well as in samples of North American native <italic>C. hilaris</italic> collected prior to the introduction of <italic>H. halys</italic> from Asia. Prevalence in <italic>H. halys</italic> from mid‐Atlantic, North America in 2015–2016 ranged from 0.0% to 28.3%, while prevalence in <italic>C. hilaris</italic> collected in Illinois in 1970–1972 ranged from 14.3% to 58.8%. Oral infectivity and pathogenicity were confirmed in <italic>H. halys</italic> and <italic>C. hilaris</italic>. Morphological, ultrastructural, and ecological features of the microsporidium, together with a molecular phylogeny, establish a new species named <italic>Nosema maddoxi</italic> sp. nov.
